Lip cancer is one of the most common types of oral cancers. It originates mainly in the lips and can be very dangerous if not treated in time. Though the cases of this type of cancer are rare worldwide, it is still a form of cancer and may spread to other organs also. The damage may be irreparable and timely treatment is the only option to get rid of these malignant cells. Tongue cancer is a form of cancer characterized by uncontrolled division and maturation of the cells lining the tongue as well as the oropharynx (a small part of the throat located at the rear of the mouth). Tongue cancer is usually included under the umbrella of "mouth cancer" and thus is sometimes also known as oral cancer. As per the National Cancer Institute, approximately 10,000 cases of tongue cancer are diagnosed annually in the US, out of which nearly 2000 die from the condition. Excessive use of tobacco is often considered to be the prime risk factor for tongue cancer, accounting for close to 75 percent of all cases worldwide. 2. Specific goals. 1.

Content of the topic Lip cancer Lip cancer occurs in lips and affects many important activities of the victim. Lips are the main opening of the mouth and play an important role in the food intake. They also enable a person to speak and pronounce the words correctly and make different sounds through his mouth. They are soft, flexible and the lower lip is generally larger than the upper lip. Development of cancerous cells in the lips can be damaging as it will impact the ability to intake food and will also affect a person's speaking abilities. Lips also play an important role in presenting important gestures like frown, smile, etc. It is also one of the most sensitive organs of the body and plays a crucial role in sexual activities. Hence, presence of cancerous cells in the lips may put restriction on many basic but important activities of a person. Lip cancer develops mostly in the lower lip and spreads to other areas gradually. The cancerous cells initially attack the cell layer present on the surface of the lips and penetrate further as the intensity of the disease increase. In most of the cases, the cancerous or malignant cells develop in the squamous cells (squamous cells are the cells forming the layer of the lips). Hence, squamous cell carcinoma is the most common form of this cancer. The malignant cells spread rapidly and form cancerous tumors. Basal cell cancer is another type of cancer of the lips. The infected cells are less harmful as compared to those in the squamous cell carcinoma and do not spread to other areas. Tumors formed by the infected cells can be benign or cancerous. Benign tumors usually do not invade the healthy tissues. They are less destructive and do not spread to other parts of the body. Benign tumors are completely curable and the chance of their recurrence is very less. On the contrary, cancerous tumors are highly destructive and cause the maximum damage possible. Their primary targets are the live and healthy tissues present on the surface of the lips and obstruct their functioning. They also attack live cells present in the adjacent areas and replace them by the infected malignant cells. A tumor is formed when an excess number of malignant cells accumulate in a particular area. The tumor can also spread to other parts of the body through the lymph nodes or the bloodstream. It is quite difficult to eliminate the malignant cells as they may recur after a certain period. The main lip cancer causes are: 1. Tobacco: This is largely considered as the primary reason for the development of oral cancer and also of lip cancer. Smoking of cigarettes, pipes, cigars and consumption of tobacco on a regular basis is a major cause of this ailment. Chain smokers and the people who consume tobacco at a regular interval in the whole day are considered at the highest risk of lip cancer. 2. Alcohol: Alcohol too is considered as one of the most common cause of lip cancer. Consumption of excessive alcohol or drinking alcohol on a daily basis is a habit that can cause other problems as well as lip or oral cancer. If the individual is consuming alcohol with tobacco, the risk of lip cancer is very high. 3. Sun: Excessive exposure to sun is also a major cause of lip cancer. This risk can be reduced by using a proper lip balm or a lotion to protect the lips from ultra-violets rays of the sun. One should always protect the face and tender parts of the face such as the lips, with the help of a hat or an umbrella from the sun. 4. Genetics or Hereditary: Most of the times, when a person has had neck or head cancer, one can develop oral cancer or lip cancer easily. This can be termed as metastasis of the cancer. This cancer can spread to other parts of the face as well. 5. Chewing betel nut: This is a very famous practice in various parts of India and other nations of South Asia. This causes a lot of cancer developments in many of the organs of the face, especially the mouth and the lips. Mucosa carcinoma is the cancer which develops in the cheeks and can spread to the lips as well. 6. Human papillomavirus (HPV): This is the infection which is associated with the cervix, vagina, vulva and the penis. Even after this cancer being associated with the reproductive organs of the body, it has a strong connection in causing lip and mouth cancer. 7. Age: As an individual advances in age, the risk of developing this cancer will rise. It is believed that this cancer arises in an individual after the age of 45 years. 8. Gender: This cancer is more common in men than in women. This cancer is more common in men because the consumption of liquor and tobacco is higher in that gender. 9. Poor oral cleanliness: Poor oral hygiene is also considered as a very common cause of this cancer. This is also a cause of spread of this cancer to other parts of the face, like the jaw and mouth. Generally this cancer is developed in the inner surface of the lip. 10. Deficiencies in the diet: Deficiencies in the food such as low intake of iron, folic acid, vitamins such as A, C and E are also a lip cancer cause or they may increase the level of this cancer. 11. Weak immune system: The individual who have other illnesses such as HIV or other major issues, are prone to this cancer on a larger extent, because the immunity level is very low because of the intake of heavy medicines. These are a few very common lip cancer causes which can be avoided by an individual very easily, except age. This cancer mostly rises when continuous smoking and alcohol consumption is observed in an individual. If the intake of these things is reduced, the risk of developing this cancer is also reduced. The ways by the lip cancer diagnosis can take place are as follows: Physical Examination: Generally, the first step to detect this type of cancer is a normal physical screening of the lips. The doctor or a dentist will inspect the lip cancer stage by inserting gloved fingers into the mouth, and feel if there is any abnormal growth inside the mouth or on the lips. This will also determine if there is any oral cavity in the mouth. A mirror and light is used to check the inner portion of the mouth and the sides of the lips. This physical exam not only checks the lips, but also the other organs of the body such as cheeks, gums, floor of the mouth etc, to see if the cancer has spread anywhere else than lips. Endoscopy: Endoscopy is a process which is used for detection of various organs including the organ where cancer has spread. An opening is made in the body and an endoscope is inserted into the body via that particular opening, to have a look at the organs. This instrument is in a shape of tube. It has a lens attached to it so that a clear picture can be seen. The lens is very clear to even detect the cancerous developments in the tissue or o o o o o o o o o o the nodes. The tissue which is removed with the help of an endoscope is checked under the microscope to detect any signs of cancer. X-Rays: This is a very common test as well. An x-ray is a beam which can go through the body to detect if there is any growth in the organ. An x-ray of the mouth will be done to check if there is any tumor in the lips of an individual. Biopsy: This is a process which is done by a pathologist. In this, cells which are removed from the infected area are checked minutely under a microscope. If there is any indication of Leukoplakia, then cells from other parts of the body are taken and checked for the metastasis of the cancer. MRI: MRI stands for Magnetic Resonance Imaging. This is a test which uses magnets, radio active waves and a computer to check the organs of the body. This is a test which will give out a detailed summary with the help of pictures of the organ which needs to be detected. This test is also called as nuclear magnetic resonance imaging (NMRI) CT scan: This is a test which involves capturing the images of various organs in different angles. This is a scan which helps in detecting even the smallest problem in the body. While conducting this test, a dye is either injected into the veins of the body or is swallowed by the patient; this helps the doctor to have a better look at the tissue which has an abnormality. This process is known as computed tomography. Barium Swallow: This is a test which has a series of X-ray conducted of the targeted area. This is a test in which the patient consumes barium, which is a metallic silver liquid which helps in exfoliating the area which is carrying the ailment. The other name for this process is also known as upper GI series. Exfoliating Cytology: This is a test which is targeted to take the cells from the lip. This is done with the help of cotton, or a wooden stick. These things are used to scrape out the cells gently from the layers of the lips. The next step is it to view these cells under the microscope to check for any signs of malignancy. Lip cancer Stages Stage 0 This is considered as the initial stage of the cancer The other name of this cancer is called as Carcinoma Situ Abnormal cells are found on the lining of the lips This is a stage where these abnormal cells may become cancerous at a later stage if the treatment does not start soon If the cells are not treated then, they may spread in the nearby tissues as well Stage 1: This is the stage where in the cells have developed as cancer The size of the cancer is close to 2cm or many a times smaller than that The cancer is not very big and can still be treated with proper medications This cancer has not reached the lymph nodes Stage 2: In this stage, the size of the cancer is more than 2 cm but smaller than 4 cm This is the stage where in the cancer is growing and the treatment should start as soon as the detection takes place o This is the cancerous stage where in the cancer has reached a higher state but not the lymph nodes o One must treat this cancer soon, or else the treatment method of lip cancer operation will be the only option that one will remain with Stage 3 o In this lip cancer stage, the tumor has become big and in most of the cases is visible o This is the stage where in the size of the cancer has reached a minimum of 3 cm o The cancer has also spread on to the lymph nodes o The side where the cancer has spread, on the same side and the neck tissue is also beginning to get damaged o If this is the case, then the size of the cancer is almost 4 cm Stage 4 o Stage 4 of the cancer is divided into 3 categories: a. Stage 4A b. Stage 4B and c. Stage 4 C Stage 4A: This is the stage which states that cancer has covered maximum of the tissue of the lip In this stage, the cancer in most of the cases has reached the nearby tissues or the nearby bone. This would include the jaw, tongue, floor of the mouth etc Most of the times, the skin of the cheeks and chin are also affected by this cancer If the cancer has spread to the lymph nodes, of any side the length if the cancer is almost 3cm. This is a cancerous growth which is observed very close to the neck Many a times, it also spreads in the tissue of the bone which is very to the lips. This can be the jaw or the tongue (primarily) When this cancer spreads to other parts of the mouth or in some cases body, it is of minimum 3 cm but not more than 6 cm in length Stage 4B: In this stage, the cancer may spread to one or more lymph nodes The cancer will spread to the nodes which are larger than 6 cm The cancer has also spread to the other muscles or the bones extensively This cancer may have also spread in the lower part of the skull and or the carotid artery Stage 4C: In this stage, the cancer has gone and spread beyond the lip and other parts of the mouth The first organ that this cancer would affect is the lungs o The size of the tumor is not defined in this stage and can spread anywhere in the body Treatment options for lip cancer can include one or more of the following: Surgery Surgery to remove the tumor is a common treatment for lip cancer. Depending on the size of the cancer on the lip, part of the tongue, jaw and palate also may be removed. This can affect the way many talk, swallow or chew, so reconstructive surgery is usually takes place to help rebuild these sections of the mouth that were removed. Radiation Therapy An option for very small tumors on the lip or people who cannot tolerate surgery, radiation therapy can be given internally or externally. It also is used prior to surgery to reduce the size of the tumor as well as after surgery to destroy any remaining cancer cells in the area. Chemotherapy Typically given at the same time as radiation therapy to treat lip cancer, the use of chemotherapy can result in infection and pain in the mouth and gum area. Commonly used chemotherapeutic drugs include 5-fluorouracil, bleomycin, carboplatin, cisplatin, docetaxel, ifosfamide, methotrexate and paclitaxel. Targeted Therapy A targeted anticancer therapy called Erbitux also can be used to treat lip cancer. It is usually is given in combination with radiation or chemotherapy. Designed to bind to a substance called epidermal growth factor receptor (EGFR) that is found on the surface of lip cancer cells, targeted therapies can cause less harsh side effects as compared to chemotherapy. Tongue Cancer Important Indicants of Tongue Cancer Among all the symptoms, the first one that is noticed is a red or white spot on the tongue. This spot may vary in size from being small to medium, and can also be found on the lining of the mouth or gums. The spot turns into a firm spot and develops raised edges. This indicates that the cancer is progressing. Experiencing throat pain or having difficulty while chewing or swallowing food is also a common symptom of the condition. It is known as dysphagia. Note that, the same is also a common symptom of strep throat (sore throat). However, if it is accompanied by the symptoms mentioned above or below, then it is most likely an indication of a tongue cancer. Bleeding is a usual symptom seen in people with cancer of the tongue. The cancer spots are too tender to tolerate pressure of any kind, and break open due to friction caused by chewing, swallowing or drinking, etc. thus, they bleed. Apart from bleeding, patients may also develop ulcers that show no signs of healing. The voice of the person may also seem a little different from the usual tone, accompanied by an ache localized in the middle or inner ear. The breath and taste of the mouth goes from bad to worse. This is because tongue cancer is like an infection. It produces a foul breath in the mouth, and the tongue has a disgusting taste. This foul smell due to the cancer is different from typical bad breath. Other tongue cancer symptoms include: Loose teeth or tooth for no obvious reasons Neck pain, jaw ache Reduced movement of the tongue A lump that develops at the back of the throat or in the lining of the mouth Abnormal weight loss A feeling of something stuck in the throat Abnormal changes in the taste As mentioned, if the cancer is detected when it is still localized, then using a combination of surgery, radiotherapy and chemotherapy the condition could be completely cured. The treatment procedures highly depend on the location of the cancer, and the extent of its spread. If it is localized and small, then it could be removed through minor surgery. Extensive surgical procedure could be required for larger tumors. For a cancer that has spread to the neck, the treatment comprises getting rid of the cancerous lymph nodes and other tissues. Most people may require to undergo a reconstructive surgery after the surgery to remove the cancer. This is to help them regain their ability to talk and eat. To conclude, the best way to deal with cancer is not letting it develop in the first place. Although, there is no assured way to prevent tongue cancer, there are some measures that may reduce the risk of developing the condition. These include avoiding using tobacco, drinking alcohol in moderation, and having a diet rich in fruits and vegetables. Equally important is to make regular visits to your dentist so that you can rule out any precancerous changes. TNM Stages of Tongue Cancer The terms TNM stand for Tumor, Node and Metastasis of the cancer. They help explain the size of primary tumor (T), if the cancer has spread to the lymph nodes (N) and if the cancer has spread to other parts of the body (M). Let us have a look at each stage separately. Tumor Stage The tumor stage is divided into 4 stages. The T1 stage means the tumor is still present in the tongue tissues and is about 2 cm in size. The T2 stage means the tumor is larger than 2 cm in size, but it is smaller than 4 cm. When the tumor is said to be in the T3 stage, it means it is larger than 4 cm in size. The T4a tumor means it has spread from the tongue to the nearby tissues of the sinuses and skin. When the tumor spreads to the spaces behind the jaws, upper jaw muscles, base of the skull, etc. Node Stage The node stage is also broken down into 4 stages. The N0 stage means there are no cancer cells present in the lymph nodes. The N1 stage means there are cancer cells present in one lymph node on the same side of the cancer. However, the lymph node is no more than 3 cm away from the cancer. N2a stage is when 1 lymph node on the same side of the cancer is affected, but is more than 3 cm away, but less than 6 cm across. The N2b stage means there is more than just one lymph node affected by the cancer, but these lymph nodes are not more than 6cm away. Also, these lymph nodes are present on the same side of the neck. In case of N2c stage, cancer has spread to lymph nodes on both sides of the cancer, but are not more than 6 cm away. The N3 stage means there is at least one lymph node affected by the cancer and present more than 6 cm away from the site of cancer. Metastasize Stage The 'M' stage is divided into just two parts. The M0 stage means the cancer has not spread to any other part of the body. M1 stage means the cancer has spread to other distant parts of the body, like the lungs. Surgery treatment Surgical removal of the tumor is usually the first option in the treatment. The size, location and depth of the tumor influences the surgery. An early initiative for the treatment helps in removing small cancers through the mouth, using laser cautery. This ensures the removal of the entire tumor without affecting the normal function of the tongue. In cases, where in, the depth of the tumor has increased, removal of the nearby neck lymph nodes may be included in the surgery. For tumors that are larger than normal, surgeons utilize the latest of the techniques, without ill aftermath of the surgery. Radiation Therapy After conducting surgery, radiation treatment may follow. There may remain some possibilities of untreated cancer cells in the tongue, even after the surgery. To remove these cells, radiation therapy involves exposure of high-energy X-rays to kill the remainder cancer cells. The therapy also uses radioisotopes or electronic beams for the same purpose. The therapy is a localized treatment; it deals with cancer cells only in the treated area. The patient may receive two kinds of this therapy; internal and external radiation. Common side effects of radiation therapy comes up in the forms of skin reactions, tiredness, loss of appetite, etc. However, these and other side effects can be easily controlled and treated. Chemotherapy Chemotherapy may be required in extreme cases, where in, the tongue cancer may have extended itself to the nearby lymph nodes in the neck or other areas. In short, this type of treatment is required when the cancer is no more localized and has spread elsewhere. Medical oncologists may administer chemotherapy orally in the form of medication or it can be given through a vein. This treatment basically involves the use of drugs to destroy cancer cells. Reconstructive Surgery This surgery is often required to retain functions of the tongue (speech, swallowing, eating) after its surgical excision. It is a procedure to restore the normal surface architecture of the tongue, which might have been changed after surgical removal of the tongue tissue. This surgery is basically performed to improve the facial appearance of the patient. Rehabilitation Professionals who specialize in dietetics, speech therapy, swallowing therapy, physical therapy and occupational therapy are the responsible persons in rehabilitation. This step marks the last phase in the treatment of tongue cancer. The number of sessions required by the patient depends upon the extent of the cancer and also the degree of the after-effects of the surgery on the tongue. People going for such sessions, are taught how to swallow, eat, speak and retain all the normal functions of their tongue. People undergoing the various treatment methods for tongue cancer must be mentally prepared for everything that follows once the treatment is initiated. However, as we can see, the procedures that are undertaken by the professionals, ensure complete safety and positive results post-treatment depending upon the stage of the disease. 5.

The salivary glands are located around the mouth. They produce saliva, which moistens food to help with chewing and swallowing. Saliva contains enzymes that begin the digestion process, and help cleanse the mouth by washing away bacteria and food particles. By keeping the mouth moist, saliva helps to keep dentures, retainers, or other orthodontic appliances in place. 2. Specific goals. 1.

Content of the topic Salivary gland tumors are abnormal cells growing in the ducts that drain the salivary glands. Causes There are three pairs of major salivary glands. The largest are the parotid glands, located in each cheek over the jaw in front of the ears. Two submandibular glands are at the back of the mouth on both sides of the jaw. Two sublingual glands are under the floor of the mouth. There are also thousands of minor salivary glands around the rest of the mouth. All of the salivary glands empty saliva into the mouth through ducts that open at various locations in the mouth. Salivary gland tumors are rare, especially in children. Swelling of the salivary glands is most commonly due to: Abdominal surgery Cirrhosis of the liver Infections Other cancers Salivary duct stones Salivary gland infections Sarcoidosis Sjogren syndrome The most common type of salivary gland tumor is a slow-growing noncancerous (benign) tumor of the parotid gland that gradually increases the size of the gland. However, some of these tumors can be cancerous (malignant). Malignant salivary gland tumors are usually carcinomas. Symptoms A firm, usually painless swelling in one of the salivary glands (in front of the ears, under the chin, or on the floor of the mouth); the size of the swelling gradually increases. Difficulty moving one side of the face, known as facial nerve palsy Exams and Tests An examination by a health care provider or dentist shows a larger than normal salivary gland, usually one of the parotid glands. Tests may include: X-rays of the salivary gland (called a ptyalogram or sialogram) to look for a tumor CT scan or MRI to confirm that there is a growth, and to see if the cancer has spread to lymph nodes in the neck Salivary gland biopsy or fine needle aspiration to determine whether the tumor is benign or malignant Treatment The recommended treatment is usually surgery to remove the affected salivary gland. If the tumor is benign, no other treatment is usually needed. Radiation therapy or extensive surgery may be needed if the tumor is cancerous. Chemotherapy is sometimes used in patients who are considered high risk, or when the disease has spread beyond the salivary glands. Outlook (Prognosis) Most salivary gland tumors are noncancerous and slow growing. Removing the tumor with surgery usually cures the condition. In rare cases, the tumor is cancerous and further treatment is needed. Possible Complications Cancerous tumors may cause further complications, including spread to other organs (metastasis). Rarely, surgery to remove the tumor can injure the nerve that controls movement of the face.
