This kind of fleshy lump in the stomach may turn into colon cancer! Check it out as soon as possible at this age...

Advice to friends over 40 years old

Include colonoscopy during physical examination

This is really important

There's nothing embarrassing.

Some people don't know unless they check

Intestinal polyps were found upon examination.

This is a big hidden danger

According to data released by the National Cancer Center, approximately 90% of colorectal cancers evolve from adenomatous polyps of the large intestine.

Intestinal polyps are lumps of flesh that grow in the intestines. As long as their pathological nature is not determined, they are collectively referred to as intestinal polyps, generally including colon polyps and rectal polyps.

Generally speaking, intestinal polyps have almost no symptoms. Therefore, for the general population over 40 years old, it is recommended to have a colonoscopy every 5-10 years.

If you have the following high-risk factors, you should have a colonoscopy:

(1) First-degree relatives have a history of colorectal cancer;

(2) The individual has a history of cancer (any history of malignant tumor);

(3) The individual has a history of intestinal polyps;

(4) Those who have two or more of the following conditions at the same time: ① chronic constipation (constipation for more than 2 months each year in the past 2 years); ② chronic diarrhea (diarrhea lasting for more than 3 months in the past 2 years, with each episode lasting more than 1 week); ③ bloody stools with mucus; ④ history of adverse life events (occurring within the past 20 years and causing great psychological trauma or pain to the subject after the event); ⑤ history of chronic appendicitis or appendectomy; ⑥ history of chronic biliary disease or cholecystectomy.

If you really don't want to do a colonoscopy and feel weak when you see a colonoscopy, you can also do these two tests regularly:

Fecal immunochemical test (FIT) (used to detect human hemoglobin in stool samples and is more accurate and sensitive than the traditional fecal occult blood test (FOBT));

Multi-target fecal FIT-DNA detection (simultaneous detection of FIT and tumor-related DNA, etc.).

If the test result is positive, you cannot postpone the procedure and must undergo further screening through colonoscopy.

In addition, there are different screening recommendations for high-risk groups in different situations.

Patients with adenomatous polyposis syndrome or carriers of pathogenic mutations: full colonoscopy once a year;

Lynch syndrome families with pathogenic mutations: Colonoscopy every 2 years starting at age 20-25, then once a year after age 40.

Patients with ulcerative colitis: receive colonoscopy screening within 8 years of symptom onset and receive multiple biopsies of the entire colon;

Screening subjects have 2 first-degree relatives diagnosed with colorectal cancer or advanced adenoma (or 1 first-degree relative diagnosed at the age of <60 years): It is recommended to start colonoscopy at the age of 40 and once every 5 years.

First of all, we need to know that not all intestinal polyps will turn into cancer.

Intestinal polyps can be divided into two types according to their pathological type: neoplastic and non-neoplastic lesions.

Neoplastic polyps: including tubular adenomas, villous adenomas and tubulovillous adenomas, sessile serrated polyps/adenomas, and traditional serrated adenomas;

Non-neoplastic polyps: including inflammatory polyps, hyperplastic polyps, hamartomatous polyps, etc.

As the name suggests, tumor polyps have a certain chance of developing into cancer, especially villous adenomas. If not removed, the patient's probability of cancer after 10 years can be as high as 50%.

Another point to note is that if you suffer from familial multiple adenomatous polyps and do not undergo intervention treatment, the probability of canceration in the long run is extremely high!

Therefore, if there is a family history of intestinal polyps, you must go to the hospital for colonoscopy regularly.

The specific pathogenesis of intestinal polyps has not yet been determined. However, a large number of related studies believe that the occurrence of intestinal polyps may be related to these factors:

Age factor: The incidence of intestinal polyps increases with age;

Dietary factors: The incidence rate is higher in people who have a long-term low-fiber diet;

Chronic intestinal inflammation: such as chronic ulcerative colitis, amoebic dysentery, intestinal schistosomiasis, Crohn's disease and intestinal tuberculosis. The intestine is in an inflammatory state for a long time, and the probability of forming inflammatory polyps will be greatly increased;

Genetic factors: About 10% to 27% of colorectal cancer patients have a family history of cancer.

In view of the above-mentioned factors, the preventive measures that everyone can take are very obvious. To sum up, we must ensure a reasonable diet and conduct preventive screening in advance.

It takes a long time for intestinal polyps to develop into cancer. As long as they are discovered and treated early, the occurrence of intestinal cancer can be avoided with a high probability.
