Colorectal cancer is a malignancy that affects the colon and / or rectum, affecting the intestinal wall, and depending on the degree of invasion that may compromise other organs, either directly or through metastasis. This type of cancer is the most frequent, and generally is related to physical inactivity, obesity, smoking, family history of colorectal cancer, genetic predisposition, diet rich in red meat, and possibly the diet low in fiber.
This type of cancer includes tumors throughout the colon, rectum and appendix. Approximately 655 000 people per year die from this cancer, the third most common form of cancer and the second leading cause of death in the Western world. [1] It is believed that many tumors arise from adenomatous polyps in the colon. These polyps are generally benign, but can develop into malignant tumors over time. In most cases, the diagnosis of colorectal cancer is through colonoscopy.
Treatment consists of removing the tumor, which can be endoscopy (colonoscopy) or surgical. The endoscopic resection is performed in cases of early cancer, or those where there was a more profound impairment of the gut wall. In surgical cases, compromised the intestinal segment is resected and reconstructed intestinal transit whenever possible. Furthermore, there may be the need for additional treatment with chemotherapy and radiotherapy, which are stated before or after surgery, and in more severe cases, in order to prevent or treat metastatic lesions.
Treatment
Surgery is the initial treatment, removing the affected part of the bowel and lymph nodes (small structures that are part of the immune system) near region. Then, radiotherapy, with or without chemotherapy is used to reduce the possibility of surrounding the tumor.
Treatment depends primarily on the size, location and extent of the tumor. When the disease is spread, with metastases to the liver, lungs or other organs, the chances of cure are reduced.
Prevention
A diet rich in vegetables and dairy products and low in fat (especially saturated), besides doing regular physical activity prevent colorectal cancer. You should avoid excessive consumption of red meat. Some factors increase the risk of developing the disease, such as age over 50, family history of colorectal cancer, personal history of the disease (having had ovarian cancer, uterine or breast cancer), low calcium intake, and obesity and sedentary lifestyle .
Are also risk factors inflammatory bowel diseases, such as chronic ulcerative colitis and Crohn's disease, and hereditary diseases, such as familial adenomatous polyposis (FAP) and hereditary nonpolyposis colorectal cancer (HNPCC).
