Question 3 Not yet graded / 1 pts Exercise 1 - Question 3 How does the removal of polyps help to prevent colorectal cancer? ( Hint : Describe the relationship between polyps and cancer development.) Your Answer: Polyps in the intestinal tract ae small growths covered with mucosa and are attached to the surface of the intestine. Although most are benign, they are significant because some have the potential to become malignant. Polyps can be classified as adenomatous, malignant, or hyperplastic. Hyperplastic polyps have a little chance of becoming cancerous; whereas adenomas have the potential to become malignant. A very small number of adenomas progress to cancer; almost all colorectal cancer develops from an adenoma. Adenomas are further classified as villous or tubular. Of these, villous adenomas pose a greater cancer risk. malignant polyps are those that contain cancerous cells when they are discovered. Most colorectal cancers are adenocarcinomas, which are tumors that arise from the glandular epithelial tissue of the colon. They develop as a multi-step process, resulting in a number of molecular changes, such as loss of key tumor suppressor genes and activation of certain oncogenes that alter colonic mucosa cell division. The increased proliferation of the colonic mucosa forms polyps that can transform into malignant tumors. Hence, the removal of the polyp will prevent it from progressing into colorectal cancer.
