According to the National Cancer Institute colon cancer is the third most common cancer in men. The majority of colon cancer cases arise from adenomatous polyps-clusters of abnormal cells in the glands covering the inner wall of the colon.
Over time these abnormal growths enlarge and ultimately degenerate to become adenocaricinomas tumours.
Symptoms of colon cancer include:
Unexplained weight loss
Change in frequency or character of stool
Unexplained, persistent nausea or vomiting
Sensation of incomplete evacuation after a bowel movement
Treatments for colon cancer may vary depending on how advanced the cancer is. The primary treatment for colon cancer is to surgically remove part or all of the colon. Other treatments include chemotherapy and radiation. The survival rate for those with colon cancer depends on how advanced the cancer is and whether or not it has spread to nearby organs.
