What is chemotherapy? What is the difference between chemotherapy and radiotherapy?
The difference between chemotherapy and radiotherapy is that chemotherapy uses chemical drugs (including endocrine drugs) to treat malignant tumors. Anti-cancer drugs are quickly distributed throughout the body after entering the body, which can kill both local tumors and distant metastatic tumors, so chemotherapy is a systemic treatment. The effect of chemotherapy depends on the type and condition of the tumor, some can be cured, and more is to inhibit the growth and spread of the tumor. Chemotherapy is the only alternative therapy for some tumors. In more cases, chemotherapy is combined with surgical resection and radiotherapy. Chemotherapy is a treatment method that uses chemical drugs to kill tumor cells, inhibit the growth and reproduction of tumor cells and promote the differentiation of tumor cells. It is a systemic therapy with therapeutic effect on primary focus, metastatic focus and subclinical metastatic focus.
Radiotherapy is radiotherapy, which refers to the elimination of lesions through radiation. As an important means to treat malignant tumors, radiotherapy can produce good results for many cancers.
