Despite the fact that we do not know exactly the reasonsthe development of most tumors of the colon and rectum, but all the same it is possible to prevent many cases of this cancer. In conducting the screening it is possible to detect and remove colon polyps, which can become a future cancer. Reduction in mortality can be achieved through the diagnosis of tumors in the early stages of the disease when treatment is highly effective.
Prevention and early detection of tumorspossible, since most cases of colon cancers develop from adenomatous polyps. Polyps are precancerous conditions of the colon and rectum. Their removal may reduce the risk of cancer.
Diet and physical activity
To reduce the risk of developing colorectal cancer, possibly due to the influence of factors such as diet and physical activity.
It is important to eat plenty of fruits, vegetables,products from corn meal and limit their intake of high-fat foods. Recommend at least a 30-minute physical activity five or more times per week.
If you are engaged in moderate or vigorousphysical activity for 45 minutes five or more times a week, you may thus even further reduce breast and colon cancer risk. In the case of overweight, try to lose weight to normal weight and maintain it.
Vitamins and Calcium
It is believed that the daily use of a multivitamin containing folic acid or folate, can reduce the risk of colorectal cancer.
It is known that an increased calcium intake forthrough supplements or foods low in fat, also reduces the risk of cancer of this localization. Vitamin D, we obtain under the influence of the sun, as well as vitamins or milk, can reduce the risk of colorectal cancer.
Indeed, in areas with sufficientsunny days colorectal cancer incidence below. On the other hand, we do not recommend using an intense sun exposure as colorectal cancer prevention, since it can cause skin cancer.
Non-hormonal anti-inflammatory drugs
Many studies have shown that people,regular use of aspirin and other nonsteroidal anti-inflammatory drugs have a 40-45% lower risk of colorectal cancer and adenomatous polyps.
However, this information is not final, therefore, these drugs can not be recommended to reduce the risk of colorectal cancer.
Hormone replacement therapy in womenpostmenopausal women may slightly reduce the risk of colorectal cancer. Such therapy also reduces the risk of osteoporosis, but may increase the risk of heart disease, blood clots, and breast and uterine cancer.
Therefore, the decision to use hormone replacement therapy should be decided together with the doctor, taking into account the benefits and risks of such treatment.
There are other risk factors thatIt can not be influenced, such as family history of colorectal cancer. However, in this case, it is possible to prevent the disease - to take part in screening at a young age and to do special studies are more likely than those who do not have this risk factor.
Genetic studies may help identify the family with inherited high risk of developing colorectal cancer.
People with familial adenomatous polyposis shouldto do a colonoscopy, beginning in adolescence. There recommendations removal of the colon, aged 20 to 30 years with a view to preventing the development of cancer in it.
The risk in people with a hereditary nonpolyposis cancercolon lower than those with familial adenomatous polyposis. People with a hereditary nonpolyposis colon cancer with colonoscopy is recommended 20 years in order to identify and remove polyps and to identify cancer in its earliest stages. However, prophylactic removal of the colon in people with a hereditary nonpolyposis colon cancer is usually not recommended.
Given the fact that some types of colorectal cancer can not be prevented, it is necessary to strive for the early diagnosis to improve the prognosis of the disease.
