Chemotherapy consists of using a combination of drugs that can destroy cells in order to eliminate cancer cells. Although it has the ability to eradicate cancer, it also damages healthy cells and creates side effects to consider. Chemotherapy is given in cycles of active and rest administration. The route of administration is by intravenous infusion or oral tablets.

Radiotherapy uses high doses of radiation to destroy cancer cells. The rays are usually directed at a region of the body that is particularly affected by the cancer. The treatment can last several weeks.

Targeted therapy works by detecting signals associated with cancer cells that are not present in healthy cells. Some examples are:

• Monoclonal antibodies: artificial antibodies that recognize cancer cells.
• Tumor growth inhibitors: detect and block tumor growth.
• Tyrosine kinase inhibitors: blocks signals that tell cancer cells to multiply

Immunotherapy uses biological agents to stimulate your own immune system to more efficiently identify and defend against cancer. An example of this is CAR T-cell therapy, in which your own T cells are genetically modified to find and destroy cancer cells.

Hormone therapy is a cancer treatment that slows or stops the growth of cancer that uses hormones to grow. Hormone therapy is also called endocrine therapy.

Cancer surgery is an operation or procedure to remove a tumor and possibly some surrounding tissue by mechanical cutting, cold, or heat.
