Who are the high-risk groups for colorectal cancer

People at high risk of colorectal cancer are much more likely to develop the disease than normal people. Understanding this group of people will not only help explore the causes of colorectal cancer, but also help reduce the incidence and mortality of colorectal cancer.

People at high risk of colorectal cancer include:

1. The Yangtze River Delta, the Pearl River Delta, and Hong Kong, Macao, and Taiwan are high-incidence areas for colorectal cancer, with Jiangsu, Zhejiang, and Shanghai being the highest-incidence areas. The incidence of colorectal cancer in urban Shanghai is 48/100,000 for men and 45/100,000 for women, which is close to the incidence in Western developed countries.

2. Those who have had colorectal polyps or whose parents or siblings are found to have familial multiple intestinal polyposis with more than 100 polyps.

3. Those whose family members have suffered from adenocarcinoma, such as lung cancer, colon cancer, stomach cancer, thyroid cancer or breast cancer.

4. People who have undergone colonoscopic electrocautery for colorectal polyps.

5. Patients with chronic ulcerative colitis who have not been cured for a long time, people with multiple colon polyps, etc.

6. The incidence of rectal cancer increases significantly in people who have received pelvic radiotherapy, especially those who have received radiotherapy for female reproductive organ tumors.

7. People who have undergone cholecystectomy and patients with schistosomiasis.

8. Those who have high work pressure, irregular lifestyle, long-term constipation or changes in bowel habits.

Special note: The American Cancer Research Association believes that the following two categories of normal people should also pay attention

1. From the perspective of age, statistics show that 91% of colorectal cancer deaths occur in people over 50 years old, so people over 50 years old should pay more attention and go to the hospital for regular check-ups.

2. From the perspective of gender, statistics show that the probability of men suffering from colorectal cancer is 35% higher than that of women, so men should pay more attention to regular screening.
