What is chemotherapy?

Chemotherapy is an abbreviation for chemotherapy, which is a treatment method that uses chemical drugs to prevent cancer cells from proliferating, infiltrating, and metastasizing until finally killing cancer cells.

Chemotherapy is the use of specific chemical drugs to interfere with the growth and division process of cancer cells. These drugs can act on different stages of the cell cycle and inhibit the key processes such as DNA synthesis and protein synthesis of cancer cells, thus achieving the purpose of inhibiting cancer cell proliferation. At the same time, chemotherapy can be used for the treatment of a variety of cancers, whether early or advanced. For some cancers with distant metastasis, chemotherapy is often one of the important treatment methods. Chemotherapy before and after surgery can also help improve the effectiveness of surgery and reduce the risk of recurrence.

It should be noted that chemotherapy drugs may cause a certain degree of damage to normal cells while killing cancer cells, resulting in a series of side effects such as nausea, vomiting, hair loss, leukopenia, etc. However, doctors usually take appropriate measures to mitigate the impact of these side effects on patients.
