These five types of people are prone to colorectal cancer, and you must understand three effective tests

The most common symptoms of colorectal cancer

The stool suddenly becomes very thin;

Blood in stool;

Sudden constipation, diarrhea, or feeling of being unable to pull clean;

Sudden abdominal flatulence, fullness, or colic;

No weight loss, but serious weight loss; Tired and powerless.

Who are the high-risk groups?

First, older people. More than 90% of colorectal cancer is caused by people over 50 years old.

Second, people with a history of intestinal polyps or colorectal cancer.

Third, people with inflammatory bowel disease. For example, people who have had ulcerative colitis or Crohn's disease before.

Fourth, there are two kinds of familial hereditary diseases: one is familial adenomatous polyposis, the other is hereditary nonpolyposis colorectal cancer.

The fifth is the person whose family has suffered from colorectal cancer or colon polyp.

In addition, some unhealthy lifestyles, such as smoking, drinking and lack of exercise, will increase the risk of colorectal cancer. However, the proportion of red meat (pork, beef, mutton, etc.) in food is too high, the consumption of processed meat (ham sausage, lunch meat, etc.) is too much, or the food fiber is too little, which is also closely related to the occurrence of colorectal cancer.

Three effective checks

First, check stool, that is, highly sensitive stool occult blood test. Colorectal cancer is on the surface of the intestine and sometimes produces a small amount of blood, which will be discharged through stool.

Second, sigmoidoscopy. This is a relatively short fiberscope, which can detect tumors early.

Third, colonoscopy. This mirror is longer and can examine the whole large intestine.
