Is there a genetic cause for colorectal cancer?

Oncologists say that the occurrence of colorectal cancer brings great harm to the patient's health, so what causes colorectal cancer? Oncologists say that the causes of colorectal cancer are inseparable from many factors in our daily life. Environmental factors are one of them, and genetic factors are also the main cause of colorectal cancer.

1. Genetic factors: There are reports of "familial colorectal cancer" both at home and abroad. The number of blood relatives of colorectal cancer patients who died of the disease is significantly higher than that of the general population. Some colorectal adenomas, such as multiple familial adenomatosis, are autosomal dominant genetic diseases. The prevalence rate in the family can reach 50%. If not treated, there is a possibility of colorectal cancer after the age of 10. Recently, some scholars have studied the relationship between tumor suppressor genes and colorectal cancer and found that the susceptibility to colorectal cancer and the cause of colorectal cancer are both related to genetic factors.

2. Environmental factors: Studies have shown that among various environmental factors, diet is the most important, and the cause of colorectal cancer is closely related to the high fat consumption in food. In addition, the cause of colorectal cancer may also be related to the lack of trace elements and changes in lifestyle habits.

Is the cause of colorectal cancer related to genetic factors? The above is a detailed introduction. Experts from the Cancer Hospital said that everyone must take preventive measures in daily life, which will be of great help in preventing the occurrence of colorectal cancer.
