People must pay attention to the causes of rectal cancer

As a common tumor disease in my country, rectal cancer will bring many disasters to the patient's life and health. And people don't know much about the cause of rectal cancer, which directly leads to the spread of this disease, which is very troublesome. Therefore, we must understand the cause of rectal cancer in order to better prevent this disease. Let's take a look at the causes of rectal cancer.

Causes of colorectal cancer include:

1. The cause of rectal cancer is related to genetic factors. In the families of rectal cancer patients, about 1/4 of new patients have a family history of rectal cancer. Relatives have had rectal cancer, and their descendants are more likely to suffer from the disease in their lifetime than the general population. The cell genetic genes change, causing malignant cells with the genetic characteristics of the tumor, forming a familial malignant tumor.

2. Dietary factors are also one of the causes of rectal cancer. High-fat foods such as meat, high-protein foods and low-fiber foods such as starch, potatoes, carrots, etc. have a very important relationship with the occurrence mechanism of rectal cancer. Under the action of colon bacteria, they are converted into cholesterol metabolites and bile acids, which have carcinogenic effects. Low-fiber foods do not absorb water, which reduces the frequency of bowel movements, increases the retention of waste in the intestine, prolongs the residence time of feces in the large intestine, and increases the long-term contact between carcinogens and the large intestine mucosa. This cause of rectal cancer is relatively common.

The above are the causes of rectal cancer. I hope everyone can understand them one by one. As long as people know these causes of rectal cancer, they can do their best to prevent the disease, and then the incidence rate can be greatly reduced. So if you want to get rid of the interference of this disease, please be more careful about the above causes of rectal cancer. I wish all patients can fight the disease to the end.
