The occurrence and development of colorectal cancer is a multi-stage and long proce.

The occurrence and development of colorectal cancer is a long and multi-stage proce.

A study abroad has compared two groups of people who have had intestinal polyps removed and those who have not had intestinal polyps removed, and found that people who have had intestinal polyps removed have a 4-fold lower risk of colorectal canc.

About 30% of middle-aged and elderly people will have intestinal poly.

Generally speaking, larger diameter polyps are more likely to be cancerous, depending on the doctor's examination resul.

Early detection and early treatment is the key to reducing mortality

If detected early, early-stage colorectal cancer is very effective after treatment, with a 5-year survival rate of 9

Polyps should be removed in time after the age of 40

People over the age of 40 should have regular colonoscopy and anoscopy examinations, which can detect polyps early, remove them early, and avoid canc.

People over the age of 40 should have regular colonoscopy and anoscopy examinations, which can detect polyps early, remove them early, and avoid canc.

If the colonoscopy is normal, it can be re-examined every 3 to 5 years;

Colonoscopy with polyps should be reviewed every 3 to 6 months;

Colonoscopy with polyps should be reviewed every 3 to 6 months;

Those with multiple intestinal polyps can be removed simultaneously during colonoscopy;

Colorectal adenomas or precancerous lesions can be diagnosed early and treated early by colonoscopy in high-risk groups through screening , census, and colonoscopy, which is a very important part of the tertiary prevention of colorectal cance.

Secondary prevention focuses on screening, census, early diagnosis and early treatment of precancerous lesions;

The rational use of tertiary preventive measures can reduce the morbidity and mortality of colorectal cancer and improve the 5-year survival ra.

Genetic factors are important

Studies have found that genetic factors play an important role in colorectal canc.

Among family members of colorectal cancer patients, the incidence of colorectal cancer is 3-4 times higher than that of the general population , and family history of colorectal cancer is a high-risk factor for colorectal canc.

About one-third of colorectal cancers are genetically related, of which familial adenomatous polyposis (FAP) and hereditary nonpolyposis colorectal cancer (HNPCC) are the most common hereditary colorectal cance.

Transanorectal adenoma resection can be considered for small low rectal adenomas, open surgery can be considered for colorectal adenomas that are more than 8 cm away from the anus, large, broad-based, and suspected cancero.

Laparoscopic surgery can also be considered for colorectal adenomas that can only be removed by open surge.

Colorectal cancer is a solid tumor and the most effective treatment is surgical resecti.

And effective chemoradiotherapy drugs can well control the development of colorectal cancer after surge.

The efficacy of colorectal cancer depends on the following factors:

And effective chemoradiotherapy drugs can well control the development of colorectal cancer after surge.

The efficacy of colorectal cancer depends on the following factors:

Degree of malignancy: The degree of differentiation of colorectal cancer is well differentiated, moderately differentiated, and poorly differentiat.

Poorly differentiated cancers are very different from normal tissues and have a high degree of malignancy; well-differentiated cancers are more like the original structure of normal tissu.

Discovery sooner or later: The earlier the discovery, the better the effe.

Colon cancer is detected at an early stage, and the cure rate after surgical resection is as high as 9
If it is found late, the lymph nodes have metastasized, and the tumor is relatively large, it needs to be combined with radiotherapy and chemotherapy, and the five-year survival rate can reach 50% to 6
If it is accompanied by extensive liver or lung, surgery alone is more difficult, and even with strong chemotherapy or targeted therapy, the five-year survival rate is only about 1
