We need to have two clear understandings about cancer: 1. Cancer can not be avoided by anyone, and everyone needs to take precautionary measures and correct judgment. 2. There needs to be a correct new view on cancer – cancer is a chronic disease. But people may have 5 wrong perceptions about cancer: 1. If countermeasures are not taken in time, the tumor will soon expand and die. Cancer is a chronic disease, and if the mind is relaxed and countermeasures are correct, most people will not die immediately, and clinically there are few patients who die quickly after getting cancer. Among the patients who die quickly, many of them die not from cancer but from the fear of death. 2.If not actively treated before it is too late, cancer will metastasize immediately. Usually, the development of most cancers is a chronic process; of course, some patients will progress very fast in a progressive state at a later stage. Generally speaking, it develops slowly in many cases, and definitely will not metastasize tomorrow without surgery today. This is a misconception because clinically, many cancer patients eventually die due to other factors, and some even die naturally in their old age. Therefore, the death process of most patients does not seem to be that painful. 4. Cancer cells divide quickly and the disease will expand dramatically This is a wrong conclusion that people naturally associate with. Usually, the division of cancer is not very fast, and it will only grow like crazy in the late progressive stage, especially after you take the devastating countermeasures such as constant chemotherapy and radiotherapy, the physique will get worse and worse, plus his own high degree of fear, many factors combined together will most likely lead to a more painful death process for cancer patients. In fact, cancer fight is a fight between normal cells and abnormal cells of human, if your body is weak, cancer cells will grow faster. 5.Surgery must be thorough in order to eliminate the root of the disease This view was not only the people’s conviction, but also the professionals’ opinion. Because cancer is feared and surgery is one of the very best ways to treat cancer, it leads to an extreme measure: “I want to do everything I can to kill cancer.” Breast cancer, for example, used to be treated with extended radical surgery, with bigger and bigger incisions and more and more trauma. The trauma itself exacerbates the “internal chaos” in the body, and severe trauma can contribute to the spread of cancer cells. Therefore, since the mid- to late-1990s, there has been an increasing emphasis on using modified surgery to preserve the breast as much as possible and using radical surgery as little as possible, since a complete cure is unlikely.
