Colon cancer is a disease of the large intestine (colon), the lower part of your digestive system. Colorectal cancer, more commonly known as colon cancer, is one of the more common types of cancer - it's the third most common and the second most lethal. Most cases of colon cancer begin as small, noncancerous (benign) clumps of cells called adenomatous polyps. Over time, some of these polyps may become cancerous. (Mayo Clinic).
Polyps can be small and produce few, if any, symptoms. For this reason, doctors recommend regular screening tests which help prevent the cancer by identifying polyps before they become malignant.
Signs and symptoms of colon cancer include: .
-a change in bowel habits, including diarrhea or constipation.
-change in stool consistency.
-rectal bleeding or blood in your stool persistent.
-abdominal discomfort: cramps, gas or pain.
-a feeling that your bowel isn't completely empty.
-weakness or fatigue.
-unexplained weight loss.
Symptoms of colon cancer can take a while to detect but if it's detected early, survival and recovery is likely. Unfortunately, symptoms of colon cancer often don't appear until the late stages of the disease. (Mayo Clinic).
There are many people who have colon cancer and do not even know, because they do not experience any symptoms in the early stages of the disease. When symptoms appear, they are likely to vary, depending on the cancer's size and location in your large intestine.
Pathophysiology of Colon Cancer.
Colon cancer is the second leading cause of deaths. Every year, approximately 48,000 people die in the U.S. from colon cancer. Many of these deaths could have be prevented if patients would only visit their doctor regularly to be tested and get the early detection and treatment through routine colon cancer screening.
Colon Cancer Progresses through stages and the stage of the cancer determines the appropriate treatment and the patient's relative 5-year survival rate which is the average percentage of colon cancer patients.
