Today, I would like to tell you the ten common misconceptions about tumor prevention and treatment: 1. Tumor can not be prevented or treated This is the “capitulationism” in the prevention and treatment of tumors. Tumor has been proved to be a kind of disease greatly affected by the environment, and its occurrence is closely related to the dietary structure, living habits, environmental pollution, etc. The two most important points for the prevention of malignant tumors are: no smoking, no smoking, no smoking. The two most important points for the prevention of malignant tumors are: non-smoking and reasonable diet. As early as in the early 1990s, the World Health Organization put forward the concept of three 1/3, that is, 1/3 of cancers can be prevented, 1/3 of cancers can be treated if detected at an early stage, and 1/3 of cancers can alleviate pain and prolong life. There is no need for tumor patients to be on edge. Cancer is not very far away from us, but we should be vigilant and able to face all diseases frankly in order to have a full and free life. It is impossible for tumor patients to return to the society. This is the “pessimism” in tumor prevention and treatment. Although the tumor will recur and metastasize, it is not a lifelong disease and can be recovered. Most patients with malignant tumors are cured if they do not have recurrence for 5 years. This is because if the subclinical metastatic foci of the tumor have not been eliminated, after 5 years of proliferation, it should have reached the degree of diagnosis, and if no more cancer cells are found after 5 years, the patient can be considered cured. Resection of cancer is cured, and radiotherapy and chemotherapy have too many toxic side effects. This is “blind optimism” in tumor prevention and treatment. Many patients and their family members do not understand the characteristics of metastatic and invasive tumors and think that surgical resection of the tumor is considered cured, which often delays the follow-up treatment of the patients. There are also many patients and their family members who heard that radiotherapy and chemotherapy have serious toxic side effects and they are unwilling to accept the treatment and let the tumor develop. Although radiotherapy and chemotherapy can damage normal cells while killing cancer cells, for subclinical metastatic foci that still exist in the body after surgery, only chemotherapy can kill it. For the various side effects of radiotherapy and chemotherapy, there are many medicines available to prevent and alleviate them. Moreover, the majority of medical oncologists have mastered the techniques of preventing and dealing with the toxic side effects of radiotherapy and chemotherapy. 4. Go to some non-oncology specialties for treatment This is the “liberalism” in tumor prevention and treatment. Tumors pay attention to scientific, reasonable, standardized and systematic comprehensive treatment, especially the first treatment often plays a decisive role. Many small hospitals do not have the conditions and equipments to carry out comprehensive treatment of tumors, but they are driven by economic interests to treat tumors; some non-oncology medical staffs have insufficient knowledge and clinical experience in diagnosis and treatment of tumors, but they also carry out radiotherapy and chemotherapy. An irregular surgery or an ill-designed radiotherapy or chemotherapy program may lead to tumor residue or drug resistance, which will bring great difficulties to the next treatment and even lead to the failure of the whole treatment. 5. Believing in “ancestral secret prescription” or “single prescription” This is the “opportunism” in tumor prevention and treatment. Some patients or their family members often listen to some rumors, spend a lot of money to buy the so-called “ancestral secret formula” and “single prescription”, and even pray to God for a miracle. These “cancer cure professionals” and “ancestral family” not only have not received formal medical education, but also have no medical knowledge at all. I believe that there are many examples of people who have delayed treatment due to their belief in “secret prescriptions”. Timely to the regular hospital to seek medical help is the king. Doctors and family members conceal their illnesses This is “individualism” in tumor prevention and treatment. Doctors don’t tell patients the real condition, which was once considered to be the protection of patients, but the consequence is that patients don’t actively cooperate with the treatment, and it is difficult to achieve the best results. Some patients’ family members do not dare to let the patients go to oncology specialists for treatment, and they are not willing to carry out the necessary radiotherapy and chemotherapy after surgery. When the tumor recurs and metastasizes and is then treated again, there is no way back. 7. A program and a kind of traditional Chinese medicine can cure all tumors. This is the “dogmatism” in the prevention and treatment of tumors. This is the “dogmatism” in tumor prevention and treatment. A certain doctor has cured a certain patient, so many patients tend to rush to him, thinking that their diseases can be cured by this doctor. In fact, tumors are complicated, and curing one patient does not mean that all patients can be cured. In addition, many patients blindly believe that a certain traditional Chinese medicine can cure all diseases, and most of the pCms can only play an auxiliary role, if they want to rely on a certain pCm to treat tumor, it is a big mistake. It is a big mistake if you want to rely solely on a certain proprietary Chinese medicine to treat tumor. 8. The results of experimental research are regarded as clinical efficacy, which is the “adventurism” in the prevention and treatment of tumors. This is “adventurism” in tumor prevention and treatment. The so-called “experimental results”, more than 95% of which are the results of animal experiments, are not the results of clinical application on patients. There are differences between humans and animals, and not all drugs that are effective for animals are effective for humans. Even if the formal media reported that a certain anti-cancer results won the national, provincial and ministerial level scientific and technological progress awards, but also mostly in the laboratory research stage, there is still a long way to go from clinical application. 9, blindly superstitious experts, do not understand that experts also have focus This is the “heroism” in tumor prevention and treatment. There are many excellent experts in certain fields of tumor treatment with profound attainments. For example, there are surgical oncologists specializing in surgical treatment, medical oncologists engaging in chemotherapy, endocrine therapy, biological therapy, nutritional support therapy and radiotherapists engaging in radiotherapy. Thus, one should not blindly recognize a certain expert, but should choose the corresponding expert according to the different diseases and treatment methods. Cancer pain does not use painkillers. This is the “conservatism” in tumor prevention and treatment. Pain is an important issue that affects the survival quality of patients with advanced tumors. However, many patients and their families, even including a few non-oncology medical professionals, wrongly believe that tumor patients should not use painkillers as a last resort.
