When a cancerous growth originates in the colon and then spreads to the rectum, it leads to colorectal cancer. It is the second most common form of cancer in the western world. The risk of colorectal cancer is higher after the age of fifty years. Experts have suggested that smoking, fat-rich diet, Crohn’s disease and colitis are some of the risk factors for this disease.
The symptoms of colorectal cancer include bowel disorder (diarrhea or constipation), abdominal heaviness, bloody stool, bloating, abdominal cramps, nausea, vomiting, weight loss and tiredness. Diagnostic test like colonoscopy helps diagnose the severity of such a condition. For treatment of colorectal cancer, surgery (if detected in early stage), chemotherapy, radiation therapy and sometimes combination therapy are mostly recommended.
