Hypopituitarism commonly develops after radiation therapy for sellar and parasellar neoplasms, extrasellar brain tumors, head and neck tumors, and following whole body irradiation for systemic malignancies. [49] 40–50% of children treated for childhood cancer develop some endocrine side effect. [50]
In his presentation, he defined the latent period as being 1–5 years, and the formation coinciding with the period of maximum radiation dose. The recovery period was described as being 3–12 months after exposure ceased. He concluded that "CRS represents a systemic response of the body as a whole to the chronic total body exposure in man."
Osteoradionecrosis (ORN) is a serious complication of radiation therapy in cancer treatment where radiated bone becomes necrotic and exposed. [1] ORN occurs most commonly in the mouth during the treatment of head and neck cancer, and can arise over 5 years after radiation. [2]
At this time they begin exhibiting symptoms of radiation poisoning of sufficient severity to render them totally ineffective. Death follows for about half of males at approximately six weeks after exposure. Nausea and vomiting generally occur within 24–48 hours after exposure to mild (1–2 Gy) doses of radiation.
It was after this surgery that Fishel began her radiation treatment, telling the outlet at the time she was being “constantly monitored,” which included mammograms every three to six months ...
The embryo and fetus are considered highly sensitive to radiation exposure. [8] Complications from radiation exposure include malformation of internal organs, reduction of IQ, and cancer formation. [8] The SI unit of exposure is the coulomb per kilogram (C/kg), which has largely replaced the roentgen (R). [9]
Diagnosis is typically made based on a history of significant radiation exposure and suitable clinical findings. [3] An absolute lymphocyte count can give a rough estimate of radiation exposure. [3] Time from exposure to vomiting can also give estimates of exposure levels if they are less than 10 Gy (1000 rad). [3]
