External Radiation Therapy And Sun Exposure

The most common type is called external beam radiation therapy which is radiation given from a machine located outside the body. The source of radiation can be a piece of equipment that produces the radiation like an x ray machine or it can be from radioactive materials in a container.

External radiation is usually done during outpatient visits to a hospital or treatment center.

External radiation therapy and sun exposure. External beam radiation therapy is also called external radiation therapy or teletherapy. During exposure this radiation can be absorbed by the body or it can pass completely through similar to a chest x ray. This approach can treat larger areas of the body or more than one area such as the tumour a.

A machine directs a beam of radiation through the skin to the tumour and a small amount of normal surrounding tissue. P seocttrn fkiomr sun exposure during treatment and for at least 1 year after radiation therapy is discontinued. Radiation is a strong beam of x ray energy which passes through normal organs and tissues to reach tumors.

Once radiation is discontinued use sun blocking agents with a sun protection factor spf of at least 15. Patients who have undergone chest wall radiation are even more likely to react to sun exposure. Cancer is a condition where abnormal cells increase in number and form tumors.

Avoiding sun exposure to the treated area. Cover skin with protective clothing during treatment. Rlanretex adiation poses no risk to other people for radiation.

External exposure occurs when all or part of the body is exposed to a penetrating radiation field from an external source. Lets look at route of exposurewhen we hear the words radiation exposure we generally think of radiation beaming out from a source or device and striking the outside of our bodyhowever radiation can also come from radioactive material that leaves its energy in internal organs if ingested injected or inhaled. External exposure is radiation that comes from somewhere outside the body and interacts with us.

External radiation therapy is a treatment which uses radiation to treat cancer. Radiation therapy may be curative in a number of types of cancer if they are localized to one area of the body. Radiation therapy or radiotherapy often abbreviated rt rtx or xrt is therapy using ionizing radiation generally as part of cancer treatment to control or kill malignant cells and normally delivered by a linear accelerator.

Modern machines better focus the radiation and do less damage to normal tissues so doctors can use higher doses of radiation. Radiation technology allows the precise delivery of external beam radiation therapy. Significant sun exposure can cause a recall of the radiation skin reaction even after the acute skin reaction has resolved.

Types of external beam radiation therapy include proton therapy 3 dimensional conformal radiation therapy 3d crt intensity modulated radiation therapy imrt and. If a patient is going to be outside and exposed to the sun then the radiated skin should be covered with clothing or. Note that exposure to a radiation field does not cause an individual to become radioactive.
