There are many ways to treat cancers. In addition to the more familiar surgical methods, chemotherapy (chemo) and radiation therapy (radiotherapy), hormone therapy, targeted therapy and immunotherapy have become more and more popular in recent years. Patients generally adopt combination therapies to cope with the diseases, such as combining surgery with chemo or radiotherapy, to improve the curative effect. At the same time, cancer treatment has become more precise and personalized. Doctors no longer rely solely on the stage or type of cancer to determine the treatment method, but use efficient and advanced genetic testing to distinguish the characteristics of cancer cells and their genetic combinations, and then select the most specific new generation of drugs for treatment.
