Initially, the symptoms of colorectal cancer may not be apparent until the cancer has spread throughout the colon. For a definitive diagnosis, a healthcare provider will perform several tests. This will involve asking questions about your medical history, any symptoms you may have experienced, and any family members you know who have had this disease. They will also conduct a physical examination to identify any signs and symptoms of colorectal cancer.

While there are no specific colorectal cancer symptoms, patients may experience rectal bleeding or other signs that are similar to hemorrhoids, ulcerative colitis, or other GI issues. The symptoms of colorectal cancer should never be ignored, as they may be caused by other illnesses. In fact, they could be caused by an underlying medical condition like Crohn’s disease, ulcerative colitis, or other GI problems.

After detecting the disease, patients may undergo treatment. The treatments for colorectal cancer depend on its stage. For stage 0 cancer, a colonoscopy is often enough. Stages I and II will require more complex surgeries such as colon resection. If stage 3 is present, a colostomy is required. This procedure is required if the cancer has spread beyond the colon.

There are four stages of the disease. Stage 0 is also known as carcinoma in situ and refers to a type of cancer that has not spread beyond the inner layer of the colon. Stage 1 cancer is not yet large and has not spread to nearby lymph nodes. Stage 2 is more advanced than stage 0 and may have spread to distant organs. However, the good news is that in stage 0, the cancer has not spread yet.

A cancerous cell in the colon starts out as a precancerous polyp. The cancerous cells multiply by dividing uncontrollably, accumulating in the colon. This growth continues to feed the tumor, which can invade normal tissue. The cancerous cells may also travel to other parts of the body, resulting in its symptoms. The symptoms of colorectal cancer include pain, bleeding and a bowel obstruction.

Early detection of colorectal cancer is vital for prevention. Screening tests can detect early cancers, when they’re much more treatable. In general, colorectal cancer screening should begin at age 45, but older individuals may be recommended to have regular exams. If you’re at an increased risk for colorectal cancer, your doctor may recommend screening sooner than 45. You’ll also need to undergo regular tests if you have certain conditions.
