Radiation Therapist

Definition

radiation is a powerful form of energy generated by radioactive materials, such as cobalt, or by special equipment, such as an atomic particle accelerator (linear).

especially radiation to kill cells that divide rapidly and cell networks are difficult untu repair their DNA (nuclear material). cancer cells divide more frequently than normal cells and are often unable to repair the damage caused by radiation. therefore, cancer cells are more likely to be killed by radiation than normal cells. however, cancer cells vary in how easy it is to be killed by radiation, some cells are very resistant and can not be effectively treated with radiation.

Types of Radiation therapist

The most common form, external beam radiation therapist using gamma radiation generated by a linear accelerator. light radiation is rarely used electro and protons.proton radiation light, which can be focused on specific areas, very effectively treat certain cancers in areas of damaged normal tissue is important, such as eyes, brain, or spinal cord. all types of external beam radiation or focused on specific areas of organs that contain cancer. to avoid normal tissue too much shining, a few streaks of light used and the surrounding tissue is protected as much as possible. new technology in external beam radiation, radiation therapist called intensity module (IMRT).

External radiation therapist is given as a series of balanced dose distribution over the long term. This method increases the lethal effects of radiation on cancer cells while reducing the toxic effects on normal cells. reduced the toxic effects because normal cells can repair themselves quickly between doses where cancer cells can not.especially, one who received radiation doses every day over a period of 6 to 8 weeks. to ensure that in the same area is treated each time, the person is properly positioned using foam pads or other tools.

Oon the other radiation therapist, radioactive material is injected into the vessels likely to flow to the cancer (eg, radioactive iodine, used in the treatment of thyroid cancer).Another way to use small pellets of radioactive material placed directly into the cancer.

Recent radioactive material has been mixed with a protein called a monoclonal antibody, which look for cancer cells and join them. radioactive material incorporated into the core antibody in cancer cells and destroy them.

Use

Radiation therapist plays an important role in curing many cancers, Hodgkin's lymphoma, non-Hodgkin's lymphoma early stage, squamous cell cancer of the head and neck, seminoma (testicular cancer), prostate cancer, early stage breast cancer, cure rates are very important together with radiation therapist case surgery.sometimes, combined radiation therapist in the form of other treatment. certain types of chemotherapy drugs, such as cisplatin, increases the effectiveness of radiation therapist.

radiation therapist can reduce symptoms when not possibly recover
