Is colorectal cancer hereditary?

Colorectal cancer is a malignant tumor of the digestive system that can affect people's daily lives in severe cases. Studies have shown that if there are two colorectal cancer patients in a family, and they are parents and children or siblings, the incidence of colorectal cancer is relatively high.

Studies have shown that genetic factors play an important role in the development of colorectal cancer in 20%-30% of colorectal cancer patients, and the younger the patient is, the higher the risk of colorectal cancer in first-degree relatives in the family.

Therefore, family members with a family history of colorectal cancer, especially those with a disease age of less than 40 years old, should pay great attention and have regular health checks. The specific precautions are as follows: If there is a colorectal cancer patient in the family, their immediate family members should pay attention to whether there are changes in bowel habits and defecation characteristics, such as constipation, increased bowel movements, bloody stools, abdominal pain, abdominal distension or intestinal obstruction. If the above symptoms occur, go to the hospital for fecal occult blood tests, digital rectal examinations and endoscopic examinations to detect cancer as early as possible.

Therefore, if a direct relative has colorectal cancer, please do not panic. As long as you follow the doctor's instructions for regular follow-up, early prevention, early diagnosis, and early treatment, you will definitely be able to defeat colorectal cancer caused by genetic factors.
