**4. Colorectal Cancer**

The name "colorectal cancer" is used to describe bowel cancer that starts in the colon or the rectum. CRC almost always develops from growths called colorectal polyps that form in the lining of the colon (adenocarcinoma in more than 95% of cases) [22,31]. After the diagnosis, the treatment depends on various factors, including the stage of cancer. In the early stages of CRC, the tumor just needs to be surgically removed, but in advanced stages, additional treatments may be considered, such as chemotherapy and radiation therapy, among other adjuvant therapies [31].

As mentioned above, CRC treatment depends on cancer staging, but it is classified into two groups, surgery and adjuvant therapy.
