In medicine, proton therapy, or proton radiotherapy, is a type of particle therapy that uses a beam of protons to irradiate diseased tissue, most often to treat cancer.The chief advantage of proton therapy over other types of external beam radiotherapy is that the dose of protons is deposited over a narrow range of depth; hence in minimal entry, exit, or scattered radiation dose to healthy ...
The Therac-25 was designed as a machine controlled by a computer, with some safety mechanisms switched from hardware to software as a result. AECL decided not to duplicate some safety mechanisms, and reused modules and code routines from the Therac-20 for the Therac-25. The first prototype of the Therac-25 was built in 1976 and was put on the ...
Localized hyperthermia treatment is a well-established cancer treatment method with a simple basic principle: If a temperature elevation to 40 °C (104 °F) can be maintained for one hour within a cancer tumor, the cancer cells will be destroyed. [11] The schedule for treatments has varied between study centers.
Cancer immunotherapy (immuno-oncotherapy) is the stimulation of the immune system to treat cancer, improving the immune system's natural ability to fight the disease. [ 1 ] It is an application of the fundamental research of cancer immunology (immuno-oncology) and a growing subspecialty of oncology. Cancer immunotherapy exploits the fact that ...
The good news is that, when caught early, endometrial cancer is highly treatable. “Treatment for endometrial cancer typically involves surgery and may be followed by radiation therapy ...
Patti Scialfa is opening up for the first time about her six-year journey with multiple myeloma.. The longtime E Street Band member was diagnosed with the blood cancer in 2018, and has since faced ...
But the phenomenon overall is rare and has been scarcely studied: Some research shows less than 1% of patients have refused all types of conventional treatment for a cancer diagnosis; regarding ...
Radiation-induced cancer. Exposure to ionizing radiation is known to increase the future incidence of cancer, particularly leukemia. The mechanism by which this occurs is well understood, but quantitative models predicting the level of risk remain controversial. The most widely accepted model posits that the incidence of cancers due to ionizing ...
