Colorectal cancer is a neoplastic disease of the large intestine from Ileo-cecal junction till the rectum. Unregulated growth of their cell lining lead to polyps and cancers.
The exact cause of colorectal cancer is not known, but several factors can increase risk of developing colorectal cancer.
Age: Elderly people are at risk of colorectal cancer. It is most common in people over 50 years of age.
Family history: People with history of colorectal cancer in family (first degree relatives) are at increased risk.
Genetic factors: They are associated with some hereditary syndromes like lynch syndrome, familial Adenomatous polyposis, etc.
Lifestyle factors: A diet rich in red and processed meats and low in fibres or lacking fruits and vegetables can increase risk of colon cancer. Obesity, reduced physical activity, alcohol consumption or smoking also increase risk of colorectal cancer.
Medical Conditions: Certain medical conditions like inflammatory bowel disease (Crohn’s disease and ulcerative colitis) can increase the risk of colorectal cancer.
It is important to note that having one or more risk factors does not mean that a person will develop cancer. Regular screening tests such as stool occult blood and colonoscopy, can help to detect as well as prevent it at the early stage.
