Chemotherapy is the the use of medicines or drugs to treat cancer. Most chemotherapy drugs enter the bloodstream and travel throughout the body to reach cancer cells in different organs and tissues .Chemotherapy drugs target and injure rapidly dividing cells, but because it is not cancer specific, both cancer cells and some normal cells are affected. Side effects are caused when normal cells are damaged. Cancer cells don’t repair easily, so they recover more slowly than normal cells. By the time your next treatment starts, your body’s normal cells have recovered but the cancer cells have not. This means that more cancer cells are destroyed with every treatment.

Hyperthermia means a body temperature that is higher than normal. High body temperatures are often caused by illnesses., such as fever. But hyperthermia also refer to heat treatment.These are 2 very different ways in which hyperthermia can be used to treat cancer: (a) High temperatures can be used to destroy small areas of cells, such as a tumor. This is called as local hyperthermia
(b) The temperature of a part of the body ( or even the whole body) can be raised a few degrees higher than normal. It helps other cancer treatment such as chemotherapy, radiotherapy or immunotherapy work better. This is called systemic hyperthermia.

Targeted therapy is a newer type of cancer treatment that uses drugs or other substances to more precisely identify and attack cancer cells, while doing little damage to normal cells.Targeted therapy is used to keep cancer from growing and spreading. To become cancer cells, normal cells go through a process called carcinogenesis (car-sin-oh-JEN-eh-sis). Cancer cells may then grow into tumors or reproduce throughout a body system.Targeted therapy disrupts this process. The drugs target certain parts of the cell and the signals that are needed for a cancer to develop and keep growing.
