Is colon cancer screening done by rectoscopy or colonoscopy

Many people have a poor appetite in summer, and many people think it is because of the hot weather. In fact, this is a precursor to rectal cancer, which is a reminder for you to pay attention. Many people did not go to the hospital for examination in time in the early stage, and then delayed the disease. Even if they had surgery, the effect was not so good. Therefore, everyone should do colonoscopy regularly to detect some diseases early.

At present, the incidence and mortality of colorectal cancer in my country are both ranked second among cancers, and more than 60% of colorectal cancers are rectal cancers. The editor learned from experts that 80% of rectal cancers are misdiagnosed as hemorrhoids, dysentery, etc. Some patients were misdiagnosed and treated incorrectly for more than half a year before being discovered, delaying the disease. Experts remind that people over 40 years old are best to have regular colonoscopy examinations.

Low intake of crude fiber increases the incidence of

According to experts on colorectal cancer, the incidence and mortality of colorectal cancer in China have been on the rise in recent years. In the 1970s, the mortality rate was 3.54 per 100,000 people, and in 2005 it was 4.54. The incidence rate in men is higher than that in women. According to the latest statistics, the number of new cases of colorectal cancer in my country is about 130,000 to 160,000 per year, and the number of deaths is about 60,000 to 90,000. It mostly occurs in large and medium-sized cities, and ranks second only to gastric cancer among digestive tract tumors.

Unlike many diseases that tend to occur at younger ages, the incidence of colorectal cancer is showing an "aging" trend: the median age used to be 45, but now it is 55. The peak age of onset has changed from the 40s and 50s to the 60s and 70s. In contrast, the proportion of adolescents suffering from colorectal cancer is constantly decreasing, from about 20% in the past to the current 6.6%.

It is understood that the reason for the increase in the incidence rate is mainly related to the increase in high-fat and high-protein intake of modern people and the lack of exercise and crude fiber intake. The "aging" trend is mainly due to the increase in the overall life expectancy of the population, the improvement of cognition, and the enhancement of health awareness.

Since there are no symptoms in the early stages of rectal cancer, it is difficult to detect. Only by looking at the intestines can we tell whether cancer has occurred. For the sake of your own health, it is recommended that you go to the hospital for regular physical examinations. In this way, even if rectal cancer is detected, it is in the early stages and is easy to treat. With current medical technology, it can still be cured. Once you find out that you have rectal cancer, you must receive treatment in a regular hospital.
