Colorectal carcinoma is a type of cancer that develops in the large intestine, rectum, or colon. It is the third most common cancer worldwide, with an estimated 1.4 million new cases diagnosed each year.
Colorectal carcinoma is characterized by the presence of abnormal cells in the colon or rectum. These cells often have an abnormal appearance and behave differently than normal cells. The cells can also spread to other parts of the body through a process called metastasis.
