In most people’s consciousness, the onset of cancer seems to be a divine attempt to take us away. Cancer, which represents despair and death, seems to be impossible to prevent, but we would like to say that cancer prevention depends on knowledge. Is it possible that people are not equal in front of cancer? Does cancer also “bully the weak and fear the tough”? When it comes to the news that “most oncologists are cured of cancer”, it seems incredible, but there is actually a reason behind it. Doctors’ bodies are no different from those of ordinary people, but they have much more health awareness and knowledge than ordinary people, and with the targeted regular medical checkups and understanding of warning symptoms, early detection of malignant tumors is not surprising. The following highlights some of the experiences of the doctors whose tumors were successfully treated. [First Line of Defense – Health Knowledge] If you understand that smoking is a predisposing factor for lung, stomach, pancreatic and bladder cancer, then you may quit smoking and take the initiative to avoid the risk of these tumors. If you know that hepatitis B is the main culprit of liver cancer in China, then you may have regular treatment, regular review and good lifestyle habits to minimize the risk of liver cancer. If you know that dark red blood stool in middle-aged and old people may be caused by intestinal cancer, then you may go for a colonoscopy and perhaps detect colorectal cancer at an early stage and get cured as a result; if you know that family history is a high-risk factor for stomach cancer, then you may go for a gastroscopy after your father passed away due to stomach cancer and perhaps you can intervene at the time of precancerous lesions. 【Second line of defense – regular medical checkups】 Regular medical checkups, of course, also apply to doctors. Take the hospital where Academician Sun works as an example, there are more than 1,000 employees in the hospital, and several cases of cancer are detected in the annual medical checkups, but basically they are in the early stage and thus have a chance to be cured. I heard that the medical examination of hospital staff is usually taken care of by the health department of the hospital, which is not open to the public. So, is there any “reserved program” for medical checkups of oncologists? What do oncologists check in their own physical examination? In fact, there is no “welfare” for doctors’ physical examination, there is no imaginary PET-CT, and there is no MRI (magnetic resonance imaging) and other so-called “advanced examination”. Generally speaking, the first major item is to draw blood, including routine blood, liver function, uric acid, blood sugar, triglycerides, cholesterol and so on. Among these tests, routine blood tests can screen for blood tumors, liver function can show the health of the liver, and the rest of the tests are mainly related to chronic diseases such as cardiovascular disease and diabetes. The second major item is imaging, including ultrasound to have a basic understanding of the entire abdominal organs, including the liver, gallbladder, pancreas, spleen, urinary and reproductive cavities. For women, a breast ultrasound will be added, and for those over 50 years old, a high-resolution CT will be added, mainly for lung cancer, which has the highest incidence among malignant tumors, and for hospitals with higher requirements, gastroscopy and colonoscopy will be recommended to exclude the most common digestive tumors: stomach and colon cancer. In contrast to ordinary people: they know less, the items they check are not targeted, and they think they can rest easy if their annual physical examinations are normal, but in fact, there is a difference between health examinations and cancer prevention examinations. With the trend of aging population, it is hard to avoid the increasing incidence of cancer, so we have to do a good job of regular targeted medical checkups as a line of defense. In addition, we would like to remind you not to underestimate such simple tests as urine routine and fecal routine. Urine routine can check whether there is any bleeding in urine, which is helpful to detect urinary tumor; stool routine plus occult blood can detect traces from stomach cancer to colorectal cancer. According to incomplete statistics, 70% of people give up routine stool examination for various reasons, compared with the current annual number of about 300,000 new colorectal cancer patients in China. Also don’t underestimate the doctor’s palpation, which includes palpation of head and neck, abdomen, breast and rectal examination, where the doctor checks whether there are lumps in head and neck, abdomen and rectum by hand touch and simple instruments. Dr. Xiao Zhang, who had breast cancer three years ago, is back in the field. Dr. Zhang’s breast cancer was self-examined. Since she had been having problems with breast enlargement for many years, she insisted on doing breast self-examination exercises once every two months. Three years ago, she felt a small lump, then did the related examination highly suspecting breast cancer, and did the surgery was really bad news, although the lump was extremely small, there was already lymph node metastasis. The third line of defense – cooperation with treatment] Do doctors themselves have any “special medicine” that is not transmitted from inside to outside? Or do doctors treat their own people with more care? How do doctors prescribe drugs for their own people? Dr. Zhang said that the whole treatment process was no different from that of an ordinary cancer patient, and there were a lot of self-paying drugs prescribed to her. For the whole treatment, she paid more than 100,000 yuan out of her own pocket. She said frankly: “I had the will to preserve my own breast and also actively communicate with the doctor, but finally chose the modified radical surgery, I never doubted every decision the breast surgeon made for me. Doctors and patients trust each other to achieve the best expectations, doctors work with more enthusiasm, and patients recover faster. In contrast to ordinary people: former Apple CEO Steve Jobs was found to have a tumor in his pancreas during a full-body physical examination in October 2003, and the maverick Steve Jobs refused the doctor’s offer of immediate surgery for some reason, choosing to believe in the so-called food therapy + herbs + acupuncture! Jobs persevered for 9 months with the “help” of herbs, using this precious time to fully prove to himself that he had believed that the treatment plan was useless! And then he was forced to undergo a long overdue surgery. More knowledge may give us more chances to prevent and cure cancer. I hope that the experience of doctors in cancer prevention and treatment can give you some inspiration, and I also hope that it can give patients confidence in facing cancer. Doctors are also ordinary people, but the reason why they have a much higher rate of success in overcoming tumors than ordinary people is largely attributed to their health awareness and health knowledge. This also reminds us that as long as we do the above, we can also get a better prognosis from it. Healthy lifestyle habits and healthy diet are the first step to prevent tumor, but many people may have been living unconsciously for most of their lives when they realize this problem, so it may be a bit of a “hate to see you later” feeling. Don’t worry, it’s never too late to establish healthy habits and learn health knowledge. Health knowledge is accumulated slowly during the day and should be obtained from regular and reliable channels, not from health product salesmen. Cancer prevention and treatment always emphasizes: early prevention, early detection and early treatment. The treatment can be handed over to professional doctors, but the two key steps of prevention and detection still depend on yourself to a large extent.
