If there is cancer in the body, your fingers will tell you. What characteristics on your fingers indicate that you should have a physical examination?

Nowadays, cancer can be said to be a very common disease in our lives. When it comes to cancer, we are all frightened by it, because cancer implies that we are about to die. There is cancer in the body. Finger prophets generally have lung diseases. The patient's fingers will appear "club-like", the ends of the fingers/toes will become larger, and the curvature of the nail surface of the fingertips will gradually increase. If early-stage lung cancer can be detected and treated promptly, the 5-year survival rate can reach 99%. Time is of the essence for patients. In other words, it is a critical period to save one's life.

This change is not sudden, it only occurs over a long period of time. Usually it occurs under the long-term erosion of chronic diseases, but clubbing is not only related to lung cancer. It also includes: insufficient oxygen in the blood, certain lung diseases, intestinal diseases, cardiovascular diseases, and many other factors. There is insufficient evidence to judge that lung cancer is obvious just by clubbing the fingers, and it is too arbitrary.

Because early-stage lung cancer itself has no symptoms, or there may be symptoms similar to colds, such as dry cough. It is not scientific to judge lung cancer simply by symptoms, so we need to use more advanced detection methods. Low-dose CT screening is the best examination method. It replaces the previous chest X-ray, reduces missed or misdiagnosed, and improves the diagnosis rate. The United States has conducted an experiment involving 500,000 people with low-dose chest CT screening for lung cancer. Preliminary results show that the risk of lung cancer in patients diagnosed with lung cancer using low-dose CT screening is 16% lower than that in patients with chest plain radiographs.

People at high risk of lung cancer are mainly old smokers who never leave tobacco and alcohol. According to the National Comprehensive Cancer Network lung cancer screening guidelines, people at high risk of lung cancer are defined by these two characteristics: mainly smoking a pack a day. Count * years of smoking, for example: if you smoke 3 packs of cigarettes a day for 10 years, then you have 30 pack-years. The simplest and most effective way to prevent lung cancer is to quit smoking, and the earlier the better.
