The main cause of colorectal cancer is not known with certainty, but there are several things that can increase a person’s risk of experiencing colorectal cancer cell growth that can be altered or irreversible.
Factors that can be changed
There are several causes of colorectal cancer that are influenced by lifestyle, including:
1, Being overweight – obesity can increase the risk of cancer cell growth and increase the risk of death from cancer. The risk of getting cancer is because obesity is greater in men than in women.
2. Lack of physical activity – people who lack physical activity will be more susceptible to cancer, including colorectal cancer.
3. Diet – known patterns of high consumption of red meat and processed meat can increase the risk of colorectal cancer. In addition, cooking meat with high temperatures causes an increase in a chemical compound that triggers cancer in the intestine. While a healthy diet by consuming vegetables, fruits and whole grains is known to reduce the risk of cancer.
4. Smoking – smoking behavior is known as a risk factor for various cancers including colorectal cancer. The longer smoking time, the greater the risk of colorectal cancer.
5. Alcoholic drinks – consuming too many types of alcoholic beverages will increase the risk of colorectal cancer. Restrictions to reducing consumption of alcoholic beverages will reduce the risk of colorectal cancer.
Causes that cannot be changed
There are several irreversible risk factors to reduce the risk of colorectal cancer, namely:
1. Old age – over 50 years of age will increase the risk of getting cancer. Cancer takes time to develop from abnormal cells, so that individuals will be diagnosed with cancer in old age.
2. History of suffering from polyp or colorectal cancer – someone who has been declared cured of colorectal cancer or polyps can experience the growth of new cancer cells in the intestine. This risk will be greater if someone has been exposed to colorectal cancer at a young age.
3. Have experienced inflammatory bowel disease (IBD), aka inflammatory bowel disease – this is an inflammatory condition in the large intestine that lasts a long time. The intestinal wall of IBD sufferers experiences the appearance of abnormal cells that can be seen with a microscope (dysplasia). If you have been diagnosed with IBD, do colorectal cancer screening regularly. IBD is different from inflammatory bowel syndrome (IBS) which does not increase the risk of colorectal cancer.
4. Family history of adenomatous colorectal and familial cancer polyps – the risk of colorectal cancer will be higher if there is one of the parents, blood relatives, or child who has colorectal cancer. A person’s risk will be higher if one family member has had colorectal cancer under the age of 45 years. Cancer conditions can be inherited in one family due to genetic factors or affected by environmental factors or interaction between the two. Although most sufferers do not have a family history of this disease, but with a family history will increase the risk of 20% of colorectal cancer. Similarly, a family history of developing cancerous polyps, adenomatous polyps. If there are family members who experience it, do colorectal cancer detection regularly.
5. Having type 2 diabetes – someone who has type 2 diabetes has a higher risk of colorectal cancer. Both diabetes or colorectal cancer have many similar risk factors such as obesity. Although it does not have other risk factors, someone with diabetes has a higher risk of colorectal cancer.
