Doctors suggest to take targeted drugs, which is just a means to treat tumors and does not mean anything wrong. Targeted drugs are one kind of anti-cancer drugs. At present, tumor as a whole has entered the era of targeted therapy, by finding the driver genes accompanying specific tumors and designing drugs for these targets, such targeted drugs are like biological missiles that can kill tumor cells precisely. Although chemotherapy drugs have more obvious therapeutic effects on tumor cells, they also have more side effects. However, treatment with targeted drugs can target the corresponding tissues and organs, cells and sub-cellular targets of human body directly, which can cause less damage to normal cells of human body and produce less side effects by drugs. Especially for post-operative patients, taking targeted drugs together with radiotherapy and endocrine therapy can improve the treatment effect to a greater extent, which is conducive to the recovery of patients and reduce the chance of recurrence and prolong the overall survival of patients. In addition, the therapeutic effect of targeted drugs varies from person to person and should be used in conjunction with the patient’s specific situation. Targeted drugs are generally more expensive, take longer to treat, and can produce drug resistance with long-term use. Therefore, when using targeted drugs, they should be used under the guidance of doctors and in strict accordance with the indications. It can be said that the introduction of targeted drugs has greatly improved the prognosis of tumors and provided more possibilities for tumor drug treatment.
