What causes rectal cancer?

Rectal cancer may be related to genetic factors, unhealthy living habits, chronic intestinal diseases and other factors.

The specific analysis is as follows:

1. Genetic factors: Related studies have pointed out that rectal cancer has a tendency to be inherited and clustered in families. Some direct relatives have this disease, and the incidence rate is relatively high, which may be related to genetic susceptibility genes. Rectal adenomatous polyposis is an autosomal dominant genetic disease that is more likely to develop into rectal cancer.

2. Unhealthy lifestyle habits: Maintaining a high-fat, low-fiber diet for a long time, consuming a large amount of high-fat foods such as fatty meat, processed meat, red meat, fried foods, sitting for long periods of time, smoking, drinking alcohol, etc., can increase the incidence of the disease.

3. Chronic intestinal diseases: In addition to intestinal adenomatous polyposis, some chronic intestinal diseases can also increase the incidence of rectal cancer, such as chronic nonspecific ulcerative colitis, Crohn's disease, intestinal schistosomiasis, etc.

In addition to the three common causes mentioned above, it may also be related to environmental factors, aging, etc. It is recommended that people with adenomatous polyposis and a family history of colorectal cancer, people over 45 years old, and people with a history of chronic intestinal diseases should see a doctor regularly for targeted cancer prevention screening. If you experience persistent or paroxysmal changes in bowel habits, diarrhea or constipation, bloody stools, and other symptoms, you should also see a doctor as soon as possible to identify the cause and treat the symptoms.
