No matter what route of administration (oral administration, intravenous administration and body cavity administration, etc.). ), chemotherapy drugs will spread to most organs and tissues of the whole body with blood circulation.

About 70% of cancer patients need radiotherapy in the process of treating cancer, and about 40% of cancer can be cured by radiotherapy. Radiotherapy plays an increasingly prominent role in tumor treatment and has become one of the main means to treat malignant tumors.
