Three common non-dietary causes of rectal cancer

The causes of most digestive tract cancers, including colorectal cancer, are generally caused by diet, but many patients will find that they will get colorectal cancer even if they pay attention to their diet. The causes of these colorectal cancers are not simple dietary issues.

1. Genes and hereditary factors are also one of the causes of rectal cancer. The chances of rectal cancer and adenoma in the immediate family members of rectal cancer patients are several times higher than that of normal people.

2. Environmental factors. The incidence of colorectal cancer in economically backward countries is generally lower than that in developed countries, but the incidence of colorectal cancer in the upper class is higher than that in the lower class. This is because the upper class's eating habits tend to be high in fat and low in fiber, which is one of the causes of colorectal cancer.

3. Other cancers may also be the cause of colorectal cancer. People who have suffered from thyroid cancer, breast cancer, ovarian cancer or endometrial cancer will also have a higher chance of developing colorectal cancer, which is related to endocrine hormones.

The above analysis of the causes of rectal cancer is believed to be helpful for you to understand rectal cancer. It must be said that even if diet is not the main cause of rectal cancer, it is also a major factor in inducing rectal cancer and is something that needs special attention.
