and factors
👉Family history: A person’s risk doubles if a direct relative has previously had the disease. There is an even greater risk if more than one relative has had colorectal cancer.
👉Genetics: Individuals with inherited disorders such as familial adenomatous polyposis (FAP), where an individual is prone to polyp formation, have a higher risk of developing colorectal cancer.
👉Colorectal polyps or inflammatory bowel diseases: A history of polyps or inflammatory bowel disease, where the bowel is inflamed for many years, increases the risk of colorectal cancer.
👉Age: Although a person can develop colorectal cancer at any age, the risk increases greatly with age. Over 90% of colorectal cases are diagnosed in patients over the age of 50.
👉Lifestyle: A sedentary lifestyle is associated with a higher risk of colorectal cancer. Studies have also linked obesity, lack of exercise, smoking and excessive alcohol consumption to a greater risk of colorectal cancer.
👉Potential protective agents: Non-steroidal anti-inflammatory drugs (NSAIDs), such as aspirin, have been associated with a reduced risk of colorectal cancer. A healthy, fibre containing diet and hormone replacement therapy in women are also possible protective factors.
