Chemotherapy is the application of chemicals to cancer cells in order to destroy or limit their growth. The medications are known as cytotoxic, which implies they are harmful to cells (cyto). Some of these pharmaceuticals are created entirely in a laboratory, while others are derived from natural sources such as plants. Depending on the type and stage of cancer being treated, chemotherapy can be delivered via mouth, injection, infusion, or skin application. It can be used alone or in combination with other treatments such surgery, radiation, or biologic therapy. Chemotherapy administration is always based on the therapeutic goals as well as the potential hazards and benefits to the patient. With these objectives in mind, the choice of a chemotherapy plan is made.
A single chemotherapy agent or a mix of treatments may be used to treat you. Chemotherapy medications come in a variety of forms, each of which eliminates or shrinks cancer cells in a unique way.
The chemotherapy medications you receive are determined by the sort of cancer you have. Because different medications function on different forms of cancer, this is the case. Chemotherapy is sometimes the only option, but you may also need surgery, radiotherapy, or other pharmacological regimens.
