Surgery is the Basic and Best Treatment of Colon-rectum CancerBY: Ritu Choudhary | Category: Colon and Rectal Cancer | Submitted: 2011-02-20 11:55:38
Cancers of the colon-rectum is about 20% of all cancers. They occur most often after reaching their fifties and so nearly equal among man and woman. Most of these cancers results from the degeneration of benign tumors, called polyps and some of these cancers are hereditary, due to transmission of genes susceptible to cancer. Screening therefore relates apparently healthy subjects. There are two situations where this screening is imperative: where there is family history of polyps, especially if these polyps appear to be hereditary and where there is family history of cancer of the large intestine. To perform the screening, two examinations are essential: Digital rectal exam and Colonoscopy. Any presence of blood in the stool, however small is sufficient to consult your doctor because only they will indeed be able to specify whether the bleeding is related to an early cancer, or a single break of hemorrhoids. In reality, this bleeding will be most unexpected indicative of cancer if it is painless, it is found to be in contact with stool. Once you've seen these symptoms, you should therefore consult your doctor immediately. Fatigue, fever, weight loss, anemia, abdominal pain or obstruction, which are symptoms reveal more advanced cancer. Colonoscopy is the best method to detect colon cancer. Here gastroentologist first introduces the colonoscope as far as possible, and then gradually visualizes the entire colonic mucosa. Once the cancer is diagnosed, the basic treatment of cancer of the colon rectum is surgery. When the tumor is headquarters on the colon, segmental colectomy is most often performed, depending on the case, the rectosigmoid, the left colon, the transverse colon or right colon (ascending), including the cecum and the most distal small intestine. However, in some cases, if the tumor is large, surgeon may achieve greater intervention, called hemicolectomy, which involves the removal of the right side or left side of your large intestine, and may even extend the removal of other affected abdominal organs. When the cancer site is located on the rectum, two types of intervention are possible: rectosigmoidectomy if the cancer is located high enough, ie far from the anus or an amputation abdominoperinale if located below, ie close to the anus. The need for adjuvant chemotherapy after surgery is thus required in two circumstances: when the tumor has invaded the wall of the large intestine and when accompanied by lymph node disease. Most often it is 6 to 12 months. There are advanced cancer cases where unfortunately the disease is detected late and is proving to be evolved. There are two main situations to consider: cancer is locally advanced or it has already spread to the liver. In locally, tumor is so large that one can readily make ablation. Your surgeon will then propose an intervention to discharge, comprising a first step in the realization of an artificial anus. The objective here is to put to rest the colon where the tumor seat and disinfected to eradicate the tumor in a second time. In a third step, if possible, the goal is a restoration of the continuity of large intestine, removing the artificial anus. There is evidence that cancers of the colon are favored by a high calorie diet, consisting of excessive consumption of red meat and animal fat, and conversely, inadequate fruit and vegetables. The carcinogenic role of such imbalances regime is recognized. Thus primary prevention is to balance meals, consuming fruits and vegetables in sufficient quantity, and restricting red meat and animal fat. It is advisable to replace butter with vegetable oil, and limit consumption of fatty cheeses.
