Whois & Analysis for aapm.org

Brachytherapy is a form of radiotherapy where a sealed radiation source is placed inside or next to the area requiring treatment.

Brachytherapy is commonly used as an effective treatment for cervical, prostate, breast, and skin cancer and can also be used to treat tumours in many other body sites.

Treatment results have demonstrated that the cancer cure rates of brachytherapy are either comparable to surgery and EBRT or are improved when used in combination with these techniques.

Brachytherapy can be used alone or in combination with other therapies such as surgery, external beam radiotherapy (EBRT) and chemotherapy.

Ionizing radiation (ionising radiation) is radiation that carries enough energy to free electrons from atoms or molecules, thereby ionizing them.

Ionizing radiation is made up of energetic subatomic particles, ions or atoms moving at high speeds (usually greater than 1% of the speed of light), and electromagnetic waves on the high-energy end of the electromagnetic spectrum.

Medical physics (also called biomedical physics, medical biophysics or applied physics in medicine) is, generally speaking, the application of physics concepts, theories and methods to medicine or healthcare.

Medical physics departments may be found in hospitals or universities.

Health physics is the applied physics of radiation protection for health and health care purposes.

It is the science concerned with the recognition, evaluation, and control of health hazards to permit the safe use and application of ionizing radiation.

Health physics professionals promote excellence in the science and practice of radiation protection and safety.

Health physicists principally work at facilities where radionuclides or other sources of ionizing radiation (such as X-ray generators) are used or produced; these include hospitals, government laboratories, academic and research institutions, nuclear power plants, regulatory agencies, and manufacturing plants.

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.

Radiation therapy may be curative in a number of types of cancer if they are localized to one area of the body.

It may also be used as part of adjuvant therapy, to prevent tumor recurrence after surgery to remove a primary malignant tumor (for example, early stages of breast cancer).

Radiation therapy is synergistic with chemotherapy, and has been used before, during, and after chemotherapy in susceptible cancers.

The subspecialty of oncology concerned with radiotherapy is called radiation oncology.
