Corporate PartnershipsMutually Beneficial Relationships · Bowel Cancer Most bowel cancers start as benign, non-threatening growths – called polyps – on the wall The risk of developing bowel cancer rises sharply and progressively from age Patients with cancer of the rectum may present with a change in bowel. Polyps may be small and produce few, if any, symptoms. For this Association between diet and increased colon cancer risk. Studies of large. Virtually all colon cancer develops from adenomatous polyps in the colon, Polyps don't always become cancerous, but your risk of developing cancer increases with the number and size of What is sporadic colon cancer?.

This form of the syndrome also has an increased risk for brain tumours, specifically medulloblastoma. MYH-associated polyposis, or MAP, is an inherited condition that increases the risk of colorectal cancer.

People with MAP develop many adenomatous polyps in the inner lining, or mucosa, of the colon. Juvenile polyposis syndrome is an inherited condition that causes hamartomas to develop. Hamartomas are usually a non-cancerous benign type of polyp, but they have the potential to develop into cancer. People with Peutz-Jeghers syndrome often develop hamartomas in the digestive tract.

They also tend to develop dark blue or brown freckles that are most common on the face, fingers and toes and inside of the mouth. Peutz-Jeghers syndrome is also associated with a higher than average risk of developing other types of cancers including breast, pancreatic, stomach, ovarian, lung and small intestine cancers.

Hereditary mixed polyposis syndrome HMPS is an inherited condition that causes many different types of polyps to grow. The most common type of polyp to grow is a hamartoma. Cowden syndrome and Bannayan-Riley-Ruvalcaba syndrome are rare genetic conditions and part of a group of disorders that have a mutation in the tumour suppressor gene PTEN. People with a PTEN mutation are at an increased risk of developing benign and cancerous tumours, including colorectal cancer.

Back to top Not being physically active People who are not physically active are at a higher risk for developing colorectal cancer. You can lower your risk by becoming more active. Back to top Being overweight or obese Colorectal cancer occurs more often in people who are overweight or obese than in those who have a healthy weight. Having a higher body mass index BMI increases the risk in both men and women, although men seem to be most at risk.

Back to top Alcohol Drinking 50 g about 3. Alcohol increases the risk for both men and women, but the effect appears to be stronger for men.

Risk factors for colorectal cancer

Back to top Smoking Smoking tobacco increases the risk of developing colorectal cancer. Researchers think that it may take a long time perhaps up to 20 years for colorectal cancer to develop due to smoking.

It appears that the risk increases with both the length of time a person smokes and the amount smoked. Back to top Eating a diet high in red meat Eating a diet high in red meat beef, pork, lamb and goat increases the risk of developing colorectal cancer. Eating red meat has also been shown to increase the risk of dying from colorectal cancer.

Back to top Eating processed meats Processed meats are meats preserved by smoking, curing, salting or adding preservatives such as nitrates or nitrites.

Eating processed meats increases the risk of developing colorectal cancer, and the risk increases with the amount eaten. It has also been shown to increase the risk of dying from cancer. Back to top Diet low in fibre Eating a diet low in fibre increases the risk of colorectal cancer. The evidence shows that eating foods containing dietary fibre protects against colorectal cancer.

Back to top Sedentary behaviour Higher amounts of sedentary behaviour sitting for long periods of time have been linked to an increased risk for colorectal cancer, particularly cancer in the distal colon and rectum.

What are the risk factors for polyps? There are a few risk factors that can lead to the formation of polyps and, if undetected or untreated, cancer of the colon. Age The risk of colon polyps is greater in people over 50 years of age, as statistics have revealed greater numbers of patients over Race It has been found that those of African American origin are at a greater risk of developing cancer of the colon.

Family history If a parent, child, or sibling in a family has colon polyps, the chances of developing polyps are high in the other family members.

In case several family members suffer from polyps, the chances increase greatly. However, in some cases of colon polyps, no hereditary connection was found. In cases of uncontrolled diabetes, the risk of developing polyps increases. Use of alcohol and tobacco is also considered a risk factor for polyps.

Lack of exercise and obesity The chances of polyps developing in the colon increase in case of obesity and lack of physical exercise. These syndromes include familial adenomatous polyposis and hereditary nonpolyposis colorectal cancer, which is also known as Lynch syndrome.

Family history of colon cancer. You're more likely to develop colon cancer if you have a parent, sibling or child with the disease. If more than one family member has colon cancer or rectal cancer, your risk is even greater.

Colon cancer and rectal cancer may be associated with a diet low in fiber and high in fat and calories. Research in this area has had mixed results. Some studies have found an increased risk of colon cancer in people who eat diets high in red meat and processed meat.

Factors that Increase Risk of Colon Polyps

If you're inactive, you're more likely to develop colon cancer. Getting regular physical activity may reduce your risk of colon cancer. People with diabetes and insulin resistance have an increased risk of colon cancer. People who are obese have an increased risk of colon cancer and an increased risk of dying of colon cancer when compared with people considered normal weight.

People who smoke may have an increased risk of colon cancer. Heavy use of alcohol increases your risk of colon cancer. Radiation therapy for cancer.

Radiation therapy directed at the abdomen to treat previous cancers increases the risk of colon and rectal cancer. Prevention Get screened for colon cancer People with an average risk of colon cancer can consider screening beginning at age But people with an increased risk, such as those with a family history of colon cancer, should consider screening sooner.

Several screening options exist — each with its own benefits and drawbacks. Talk about your options with your doctor, and together you can decide which tests are appropriate for you. Make lifestyle changes to reduce your risk You can take steps to reduce your risk of colon cancer by making changes in your everyday life. Eat a variety of fruits, vegetables and whole grains. Fruits, vegetables and whole grains contain vitamins, minerals, fiber and antioxidants, which may play a role in cancer prevention.
