Misconception 1, gullible “ancestral secret recipe” or “single prescription” Some patients or their families often listen to some rumors, spend a lot of money to buy the so-called cure for all the tumors of the “ancestral secret recipe” and “single prescription”. Some patients or their family members often listen to some rumors and spend a lot of money to buy the so-called “ancestral secret formula” and “single formula” that can cure their tumors. These “cancer cure professionals” and “ancestral family” not only have not received formal medical education, but also have no medical knowledge at all. In the end, the patients are in financial difficulties, and their conditions become more and more complicated, which makes the original curable lesions develop into incurable advanced tumors. Misconception 2: Doctors and family members conceal the condition and give up the treatment Doctors don’t tell the real condition of patients, which was once considered as a protective measure for patients, but the consequence is that the patients don’t know their own condition, so they won’t cooperate with the treatment positively, and especially they will miss the best time for treatment. Malignant tumors are not incurable. Thus, after suffering from cancer, patients and their family members should firstly understand the relevant knowledge and the current treatment methods and levels, have confidence in overcoming cancer, and do not give up treatment easily. Myth 3: One program and one medicine can cure all tumors, and it is believed that one kind of Chinese patent medicine can eliminate a hundred kinds of cancers. Malignant tumors are not a kind of disease but a large group of diseases. Tumor treatment mostly adopts comprehensive treatment, and different tumors and different pathological types use different radiotherapy and chemotherapy programs. Many patients blindly believe that a certain proprietary Chinese medicine can cure all kinds of diseases, and there are many proprietary health care medicines with no therapeutic efficacy at all, as well as medicines without even the approval number of the word “health” and with only the approval number of internal preparations for self-production and self-marketing, which will only make the treatment worse. The more you treat, the worse it will get. Misconception 4, the experimental results as clinical efficacy Nowadays, various “anti-cancer drugs” advertisements are all over the place. Nowadays, there are a lot of advertisements of “anti-cancer drugs”, most of which claim that they have been proved by experiments to be effective against this tumor and that tumor. The so-called “experimental results”, more than 95% are the results of animal experiments, rather than clinical application. After all, there is still a long way to go before it can be applied in clinic in the laboratory research stage. Misconception 5: Cancer is cured by resection, and radiotherapy and chemotherapy have too many toxic side effects Many patients and their families do not understand the metastatic and invasive characteristics of tumors, and they think that surgical resection of tumors is a cure. Blind and ignorant optimism often delays the follow-up treatment of patients. Many patients and their families are reluctant to receive radiotherapy and chemotherapy because they have heard that they have serious toxic side effects. However, for the subclinical metastatic foci that still exist in the body after surgery (very tiny tumor cells that can be transferred to the whole body at an early stage, which are difficult to be found by current clinical diagnostic techniques), only radiotherapy and chemotherapy can kill it. Myth 6: Cancer pain does not use painkillers Pain of advanced tumors is an important issue that affects the quality of patients’ survival. However, many patients and their family members are worried about the premature use of painkillers and the ineffectiveness of painkillers when the pain worsens in the future; they are also worried about the adverse reaction of painkillers and tumor formation. The World Health Organization has developed a three-step pain relief method, which has been gradually promoted in China. Experts believe that pain relief is not beneficial, pain relief increases confidence, pain relief is also safe, pain relief is not addictive, pain relief is not extreme amount. Adequate, regular and individualized drug administration.
