Proper Care Needed To Diagnose Colorectal Cancer
Colorectal cancer (also called as colon cancer or large bowel cancer) starts in either the colon or the rectum. This particular cancer includes cancerous growths in the colon, rectum and appendix. It arises from adenomatous polyps in the colon, lower part of the digestive system. Colon cancer and rectal cancer have many features in common. And together they are often referred as colorectal cancer. In most of the cases it begins as small, noncancerous clumps of cells called adenomatous clumps. Over a period of time these polyps become colon cancers. Localized colon cancer is usually diagnosed through colonoscopy.
There are certain symptoms of the colorectal cancer that largely depend on the location of tumor in bowel and its affect elsewhere in the body. Its symptoms include fatigue, weakness, change in bowel habits, shortness of breath, narrow stools, diarrhea or constipation, abdominal pain, weight loss, cramp, etc. The symptoms and signs are divided into local, constitutional and metastatic. Some other conditions like irritable bowel syndrome, ulcerative colitis, diverticulosis and peptic ulcer disease can have symptoms of colorectal cancer.
As far as the treatment is concern, early detection of colorectal cancer greatly improves the chance of a cure. There are several tests available such as digital rectal exam (DRE), fecal occult blood test (FOBT), Endoscopy, Sigmoidoscopy, colonoscopy. Its treatment depends on the staging of the cancer. Surgery is the primary treatment for colorectal cancer, while chemotherapy and radiotherapy can be performed on the individual patient’s staging and other medical factors.
