“Talking about cancer” is the number one attitude that most people have towards cancer. Cancer has always been a threat to human health and even life-threatening. Therefore, cancer prevention is a matter of urgency. There is generally a period when cancer should not be detected, which is also known as latent period. Once cancer appears, we should save it in time to get more treatment opportunities for ourselves. When it comes to cancer treatment, people’s first thought is “cutting it out”. The concept of surgery for tumor treatment is deeply rooted in people’s mind, but in fact, there is not only one way to treat cancer. Radiation therapy, chemotherapy and Chinese medicine are all used in cancer treatment. There are mainly 4 types of cancer treatment methods I. Surgery Applicable scope: Not all cancer patients are suitable for surgery. Generally speaking, except for malignant tumors of the hematological system (such as leukemia and malignant lymphoma), most solid tumors can be treated by surgery. In particular, early and mid-stage cancers without local and distant metastases and tumors that are generally small are suitable for surgical treatment. Risks: Surgical treatment has certain risks, such as lung cancer patients may affect respiratory function after lung lobectomy, and osteosarcoma patients may affect mobility after amputation. Chemotherapy Chemotherapy is the application of chemical drugs (including endocrine drugs, etc.) to treat malignant tumors. Chemotherapy drugs are often injected intravenously, taken orally or in other forms into the body to kill tumors. At present, there are three major types of chemotherapy drugs: traditional cytotoxic drugs, targeted drugs and biological agents. The fastest growing drug in recent years is targeted drugs, which are now available for almost all tumors except biliary tract system tumors. However, most targeted drugs cannot completely replace cytotoxic drugs now, and have to be applied in combination with cytotoxic drugs. Scope of application: Chemotherapy is for tumors that are sensitive to chemotherapy drugs such as lymphoma, leukemia and other blood system diseases, breast cancer, gastrointestinal tumors, lung cancer and reproductive system tumors. After entering the body, chemotherapy drugs will be distributed to all parts of the body and have a strong effect not only on solid tumors, but also on small invisible metastases. The effect of chemotherapy depends on the type and condition of the tumor, some of them can be cured, while more of them inhibit the growth and spread of the tumor. Toxic side reactions: The toxic side reactions of chemotherapy are mainly systemic reactions, such as bone marrow suppression, gastrointestinal reactions, such as decreased blood count, nausea, vomiting and phlebitis. With proper treatment, severe reactions such as liver and kidney function damage and cardiac function damage are not very common in clinical practice. With the continuous development of technology, the side effects of new chemotherapeutic drugs have been greatly reduced and safety has been significantly improved. Radiotherapy is a treatment method of irradiating tumor with different energy rays to inhibit and kill cancer cells. 70% of tumor patients need to receive radiotherapy at different stages of the disease process. Scope of application: Radiotherapy is mainly used for the radical treatment of relatively limited solid tumors, such as nasopharyngeal carcinoma, head and neck tumors, which are not sensitive to chemotherapy and can be cured by radiotherapy alone. For other tumors, radiotherapy is mostly used as one of the comprehensive means. Especially for patients with mid- to late-stage tumors, preoperative can make the tumor shrink in scope to achieve the effect of stage reduction and create conditions for surgery; intraoperative palliative treatment; postoperative radiotherapy for incompletely cut parts can prevent recurrence. For leukemia and other systemic tumors, radiotherapy has limited effect. Toxic side effects: The toxic side effects of radiotherapy are mainly local reactions, which are related to the radiotherapy field. For example, head and neck radiotherapy may cause dry mouth, sore throat, neck fibrosis and loss of taste function; chest radiotherapy may cause radioactive lung changes and radioactive esophagitis. With the advancement of radiotherapy technology, radioactive brain damage and paraplegia, which used to occur frequently, are less likely to occur. Chinese medicine is characterized by slow and lasting treatment, stabilizing the disease and achieving the realm of “survival with tumor”. Firstly, TCM is very useful in the prevention of tumors. Second, the use of TCM for tumor patients after surgery can adjust the immune function and reduce tumor recurrence and metastasis. Third, radiotherapy patients use traditional Chinese medicine to reduce the side effects of radiotherapy, help patients’ body recover, and relieve the damage of drugs and radiation to the body. Fourth, postoperative maintenance treatment. Fifth, for advanced tumor patients who are not suitable for Western medicine treatment, they can be treated with evidence-based treatment and use Chinese medicine to improve symptoms and reflect individualized treatment.
