γγThe exact cause of colorectal cancer is not clear, but according to clinical research, it is likely to be related to people’s dietary habits, family genetic factors, chronic diseases, bad living habits and mental stress.γγ1.People who like to use high protein food. Inherently, protein is necessary for the human body, but if consumed in excess for a long time, it is easy to cause indigestible and lead to the accumulation of toxins inside the body, thus generating cancer risk; 2. People who are over 40 years old. Although cancer may occur in any age group, bed cases show that about 90% of patients are older than 40 years old. Understanding this, we should have regular checkups above the age of forty; 3. People with long-term constipation and blood in stool. Some data show that about 80% of people do not know that blood in stool is a signal of bowel cancer. Long-term constipation may lead to dry stool and accumulation of toxins in the intestine, and so on and so forth, which may induce blood in stool in serious cases. Experts say that blood in stool may be a pre-cancerous warning; 4. People with related chronic diseases. Although certain chronic intestinal diseases do not necessarily develop into cancer, clinical evidence shows that patients with chronic ulcerative colitis for more than ten years have several times higher risk of colon cancer than the general population; and patients with colorectal polyps have 22 times more such risk than the general population. In addition, intestinal diseases such as colorectal adenoma and familial colonic adenomatosis are also included. In addition, non-intestinal diseases may also contribute to the risk of colorectal cancer, such as schistosomiasis, long-term people with chronic appendicitis, cholecystitis or those who have had their appendix and gallbladder removed; 5. People with a family history of genetic predisposition. Among the known cases of colorectal cancer, about nearly a quarter of colorectal cancer patients may be mainly due to genetic factors. For example, people with family history of adenomatous polyposis and hereditary non-polyposis colorectal cancer have 2-4 times higher risk of colorectal cancer than the general population; 6. People with long-term mental depression. Long-term mental depression will lead to the conversion of psychological diseases into physical diseases, while stress and depression are not conducive to physical recovery, which will form a physical burden over time; 7, people who stay up late for a long time. Staying up late for a long time will not only lead to fatigue and weakness, but also may induce a variety of diseases, in terms of the intestinal tract, because the metabolism is slowed down, the body’s function decreases and leads to the accumulation of toxins in the body and thus causes cancer.
