What causes rectal tumors

Diseases all have their causes. In order to detect diseases early and treat them early, we need to understand them in detail. Let's take a look at the factors that lead to rectal tumors.

Experts introduce the factors that lead to rectal tumors:

(1) Age and gender: The prognosis of colorectal cancer in young people has long attracted the attention of scholars at home and abroad. According to domestic statistics, the prognosis of colorectal cancer in young people under the age of 30 is poor. Among 3,147 cases of colorectal cancer, the 5-year survival rate after surgery for young people was 40.1%, while that for elderly patients was 51.4%.

(2) Clinical symptoms and complications It is generally believed that the 5-year survival rates of patients with and without clinical symptoms are different. According to reports, the 5-year survival rate of the symptomatic group is 49%, while the 5-year survival rate of the asymptomatic group, who were prompted to seek medical treatment by occult blood in their stool during the census, is 71%. When complications occur during the course of the disease, the prognosis is poor. The prognosis is also different depending on the complications.

① Bleeding: Patients with bleeding as the main symptom have a better prognosis. This is related to early diagnosis and treatment of patients. According to reports, the 5-year survival rate of patients who seek treatment mainly for bleeding is 54%.

② Obstruction: The prognosis of patients with intestinal obstruction is poor, and the 5-year survival rate after resection is 30% to 40%. The main reason is that only 50% of patients with obstruction can undergo radical surgery, while more than 80% of patients without intestinal obstruction can undergo radical surgery.

(3) Location of primary tumor: The location of colorectal tumor is related to prognosis. Right colon tumors have the best prognosis. It is reported that the 5-year survival rate of patients with right colon tumors is 72%, descending colon tumors is 68%, sigmoid colon tumors is 44%, and rectal tumors is 47.4%.

The above is the answer to the question "What are the factors that cause rectal tumors?" People who are related to the above factors that cause rectal tumors should take preventive measures against rectal tumors.
