When chemotherapy is mentioned, many people think of vomiting, hair loss, fatigue and weakness, and feel very terrible, so many patients reject chemotherapy. In fact, modern medicine has been greatly improved compared to the past. Now there are very effective anti-emetic drugs, which can be used before chemotherapy and have a very good preventive effect on vomiting. In addition, not all patients vomit. Most patients only have a reduced appetite during and for a short time after chemotherapy. There are also some patients, especially men, whose diet is largely unaffected. Some patients, especially young women, are more sensitive and often have psychological factors, such as feeling nauseous at the sight of an infusion bottle or hearing about chemotherapy. Such patients should adjust their mindset more while strengthening the drug antiemetic treatment, and family members should not talk too much with the patient about the side effects of chemotherapy, but rather to reduce her psychological burden. Hair loss is also a concern for many patients. In fact, not all chemotherapy drugs will cause hair loss, for example, platinum oxalate and fluorouracil used in chemotherapy for intestinal cancer patients will not cause significant hair loss. Even if hair falls out, it can be restored and many patients have new hair growth with better texture. Many of my patients have gone through multiple chemotherapy treatments and still managed to maintain a good level of physical strength. In fact, due to the physical exertion caused by tumor growth, patients feel tired and weak, poor appetite, and some patients suffer from pain caused by bone metastasis of tumor, which affects their daily life. After effective treatment physical strength is restored, appetite is improved, and pain is significantly reduced. Therefore, effective chemotherapy does not bring pain to patients, but solves it. A breast cancer patient I treated, who already had difficulty walking due to metastasis in the thoracic and lumbar spine at the time of initial consultation, has been riding a bicycle and climbing stairs for more than 4 years now after chemotherapy and endocrine therapy without any problem. Therefore, do not give up the chance of effective treatment because of the fear of chemotherapy. Especially for postoperative patients, postoperative chemotherapy is more important to cure the disease. With more effective drugs, good psychology and close cooperation between doctors and patients, chemotherapy is not scary.
