Understanding Your Colon How Does Colorectal Cancer Develop Colon cancer typically affects older adults, though it can happen at any age. it usually begins as small clumps of cells called polyps that form inside the colon. Learn where colorectal cancer starts, ways to prevent it, tests to diagnose it, the options for treatment, and what to do after you have finished treatment.
Colorectal Cancer Shanks Surgery Colorectal cancer happens when there are changes in your genetic material (dna). these changes are also called mutations or variants. often, the genetic changes that lead to colorectal cancer happen during your lifetime and the exact cause is unknown. Colon cancer happens when genetic mutations turn healthy colon cells into cancerous cells. the cancerous cells divide and multiply to make cancerous colon polyps. over time, cancer grows through the layers of muscle and tissue that make up your colon wall. Most colorectal cancers develop from polyps in glandular tissue of the intestinal lining. most polyps are benign, but at least one type is known to be precancerous. these are called. Sometimes abnormal growths, called polyps, form in the colon or rectum. over time, some polyps may turn into cancer. screening tests can find polyps so they can be removed before turning into cancer. screening also helps find colorectal cancer at an early stage, when treatment works best.

There are three main pathways for the development of colorectal cancer: conventional, which accounts for 70% of colorectal cancer. this pathway results from an accumulation of genetic damage to the cells lining the large intestine. tumour suppressor genes are affected, like apc, kras, p53. Colorectal cancer starts as a polyp, a growth, on the inner lining of the colon or rectum. polyps are common, especially as we age, and most are noncancerous. some polyps, however, can turn into cancer over time, forming cancer cells in the wall of the colon or rectum, where they can grow into blood vessels that can spread to other parts of the. Most colorectal cancers develop from small growths called polyps, which arise from the inner lining of the colon or rectum. while most polyps are benign (non cancerous), certain types—especially adenomatous polyps (adenomas)—can gradually transform into cancer over many years. Colorectal cancer (crc) ranks second among the most common types of cancer in terms of mortality worldwide. this type of cancer arises from mutations in the colonic and rectal epithelial tissues that target oncogenes, tumor suppressor genes and genes related to dna repair mechanisms.
