Colorectal cancer, also called large bowel cancer, is the term used to reveal malignant tumors found in the colon and rectum.
In the United States, about 160,000 new cases of colorectal cancer are diagnosed each year. It is the third most commonly diagnosed cancer and the second foremost cause of cancer death in the United States.
The median age of analysis of cancer in patients with this syndrome is 44 years old, as compared to 64 years old in population without the syndrome. Two-thirds of these cancers occur in the proximal colon.
In colon cancer patients, pathologists can quantum microsatellite instability in colon tumor specimens, which is a surrogate ticket for Dna mismatch mend gene dysfunction.
To know if you are at risk to colorectal cancer, you must know what are the causes, risk factors and symptoms associated with this cancer.
However, I have known there is no single cause for colon cancer. Nearly all colon cancers begin as benign polyps, which gradually found into cancer.
But you have a higher risk for colon cancer if you have: Colorectal polyps Cancer elsewhere in the body, a family history of colon cancer, ulcerative colitis, Crohn's disease, personal history of breast cancer.
Certain genetic syndromes also growth the risk of developing colon cancer. What you eat may play a role in your risk of colon cancer.
Colon cancer may be associated with a high-fat, low-fiber diet and red meat. Colon and rectum cancer often causes no symptoms, especially at first.
Symptoms
The following symptoms, however, may indicate colon cancer: Diarrhea, constipation, or other convert in bowel habits, blood in the stool, unexplained anemia, abdominal pain and tenderness in the lower abdomen. It may also comprise intestinal obstruction, weight loss with no known reason, narrow stools.
Diagnosis
With allowable screening, colon cancer can be detected Before the amelioration of symptoms, when it is most curable.
A rectal exam may reveal a mass in patients with rectal cancer, but not colon cancer. Imaging tests to diagnose colorectal cancer include: Colonoscopy and Sigmoidoscopy.
If your physician learns that you do have colorectal cancer, additional tests will be done to see if the cancer has spread.
Stages
¨ Stage 0: Very early cancer on the innermost layer of the intestine Stage I: Cancer is in the inner layers of the colon
¨ Stage Ii: Cancer has spread through the muscle wall of the colon
¨ Stage Iii: Cancer has spread to the lymph nodes
¨ Stage Iv: Cancer that has spread to other organs.
Treatment depends partly on the stage of the cancer. In general, treatments may include: Chemotherapy medicines to kill cancer cells; surgical operation to take off cancer cells; Radiation therapy to destroy cancerous tissue.
Stage 0 colon cancer may be treated by removing the cancer cells, often during a colonoscopy; Stage Ii to stage Iv colon cancer should receive chemotherapy after surgical operation and this may comprise cutting out the cancer, burning it (ablation), or frosty it (cryotherapy); Stages I, Ii, and Iii cancer are carefully potentially curable but in most cases, stage Iv cancer is not curable.
Prevention
Some evidence suggests that low-fat and high-fiber diets may sell out your risk of colon cancer. Preventive Services Task Force recommends against taking aspirin or other anti-inflammatory medicines to preclude colon cancer if you have an median risk of the disease -- even if man in your family has had the condition.
Although low-dose aspirin may help sell out your risk of other conditions, such as heart disease, it does not lower the rate of colon cancer.
