Bowel cancer is difficult to detect in the early stages without screening Dr. Sun Zheng, Chief Physician of Gastrointestinal Surgery Department, introduces that most bowel cancer patients have been found to be in the middle or late stages of bowel cancer, and the treatment effect is poor. Most colorectal cancers are not easy to detect in the early stage, and it is basically hard to find without screening. Dr. Li Yongqiang of Gastroenterology said that most of the early colorectal cancers do not have symptoms, and many people think that it is just an ordinary stomach pain, and do not pay attention to the condition. Early colorectal cancer can be diagnosed through screening, and colonoscopy is the best way to check it at present. Colonoscopy is not so painful Deputy Chief Physician of Gastroenterology Feng Zhiqiang introduced that the current means of colorectal cancer screening include fecal occult blood test, rectal fingerprinting, colonoscopy, X-ray barium enema and so on. Be sure to emphasize early screening. Speaking of colonoscopy, Dr. Wang Hong, chief physician of Gastroenterology Department, introduced that colonoscopy includes ordinary colonoscopy, sedation colonoscopy, painless colonoscopy, etc. Not all colonoscopies are painful, among which painless colonoscopies can be done in the state of “sleeping”. Early radical surgery for bowel cancer is effective Some statistics point out that early detection of colorectal cancer can save more than half of the treatment cost, but according to the data released by WHO in 2008, the 5-year survival rate of colorectal cancer in China is only 32%, which is related to the late discovery of the disease by patients. Experts say that early stage bowel cancer, or stage I bowel cancer, can be treated with surgery. The five-year survival rate after radical surgery can reach more than 90 percent, while the survival rate for advanced colorectal cancer drops to 5.7 percent.
