Cancer is now is one of the biggest problems all over the world, of course, China is no exception, now every year the number of newly diagnosed cancer patients in China has exceeded 4 million, and the number of people who have passed away has exceeded 2.8 million, what is the concept of this, that is, every minute we will have 7 people diagnosed with cancer, there will be 5 people who will pass away because of cancer, and every day there will be about 10,000 people who are diagnosed with cancer, so around each one of us will meet someone like that. Lung cancer, liver cancer, tumors of the upper digestive system and colorectal cancer, and female breast cancer are still the major malignant tumors in our country. Why there are more and more cancer patients around us is because everyone is living longer and longer. Now the average life expectancy in China is 75 years, so it is at the high end of our morbidity. In the past, we used to say that people live to be seventy years old, but now in China, people over the age of seventy are dying. But now there are more than 80 million people over the age of 70 in China, so the risk will be higher and higher. The number of cancer incidence will rise. Secondly, air pollution, food and so on are also relevant. According to the statistics of the United States now, 42% of men and 37% of women will encounter cancer in their lifetime, so we should know about cancer in advance, so that once the problem arises, we will be psychologically prepared, so that we won’t get sick and be deceived. In fact, there is nothing to fear from cancer, now the global cancer survival rate has been greatly improved, there are more than 35 million people living with tumors, as far as this moment on earth now there are 35 million people can be considered to have overcome the tumor, because the treatment of cancer has been revolutionized. Because there are many effective treatments for cancer, not only traditional chemotherapy, radiotherapy and surgery, but also new targeted therapies, immunotherapy, cell therapy, minimally invasive therapy and so on, which greatly improve the cure rate of cancer, some of which are revolutionary breakthroughs, we should be aware of such a situation, and we should not casually give up the treatment, and we should not think that once we hear about cancer, cancer is just like waiting for death, and we can’t do anything if we have cancer. And so on, in fact, they are all misconceptions. Secondly, there are also many misconceptions about cancer treatment. The first one is that it is purely natural and harmless, so one always thinks that artificial things are bad, natural things are good, Chinese medicine is good and chemotherapy is bad. In fact, both Chinese and Western medicines have their respective advantages in the process of tumor treatment, which should be easily discarded. The second one is starvation of cancer cells. Its theory is that cancer cells grow fast and need to eat a lot of nutrients, so let’s not eat and starve them to death. But normal cells in our body, such as brain nerve cells, also need more nutrients, so usually the person starves to death before starving the cancer cells. Of course, in the past, there are many misconceptions, such as salt to prevent cancer, salt to cause cancer, etc. There is also to emphasize that, compared with the treatment, cancer prevention and regular medical checkups are more important, such as China’s esophageal cancer, the U.S. colorectal cancer through the screening physical examination, the mortality rate has dropped significantly. Secondly, 50% of cancers are preventable and avoidable. What are the specific factors? Tobacco, alcohol, lack of exercise, poor dietary habits, lack of dietary fiber, chronic inflammation, ionizing radiation, infections, immunodeficiency, environmental pollution, etc. If these problems are solved, cancer can be returned to the state of rare diseases as well. I wish each person a healthy body and stay away from cancer.
