There are several Stages of Colorectal Cancer, which refer to its progression from the initial stage of adenocarcinoma to the later stages. Stage 0 means the cancer is located in the rectum or colon and has not spread outside of the body. Stage 1 is when the cancer has only invaded the colon walls, but not spread to nearby lymph nodes or other organs. Stage 2 means the cancer has spread to nearby organs, and Stage 3 is when the cancer has metastasized to distant organs.

While many types of cancer start in the colon, this type of cancer is a serious condition. Early detection is crucial for the cancer to be curable. Screening is recommended for anyone over the age of 45 to prevent it from developing. Regular physical activity, eating fruits and vegetables, wheat bran, and avoiding processed meat are just some of the lifestyle changes that can help prevent colon cancer. Additionally, avoiding excessive amounts of fat, alcohol, and cigarettes may reduce your risk of developing colorectal cancer.

Colorectal cancer symptoms can be mild or nonexistent in the early stages. Depending on where the cancer has spread, these symptoms can be mistaken for other conditions, such as infection or hemorrhoids. If you suspect any of these symptoms, you should see your healthcare provider. Your provider will ask you about your overall health, including your risk factors and family history. Your doctor will perform a physical exam to check for signs of the disease.

Patients with a suspected diagnosis of colorectal cancer may be recommended to undergo a biopsy. In early stages, a polyp or suspicious area of the colon may be removed and analyzed under a microscope. If a polyp is detected, the tissue sample may also undergo gene testing and other tests. However, the results from the test will help determine the stage of the cancer and what type of treatment to pursue.

The screening tests for colorectal cancer are an effective way to detect the condition before symptoms develop. The sooner the cancer is detected, the better. Typically, colorectal cancer screenings start at age 45 for people of average risk. For people at a higher risk, it may begin earlier. If the cancer is detected in the early stages, it may be more easily treated and the disease will not spread.
