According to the associated press on August 29th, Chadwick Bosman, the actor of panther, has died of colon cancer, causing concern. Huang Meijin, director of the first division of colorectal and anorectal surgery of the Sixth Affiliated Hospital of Sun Yat sen University, said that colorectal cancer, also known as colorectal cancer, is a common gastrointestinal malignancy. Its occurrence is related to diet, carcinogens, intestinal inflammatory diseases and genetic factors.
Panther actor Chadwick boseman died of colon cancer at the age of 43. Bosman was diagnosed with colon cancer four years ago.
Colorectal cancer is one of the nine most common malignant tumors in China, and the death rate of colorectal cancer is high every year. Early screening of colorectal cancer can achieve the purpose of early diagnosis, early treatment and improving the curative effect. The most common early screening includes stool screening and colonoscopy.
Studies have shown that the vast majority of patients with colorectal cancer are the first to appear intestinal polyps, due to the lack of timely diagnosis and treatment and gradually develop to colon cancer. Intestinal polyp is an augmentation of intestinal mucosa surface, which generally refers to the tissue growing on the intestinal wall and protruding to the intestinal cavity. In most cases, the small volume, inflammatory or proliferative polyps have low risk of canceration.
Huang Meijin said that in general, the larger the polyp volume, the more likely it is to be malignant or precancerous lesions. Most intestinal polyps do not cause symptoms, so it is difficult for patients to detect by themselves. The most common symptom is bloody stool. Large polyps may also cause abdominal pain or intestinal obstruction or even intussusception (intussusception refers to the intussusception of one segment of the intestine into another, like a folded kaleidoscope).
Intestinal polyps usually need to rely on electronic colonoscopy to be found. When doing colonoscopy, doctors will collect some samples of intestinal polyps to see how much cancer risk they have through pathological examination.
Once there is abnormal stool, it will ring the alarm of bowel cancer, including the change of stool characteristics, mucus stool, purulent stool or stool becoming thin; stool habits change, such as stool on time every morning, suddenly change the time; stool frequency changes, once a day into a few times a day or constipation, diarrhea alternate, then endless feeling.
For colorectal cancer, according to the location of the tumor length, the performance is often different.
The food residue first enters the right colon through the terminal segment of the small intestine, which is still mushy and does not form. After reaching the left colon and rectum, the water is absorbed, and the stool is gradually formed. In addition, most of the tumors in the right colon were mass growth, and the intestinal cavity was not easy to narrow. Most of the left colon is ulcerative growth, easy to form intestinal stenosis. Therefore, the main manifestations of right colon cancer are anemia, emaciation and abdominal mass, while the left colon cancer is mainly characterized by intestinal obstruction and abdominal pain, and rectal cancer is characterized by increased stool frequency and bloody stool.
From normal intestinal mucosa to adenomatous polyp (especially villous adenoma, the probability of canceration reaches 25% - 85%) and then to tumor, it usually takes 5-10 years. During this period, in the absence of symptoms, the normal population began to do colonoscopy at the age of 40, which can play an early role in the detection of colorectal cancer, while the high-risk population needs to be advanced to 35 years old. If polyps are found in the general survey, regular reexamination should be conducted after resection.
Huang Meijin said that in general, whenever any of the above mentioned changes in stool, or unexplained weight loss, anemia, or abdominal lumps are found, they should first go to the Department of Gastroenterology or gastrointestinal surgery of a regular hospital to screen for cancer.
Huang Meijin said that the daily diet advocated eating more high fiber, low-fat food, such as vegetables and fruits, not fried food and animal oil; maintain good living habits, do not smoke, drink less, stay up late, develop the habit of defecation every day to prevent constipation; properly supplement calcium to reduce the occurrence of intestinal polyps.
