Information about Colorectal Cancer

Colon or colorectal cancer is the cancer of the colon, the last part of the vertebrate digestive system. It begins with the indefinite expansion of the epithelial cells, the inner surface of the intestine. The colon in most mammals is the last part of the gastrointestinal tract. Its main task is to keep water and other materials from solid waste before it eliminated from the body.

It was noted the majority of cases with colorectal polyps, the hyperplastic masses started. But these little balloons structures can have a number of changes in elementary subjected tumors (eg, tubular adenoma), and finally tumor metastasis (for example) with colorectal adenocarcinoma growth.

For many years, cancer remains one of the cancers diagnosed regularly throughout the world hundreds of thousands of newly diagnosed cases per year. The increased> Incidence of cancer is often accompanied by a high mortality. Colorectal cancer is a leading cause of cancer deaths worldwide.

There are a variety of risk factors associated dvelopment of colon cancer. Age is one of them. Cancer risk increases proportionally with age. And men form a group with a higher risk than women. Another group with high risk of developing colon cancer are people with personal or family historyof hereditary genetic mutations (HNPCC: Hereditary nonpolyposis colorectal cancer and FAP: Familial adenomatous polyposis). People with chronic inflammatory bowel disease have a greater risk of developing colon cancer as well.

Other important risk factors include obesity, extreme consumption of red meat, high fat diet, nutrition, low calcium, vitamin D, selenium and folic acid, inadequate intake of fruits and vegetables, lack of exercise, smoking and aging of the immune systemSystem. Conversely, studies have found that non-steroidal anti-can-inflammatory drugs (NSAIDs) such as aspirin and ibuprofen, estrogen-containing medications and cholesterol-lowering drugs protect against colon cancer. These drugs are not approved but at this point in time as an alternative prevention.

While some symptoms, the presence of this cancer may indicate that many of these symptoms clearly not attributable colon cancer and are, in fact,analogous to other common diseases and illnesses. These symptoms may or may may suddenly grow piece by piece over time. Symptoms include changes in bowel movements, continuous diarrhea, constipation, total intestinal blockage () in extreme pain, bloody stools, abdominal cramps and sudden, or chronic pain, only to to name a few.

Surgery is still the most effective treatment if the tumor is not invasive and metastasize. Thiseffected by the removal of the tumor along with part of the normal colon tissue and adjacent lymph nodes.

Other types of treatments including chemotherapy, radiotherapy and immunotherapy. Individual or combinatorial therapy can take place depending on the physical condition of the patient and stage of disease.
