Breast Cancer
Presentation by Dr Mafunga
Breast cancer in the UK
• Breast cancer is the second most common cancer in women.
• Around 1 in 9 women will develop breast cancer
•
It most commonly affects women over the age of 50 years, rare
before the age of 35
• 45,972 people were diagnosed with breast cancer in 2007, of whom
over 99% were women
• 15,000 deaths per year
• one percent of all breast cancer occurs in men
What does a normal breast look like
•lobules – glandular tissue ( make
milk after pregnancy)
•ducts - take milk from the lobules
to the nipple.
•fatty tissue and supporting
connective tissue.
•blood vessels, lymph channels and
nerves
• Many women find that their breasts become more lumpy and tender
before periods.
• Breasts also alter their size and shape with increasing age,
pregnancy, and with marked weight changes.
•
What is important is that you get to know your own breasts - how
they look and feel - and report any changes promptly to a doctor
What is cancer?
Cancer is a disease of the cells in the body. Cancer cells are
abnormal and multiply out of control.
A malignant tumour is a lump of cancer cells which continue to
multiply. Malignant tumours invade into nearby tissues and organs,
which can cause damage.
Malignant tumours may also spread to other parts of the body via
the bloodstream or lymph nodes and form secondary tumours
(metastases)
Invasive or in situ?
• Most breast cancers are diagnosed when a tumour has grown from
within a duct or lobule into the surrounding breast tissue. These are
called invasive breast cancers.
• Some people are diagnosed when the cancerous cells are still
totally within a duct or lobule. These are called carcinoma in situ, as
no cancer cells have grown out from their original site.
• These are the most common of non invasive breast cancer and are
easier to treat
•
What causes breast cancer
• The exact reason why a cell becomes cancerous is unclear.
• It is thought that something damages or alters certain genes in the
cell.
This makes the cell abnormal and multiply out of control.
Risk factors for breast cancer
• Age -risk doubles every 10 years of age
• Where you live- this may reflect genetic or environmental factors.
• Family history- close relatives who have or have had breast cancer
< 50 years when diagnosed.
• If you have had a previous breast cancer.
• Being childless, or if you had your first child after the age of thirty.
• Not having breast-fed your children.
Risk factors for breast cancer
• Early age of starting periods.
• Chest being exposed to radiation.
• Having a menopause over the age of 55.
• Taking continuous combined hormone replacement therapy (HRT)
for several years (in women over 50 years), leading to a slightly
increased risk.
• Excess alcohol
Family history and genetic testing
• About 1 in 20 cases of breast cancer are caused by a faulty gene
which can be inherited.
• The genes BRCA1 and BRCA2 are the most common faulty genes
• See your doctor if strong family history
What are the symptoms of breast cancer
•
a painless lump in the breast
Note: most breast lumps are not cancerous, mostly (cysts or
fibroadenomas (a clumping of glandular tissue) which are benign.
•
Changes in the size or shape of a breast.
•
Dimpling or thickening of some of the skin on a part of a breast.
•
The nipple becoming inverted (turning in).
•
A discharge occurring from a nipple (which may be bloodstained).
•
A rare type of breast cancer, causing a rash around the nipple, which can
look similar to a small patch of eczema.
•
Pain in a breast. Note: pain is not a usual early symptom. Many women
develop painful breasts (mastalgia) and this is not usually caused by cancer.
So what happens if find you lump
• Go to the doctor- (examination of breasts and armpits)
• You will normally be referred to a specialist. The following tests are
usually done:
• Mammogram-This is a special X-ray of the breast tissue.
• Ultrasound sound of the breast.
• MRI scan of the breast. This is more commonly performed on
younger women, who may have denser breast tissue.
• Biopsy- to confirm the diagnosis
• Staging to assess extent of disease
Treatment of breast cancer
• Surgery
• Chemotherapy
• Radiotherapy
• Hormone treatment
• Often a combination of two or more of these treatments is used.
Surgery
Radiotherapy
• Radiotherapy is a treatment which uses high-energy beams of
radiation which are focused on cancerous tissue. This kills cancer
cells, or stops cancer cells from multiplying.
For breast cancer, radiotherapy is mainly used in addition to
surgery- adjuvant radiotherapy
Hormones
• Some types of breast cancer are affected by the female hormones
oestrogen and progesterone.
• These hormones stimulate the cancer cells to divide and multiply.
Treatments which reduce the level of these hormones, or prevent
them from working, are commonly used in people with breast
cancer.
An example is
It works by blocking the oestrogen from working on cells. It is usually
taken for five years
Who has breast screening
• all women aged 50-70 years in the UK are offered a routine breast
screening test every three years. (The government is planning to
extend the age range for routine breast screening from age 47 to 73
by 2012.
• If you are under the age of 50 (or 47 from 2012), routine breast
screening is not currently available unless:
-You have had breast cancer in the past.
-You have a first-degree relative (mother or sister) who has had
breast cancer at a young age.
-You are known to have a gene which makes you more prone to
breast cancer
How is breast screening done
Does breast screening save lives?
• Research studies have shown that breast screening has significantly
reduced the number of deaths from breast cancer by 35% in women
who are screened regularly with mammography.
Statistics also show that the NHS Breast Screening Programme
saves about 1,400 lives every year in England.
Take home message
• A lot of breast cancers are detected early by breast screening.
• However, a small number are not- check your breasts!
• All women of every age should still remain breast aware. That is, get
to know how your breasts and nipples normally look and feel, and
any changes that occur before and after your periods.
•
See your GP if you notice any changes, lumps, or other
abnormalities in your breasts or nipples. Don't just wait until your
next screening mammography.
• Attend your breast screening appointments
• If you move area, ensure you tell GP so screening remains up to
date
