There are many misunderstandings in the process of cancer treatment, which delay the best treatment time and affect the survival rate and quality of life of patients. In the minds of many people, suffering from cancer means that life is about to end. Whenever people say “so-and-so is suffering from cancer”, the speaker must be grief-stricken and the hearer must feel frightened. The public’s general fear of tumor makes many patients and their family members “rush to the doctor” and blindly believe in some informal therapies and health foods about tumor, thus entering the misunderstanding of tumor treatment. Some “folk Chinese doctors” believe that tumor is “formed by the gathering of poisonous gas” and the treatment method is “attacking poison with poison”. They use large doses of toxic Chinese medicine, such as snake, scorpion, heavy metal and mineral, ocimum and strychnine, etc., and take them internally and apply them externally, the more toxic the better, so as to kill the tumor before it is too late. This treatment method is actually “suicide therapy”, the tumor is not killed, people have been killed first: liver, kidney function is bound to be seriously damaged, until failure. 2. Blindly believe in folk secret prescriptions In today’s highly developed science and technology, there are still people who believe in ancestral secret prescriptions for cancer treatment for many generations. In fact, some cancer treatment “professionals” and “ancestral families” not only have not received formal medical education, but also do not even have some medical common sense, so many patients have been cheated, wasted money and lost the best treatment time. 3.Believing or relying on certain nutritional products The misleading propaganda of some health food products “cure all cancers” makes some patients and their family members who lack discernment believe in them and take them blindly for a long time without seeking medical treatment, which delays the treatment time. In fact, these supplements can only be used as adjuvant treatment for nutritional support, and must be used in conjunction with traditional Chinese medicine and radiotherapy to achieve certain curative effects. Moreover, the cost of using them as nutritional support for adjuvant treatment is much higher than regular treatment, which is beyond the reach of many patients. Some patients think that malignant tumor is ultimately death, so it is better to spend the money on eating, drinking and playing in the mountains. In fact, malignant tumors are not incurable. Many malignant tumors can be cured in early stage through regular treatment such as surgery, radiotherapy and chemotherapy, and some malignant tumors can extend their survival period and tumor-free survival period after treatment. Therefore, patients and their family members should first understand the relevant knowledge and current treatment methods and levels, have confidence in overcoming cancer and do not give up treatment easily. Many patients and their family members think that cancer is cured after surgery, but they do not understand that malignant tumors are metastatic and invasive, and can spread to the whole body through lymphatic and blood channels. Blind optimism delays the follow-up treatment of patients and eventually affects their quality of life. There are also many patients and their families who heard that chemotherapy and radiotherapy have serious toxic side effects and are unwilling to accept the treatment and let the tumor develop. In fact, with the development of medical science in recent years, the main toxic side effects of radiotherapy and chemotherapy can be completely avoided or greatly reduced, and most of the oncologists have mastered the technology of preventing and dealing with toxic side effects of radiotherapy and chemotherapy. At present, the best tumor treatment method is recognized by international and domestic consensus as comprehensive treatment. It is the scientific combination of surgery, radiotherapy, drugs (chemotherapy), immunotherapy, endocrine therapy and traditional Chinese medicine to achieve the best clinical effect. Some patients found to have malignant tumor in their body, their family members went to the hospital to find some famous oncologists. In fact, there are many excellent oncologists in each big hospital, who have deep attainments in some fields of tumor treatment, such as surgical oncologists specializing in malignant tumor surgery, medical oncologists engaged in chemotherapy, endocrine therapy, biological therapy, nutritional support therapy and symptom reduction therapy of malignant tumor and radiotherapy experts. Therefore, one should not blindly identify a certain expert, but should choose the corresponding expert according to the difference of disease and treatment method. Many people think that they should not disclose the real condition to the patients themselves so that the patients can not bear the pressure. However, experts believe that the treatment of tumor cannot be solved by a single means, so there is a long cycle process. If patients are informed of the part of their condition and given the greatest encouragement and hope, they can fully cooperate with the treatment and increase their confidence, which can obviously improve the efficacy of treatment and also increase the ability to resist disease and side effects. 8, no longer return to the hospital to review after discharge Some patients think they are cured after the symptoms are relieved or the lump disappears, and do not follow up as required, as a result, relapse or distant metastasis occurs soon, and the condition deteriorates, so that all the treatment is abandoned. Therefore, it is very necessary to review regularly and continue treatment, especially for patients whose symptoms have improved. Expert advice: the incidence of malignant tumor is still high, and there is no special method that can completely cure cancer, only through early detection, early diagnosis and scientific and reasonable comprehensive treatment can we overcome cancer to the maximum extent, so correcting misunderstanding is also the most urgent task to prevent and treat tumor. Tumor patients can only get out of the misunderstanding of seeking medical treatment, choose regular hospitals, receive systematic and comprehensive treatment combining Chinese and Western medicine, radiotherapy and chemotherapy, and internal and external treatment, and insist on complete cure is the wise thing to do.
