Dental disease and extractions; patients with poor oral hygiene and dental disease prior to radiation, including edentulous patients and those with dentures, are more susceptible to developing ORN. [ 3 ] [ 9 ] Diseased teeth near the radiation field may need to be extracted, [ 23 ] and should be evaluated prior to radiation treatment.
[3] [4] Cancer can be difficult to diagnose because its signs and symptoms are often nonspecific, meaning they may be general phenomena that do not point directly to a specific disease process. [5] In medicine, a sign is an objective piece of data that can be measured or observed, as in a high body temperature (fever), a rash, or a bruise. [6]
Any type of ionizing radiation can cause burns, but alpha and beta radiation can only do so if radioactive contamination or nuclear fallout is deposited on the individual's skin or clothing. Gamma and neutron radiation can travel much greater distances and penetrate the body easily, so whole-body irradiation generally causes ARS before skin ...
Radiation therapy sources can cause beta burns during exposure of the patients. The sources can be also lost and mishandled, as in the Goiânia accident, during which several people had external beta burns and more serious gamma burns, and several died. Numerous accidents also occur during radiotherapy due to equipment failures, operator errors ...
Ultrasound is applied using a transducer or applicator that is in direct contact with the patient's skin. Gel is used on all surfaces of the head to reduce friction and assist transmission of the ultrasonic waves. Therapeutic ultrasound in physical therapy is alternating compression and rarefaction of sound waves with a frequency of 0.7 to 3.3 ...
Prostate cancer is the second cause of cancer and the most common malignancy associated with deaths in men worldwide. [66] Current methods of treatments are invasive resection therapy, radiation therapy, and prostatectomy that can cause complications such as incontinence, impotence, and damage to surrounding organs and tissues.
T-cells attack cancer cells and cause them to become inflamed and die, but your body makes a limited amount of T-cells, and if there is too much cancer to fight, the T-cells can’t keep up ...
Clear evidence establishes ultraviolet radiation, especially the non-ionizing medium wave UVB, as the cause of most non-melanoma skin cancers, which are the most common forms of cancer in the world. [40] Skin cancer may occur following ionizing radiation exposure following a latent period averaging 20 to 40 years.
