Chemotherapy is a systematic, drug-based treatment method aimed at targeting and destroying rapidly dividing and spreading cancer cells. The drugs used in this treatment damage cancer cells by preventing their growth and proliferation. Chemotherapy can be administered alone or in various drug combinations to achieve higher efficacy. Therefore, chemotherapy regimens may include more than one drug.

Chemotherapy, which can halt the progression of cancer and destroy cancerous cells, is one of modern medicine's powerful and effective treatment methods. However, it can lead to various side effects depending on the stage of cancer and the patient's general health condition. These side effects can vary from person to person.

Administered alongside radiotherapy and other diverse treatment methods, the primary goal of chemotherapy is to eliminate cancer cells and prevent the spread of the disease (metastasis).
