In the impression of many people, lung cancer, stomach cancer, liver cancer and other cancers seem to have a feeling of being on the verge of a great enemy when facing them.
However, colorectal cancer, a cancer with a very low presence, is often automatically ignored.
"Colorectal cancer, it doesn't seem to be very common?"
"I haven't heard of it, it shouldn't be common, right?" ........
But in fact, colorectal cancer is not uncommon, according to the data: in the past 30 years, the number of colorectal cancer patients in China has increased by 700%, becoming the country with the largest number of confirmed bowel cancer in the world.
Among the top five cancers in 2019, colorectal cancer also became the most prevalent digestive cancer in the mainland, especially after the age of 40-50, the incidence increased significantly.
But unlike other cancers, this cancer has been detected in the human body for more than 10 years. Among all the tumors of the digestive system, colorectal cancer is also the most "preventable" and the best "treatment".
After early colorectal cancer treatment, the 5-year survival rate can be as high as 90%, while in the advanced stage, it is less than 12%.
Is abnormal bowel movement a precursor to bowel cancer?
Generally speaking, normal people do not defecate more than 2 times a day, and the color of the stool is biased towards yellow-brown, cylindrical, and the texture is relatively soft.
If you notice that your stool is black and foul-smelling, be vigilant.
It may be a problem with the intestine, such as gastroenteritis, intestinal dysbacteriosis, and worst of all, bowel cancer.
There are 4 kinds of abnormalities in bowel movements, it is best to go to the hospital to check it!
1. Habitual diarrhea
As the saying goes, illness comes from the mouth. Nowadays, some young people especially like to eat roadside stalls, some fried foods are directly under the pot without washing, can not ensure the cleanliness and hygiene of the diet, easy to infect enteritis after eating, and eventually appear diarrhea symptoms.
If you find that you have diarrhea, you must go to the hospital in time for treatment. If you do not do a good job of nursing work for a long time, you are likely to develop bowel cancer.
2. Blood in the stool
Hemorrhoids and rectal cancer are more similar in incidence, it is easily confused with hemorrhoids, the most common symptoms are blood in the stool.
Most people have blood in their stools caused by hemorrhoids, but some people are the early manifestations of rectal cancer. Bleeding from rectal cancer is "active" old bleeding, and once the stool rubs against the cancer tissue, it is easy to cause bleeding.
If you do not have hemorrhoids, you should go to the hospital as soon as possible to check whether it is caused by rectal cancer, and control the development of the disease in time.
3. Changes in stool traits
If you find that your stool characteristics have changed and there is a tendency to thin, you should pay attention to it and check in time to see if you have rectal cancer.
If there is a cancerous mass in the patient's rectum, it is easy to block the intestinal lumen, resulting in thinning of the excreted feces, which is often referred to as a change in stool traits.
4. Difficulty defecation
Some patients have symptoms of difficulty defecation, accompanied by distention, and want to go to the toilet and can not pull out should be taken seriously. It can be a sign of rectal cancer, and it is best to go to the hospital early for examination.
Colonoscopy is a key means of effectively screening cancer
For bowel cancer, there are also many related examination items in the clinic, which can be screened early.
One of the most common is colonoscopy, which helps doctors directly observe the inside of the colorectum, minimize misdiagnosis or missed diagnosis, and also find polyps.
Clinically, half of the rectal cancer is transformed by adenomatous polyps, and it is necessary to actively treat the primary disease to prevent the rectum from being stimulated for a long time and malignant to form rectal cancer.
If you find that you have the above abnormal manifestations of defecation, you must go to the hospital in time for colonoscopy-related examinations. Once an adenoma is found in the large intestine, surgical removal is done and pathological examination is done to understand whether the tumor is benign or malignant.
If there is a genetic history of bowel cancer in the family, it is even more vigilant.
Cooperate with the doctor to actively fight cancer as soon as possible, and do regular colonoscopy to nip the disease in the bud.
Therefore, for parents who have entered the high incidence of colorectal cancer, it is more necessary to include colonoscopy in the physical examination program.
So, don't you hurry up and arrange it for your parents?
