The incidence of colorectal cancer is increasing year by year, and it is important to pay attention to protection
In the 1970s, nine out of every 90,000 people suffered from colorectal cancer, and after that, the incidence rate of colorectal cancer has been increasing at a rate of 10 percent year by year, and the incidence rate is even higher in developed cities, and the incidence rate of colorectal cancer has been soaring all the way up, which has drawn people’s attention and protection.
Colorectal cancer incidence areas
As we all know, human intestine is divided into two parts, which are small intestine and large intestine, and the large intestine includes colon and rectum, if there are tumors in these two parts of colon and rectum, then it can be called colon cancer.
The left half of the intestine (rectum, sigmoid colon and descending colon) accounts for 80% of cancers, while the right half of the intestine (ascending colon) accounts for 25% of cancers. However, rectal cancer has the highest incidence rate, accounting for roughly 60% of colorectal cancers.
7 Causes of Colorectal Cancer
So what exactly triggers colorectal cancer? What are the high-risk factors that trigger colorectal cancer?
1.If the patient is constipated for a long time, the feces in the body will stay in the colon for a longer time, so these substances will have a bad effect on the mucous membrane of the intestinal wall.
2, long-term loose stools. There are various reasons for loose stools, one of which is colorectal polyps, if polyps are not found for a long time, they can collapse into cancer. The longer the loose stool, the greater the need for colonoscopy.
3.High protein and high fat diet, the metabolites of these foods in the body can easily induce cell malignancy, which can lead to colorectal cancer.
If the inflammatory disease is not treated for a long time or is not treated properly, the disease may recur, and then the disease may cause colon cancer if it lasts more than seven years.
5. Genetic factors are also the cause of colorectal cancer, so people of different ages with family history of colorectal cancer should be alert to the emergence of colorectal cancer symptoms at all times.
6.75% of colorectal cancer comes from colorectal polyps, so patients with long polyps should go to hospital for colonoscopy regularly.
7.Among the patients with bleeding hemorrhoids, there are already some people who already have polyps or tumors in the large intestine above the anus. If only some bleeding symptoms are noticed in the diagnosis, some important or dangerous diseases in the large intestine are likely to be unchecked, and it is recommended that patients with hemorrhoids must go to the hospital’s gastroenterology department for colonoscopy afterwards.
