Wang Guiqi, a member of the National Committee of the Chinese People's Political Consultative Conference, said that tumors do not grow in a day. The only symptoms of malignant tumors in the early stage are no symptoms. Once symptoms appear, they are basically in the middle and late stages.

Have targeted screening when you think you are healthy.

Staying away from tobacco and alcohol, proper activities, and reasonable diet can prevent 1/3 of malignant tumors.

In addition, high-risk groups, whether you have symptoms or not, should take the initiative to do screening when you are 50 years old, do early diagnosis, and do gastrointestinal endoscopy to avoid late occurrence.
