Fatigue caused by the cancer or its treatment often resolves if treatment is successful. However, some patients experience long-term or chronic fatigue. When strict definitions are used, about 20% of long-term, disease-free cancer survivors report fatigue. [2] Under looser definitions, up to half of cancer survivors report fatigue. [2]
Chronic radiation syndrome (CRS), or chronic radiation enteritis, [1] [2] is a constellation of health effects of radiation that occur after months or years of chronic exposure to high amounts of radiation. Chronic radiation syndrome develops with a speed and severity proportional to the radiation dose received (i.e., it is a deterministic ...
Radiation therapy is used mainly in the treatment of cancer. Radiation therapy can be used to cure, care or shrink tumors that are interfering with quality of life. Sometimes radiation therapy is used alone; other times it is used in conjunction with chemotherapy and surgery.
Post-exertional malaise (PEM), sometimes referred to as post-exertional symptom exacerbation (PESE) [1] or post-exertional neuroimmune exhaustion (PENE), [2] is a worsening of symptoms that occurs after minimal exertion. It is the hallmark symptom of myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) and common in long COVID and ...
Acute radiation syndrome (ARS), also known as radiation sickness or radiation poisoning, is a collection of health effects that are caused by being exposed to high amounts of ionizing radiation in a short period of time. [1] Symptoms can start within an hour of exposure, and can last for several months.
The effects of the 1979 Three Mile Island nuclear accident are widely agreed to be very low by scientists in the relevant fields. The American Nuclear Society concluded that average local radiation exposure was equivalent to a chest X-ray and maximum local exposure equivalent to less than a year's background radiation. [1]
The goal of space radiation research is to estimate and reduce uncertainties in risk projection models and, if necessary, develop countermeasures and technologies to monitor and treat adverse outcomes to human health and performance that are relevant to space radiation for short-term and career exposures, including acute or late CNS effects ...
Management of ME/CFS (myalgic encephalomyelitis/chronic fatigue syndrome) focuses on symptoms management, as no treatments that address the root cause of the illness are available. [ 1 ] : 29 Pacing, or regulating one's activities to avoid triggering worse symptoms, is the most common management strategy for post-exertional malaise .
