Hyperplastic Polyp(s): Hyperplastic polyps are not an uncommon polyp, and are often routinely
found during colonoscopy screenings. Most evidence indicates that hyperplastic polyps are not
generally associated with colorectal cancer. Hyperplastic polyps are thought to be truly benign
growths, possessing no potential for progression to colorectal cancer. The likelihood that
hyperplastic polyps will become cancer is very low.
Adenomatous Polyp(s): Adenomatous polyps are a common type. They are gland-like growths
that develop on the mucous membrane that lines the large intestine. These polyps are not
malignant themselves, but have the potential to become cancerous if undetected or ignored.
Tubulovillous Adenoma: Tubulovillous Adenoma (TVA) is a type of polyp that grows in
the colon and other places in the gastrointestinal tract. These adenomas are polyps that display a
combination of tubular and villous growth patterns and may become malignant (cancerous).
Right-Sided Hyperplastic Polyp: Also referred to as Sessile Serrated Adenoma (SSA) or
Sessile Serrated Polyps (SSP). This is a premalignant flat (or sessile) lesion of the colon,
predominantly seen in the cecum and ascending colon. SSA is generally recognized to be a
precursor of colorectal cancer.
Diverticulosis: Diverticulosis is a condition in which there are small pouches or pockets in the
wall or lining of any portion of the digestive tract. These pockets occur when the inner layer of
the digestive tract pushes through weak spots in the outer layer. A single pouch is called a
diverticulum. The pouches associated with diverticulosis are most often located in the lower part
of the large intestine (the colon). Some people may have only several small pouches on the left
side of the colon, while others may have involvement in most of the colon.
Hemorrhoids: Hemorrhoids are cushions of swollen tissue and blood vessels in the lower rectal
area. Hemorrhoids are classified as either “internal” or “external.” External hemorrhoids can
cause itching, swelling, and pain, whereas internal hemorrhoids can cause bleeding, itching,
swelling, and eventually prolapse (loose tissue that bulges outside of the anus). Hemorrhoids can
be caused by a number of things, including constipation, straining, pregnancy, etc., and can be
unpleasant if left untreated.
