"Small symptoms" may indicate "big problems"

Colonoscopy is the most important method for early detection of colorectal cancer, it will be colonoscopy through the anus into the intestinal lumen, you can observe the entire large intestine lumen whether there is a lesion, you can also clamp down on a small piece of diseased tissue for pathological examination, which helps to clearly diagnose and judge the severity of the disease, and then guide treatment
.

With the maturity of endoscopic technology, endoscopic mucosal resection (EMR) and endoscopic submucosal dissection (ESD) have continued to advance, and colorectal polyps can be removed under colonoscopy, early cancer, and
can also be stopped under colonoscopy.

These 22 conditions require colonoscopy

(1) Those with symptoms such as blood in the stool or black stool, or those who have a positive long-term fecal occult blood test;

(2) Stool with mucus, pus and blood;
(3) Those who have a lot of stools, are not formed, or have diarrhea;
(4) Recently had difficulty defecating or irregular stool;
(5) Stool thinning and deformation;
(6) Long-term abdominal pain and bloating;
(7) Unexplained weight loss, weight loss;
(8) Unexplained anemia;
(9) Unexplained abdominal mass, who needs to be clearly diagnosed;
(10) Unexplained elevation of CEA (carcinoembryonic antigen); (11) Long-term chronic constipation, which cannot be cured for a long time;
(12) Chronic colitis, long-term medication, long-term treatment;
(13) Those who suspect colon tumors but have negative barium enema and X-ray examination;
(14) Abdominal CT or other examinations find that the intestinal wall is thickened, and colorectal cancer needs to be excluded;
(15) Lower gastrointestinal bleeding, bleeding lesions can be found, the cause of bleeding can be determined, and if necessary, microscopic hemostasis can be stopped;
(16) Patients who have suffered from schistosomiasis, ulcerative colitis and other diseases;
(17) Colorectal cancer surgery needs to be re-examined regularly after colonoscopy: patients with coloral cancer surgery generally need to re-examine the colonoscopy every 6 months to 1 year, if the colonoscopy fails to check all the colon before surgery because of colon obstruction, then colonoscopy should be performed 3 months after surgery to determine whether there are colonic polyps or colon cancer in other parts;
(18) Those who have been found to have colonic polyps and need to be removed by colonoscopy;

(19) Colorectal polyps need to be reviewed regularly after surgery: polyps of chorionic adenoma, serrated adenoma and high-grade epithelial neoplasia are prone to recurrence and carcinogenesis, it is recommended to recheck the colonoscopy every 3-6 months, and other polyps are generally recommended to re-examine the colonoscopy
every 12 months.
If the re-examination colonoscopy is negative, it is retested after 3 years;
(20) People with a family history of colorectal cancer should undergo colonoscopy screening: If one person in the family has colorectal cancer, his immediate family members (parents, children, siblings) should have a physical examination for colonoscopy even if they do not have any symptoms or discomfort
.
A large number of studies have proved that if a person has colorectal cancer, his immediate family members (parents, children, siblings) are 2-3 times more likely to get colorectal cancer than the normal population;
(21) People with a family history of colorectal polyps also need to undergo colonoscopy screening;
(22) People over the age of 40, especially long-term high-protein and high-fat diets and long-term alcoholics, it is best to do a colonoscopy with a routine physical examination in order to detect some asymptomatic early colorectal cancer
as soon as possible.

Special tips!

1.
Blood in the stool≠ hemorrhoids!
The incidence of hemorrhoids is very high, and blood in the stool is the most common clinical manifestation of hemorrhoids, so many people think that blood in the stool is caused by
hemorrhoids.
This view is extremely wrong, because many other diseases can also cause blood in the stool, such as colon cancer, rectal cancer, fissure, rectal hemangioma, etc
.

2.
Blood in the stool is the most important clinical manifestation
of colorectal cancer.

At the same time, blood in the stool is also a common symptom of dozens of anorectal diseases such as hemorrhoids, fissures, and enteritis, so the real cause
cannot be determined simply based on blood in the stool.
When there is repeated blood in the stool and black stools, you should go to a regular hospital for colonoscopy in time to avoid delaying the diagnosis
.

3.
Hemorrhoids will not cause rectal cancer, but hemorrhoids can be accompanied by rectal cancer
at the same time.

Hemorrhoids are a benign disease that does not evolve into rectal cancer, but patients with hemorrhoids can also get rectal cancer
.
High attention should be paid to it
.

4.
Patients with hemorrhoids should be highly suspicious of rectal cancer
if the blood in the stool is not cured for a long time.

The main symptoms of hemorrhoids and rectal cancer are blood in the stool, and some patients have a history of hemorrhoids, so as long as there is blood in the stool, it is considered to be hemorrhoid bleeding
.
Blood in the stool caused by rectal cancer will also improve after treatment with hemorrhoid embolis, but after a period of time, there will be blood in the stool, repeated attacks, and it will not be cured
for a long time.
At this time, you should go to a regular hospital as soon as possible and perform digital rectal examination and colonoscopy to exclude the possibility of
colorectal cancer.
