Radiation therapy is a targeted therapy, where cancerous cells are directed to destroy it. This treatment damages the ability of cancer cells to replicate and spread of cancer. There are a variety of advanced methods of radiotherapy as proton beam therapy, stereo tactic radio surgery, etc.

Radiation can be defined as a cell targeted therapy using ionizing radiation to destroy cancer cells. It causes damage to the genetic make up of cells which in turn results in the cessation of growth and replication of these cells. This radiation can damage normal cells nearby. But most normal cells can recover from it. Maximum destruction of cancer cells is the goal of treatment. Radiotherapy is used to destroy a tumor or reduce the tumor to relieve symptoms.

Radiotherapy can be used independently or as a combination with chemotherapy or surgery. This is mainly done to increase the success of treatment. There are cases in which radiation is used as a symptomatic treatment or palliative treatment to relieve symptoms such as pain and improve the condition of the patient.

The effectiveness of radiation therapy for various cancers

Radiation therapy has prolonged survival of cancer patients. As in any treatment of a variety of cells respond differently to this treatment also. Radio shows the sensitivity response of cancer cells. The dose of radiation is a term used to show the amount of radiation absorbed by cancer cells. currently used unit dose is gray (Gy ).

is very sensitive cancer cells such as cancer and blood cancer stem cells are rapidly destroyed by minute doses of radiation. Moderately sensitive cells such as skin cancer cells need a higher dose of radiation. There are even cells that are resistant to fire. Melanoma and renal cell cancer are good examples. In such cases, higher doses of radiation is desirable. Medicinal densitivity of tumors differ from each other.Leukaemia could not be treated as cancerous cells spread through the body. Lymphoma can be cured if it is concentrated in one particular area. for appropriate tumers were routinely treated with curative doses of radiotherapy.

The size and issues in the treatment of cancer. The small size of tumors are more sensitive than large tumors. Different methodologies have been adopted to cancel this effect. Therapy before surgical resection is the usual way. It is widely adopted in the treatment of breast cancer. Use of neoadjuvant chemotherapy before radical radiotherapy is another way. Various drugs such as Cetuximab, cisplatin, etc. are administered before the radiotherapy.All radiosensiting drugs.
