In recent years, the number of colorectal cancer patients in China has increased significantly. According to the latest medical survey in 2015, colorectal cancer has become the fourth leading cause of death from malignant tumors. Colorectal cancer belongs to the category of digestive system tumors, which includes rectal cancer and colon cancer, among which rectal cancer has the highest incidence rate, accounting for about 65% of the number of colorectal cancer patients. In addition, the incidence of rectal cancer is getting younger and younger, and the number of men is 1-2 times more than that of women. What are the clinical manifestations of rectal cancer and colon cancer respectively? Rectal cancer is mainly manifested by an increase in the number of stools, a decrease in the volume of stool, and in severe cases, blood in the stool. When the cancer spreads to the rectum and invades the sacral plexus nerve, severe pain will appear in the pelvic area, and it will easily cause hemorrhoids. In addition, if the cancer has spread to the prostate or bladder, symptoms such as frequent urination, urgent urination, painful urination, poor urination and hematuria will occur, and a fistula will be formed, which will endanger the bladder and reproductive organs. Colon Cancer Colon cancer is divided into two different cases: left colon cancer and right colon cancer. Patients with colon cancer usually have lumps in their abdomen, which can cause abdominal pain and bloating, and they can easily become constipated. In addition, in the advanced stage, intestinal perforation and pus may occur. What is the survival rate of colorectal cancer patients in general? 1.Survival rate after surgery in early stage: If patients have discovered the disease in early stage and undergone surgery and other treatments, they can basically be cured (but after cured, they must go to the hospital frequently for regular checkups, because colorectal cancer is easy to recur). 2.Survival rate after surgery: Generally, when colorectal cancer patients are diagnosed, most of them are already in the middle and late stage, and the survival rate after treatment at this stage is only 5%-20%. How to improve the survival rate of colorectal cancer patients? 1.Active treatment Active cooperation with treatment is the best way to improve survival rate, and surgery is the most rapid and highest cure rate treatment method. 2.Exercise According to the research of Dana-Farber Cancer Institute, regular and moderate exercise can greatly improve the survival rate of colorectal cancer patients (the amount of exercise varies from person to person, you can do appropriate exercise according to your own condition). 3.Diet Eat more fruits and vegetables and other plant foods rich in high fiber, such as asparagus, golden needles, yam, etc. It is better not to eat fried and spicy foods.
