Ionizing radiation therapy in dermatology

Production of in vitro haploid plants from in situ induced haploid embryos in winter squash (Cucurbita maxima Duchesne ex Lam.) via irradiated pollen

“…Irradiation efficiency influences from oxygen and water contents of tissue (Bernstein et al 1993), division volume of cell (Tokarek et al 1994) and also type of radiation (Goldschmidt et al 1994). Although the same irradiation procedure was followed in our previous work, the best result was obtained from 25 to 50 Gray gamma ray doses in summer squash (Kurtar et al 2002).…”

Medical radiation exposure and breast cancer risk: Findings from the Breast Cancer Family Registry

“…Although radiation has been used to treat a variety of dermatologic conditions, 38 acne-related radiotherapy is not generally recognized as a risk factor for breast cancer. The present finding of a non-significant 2-fold increased risk of breast cancer (OR 5 2.27) is consistent with findings from 3 studies that also relied on selfreported radiation exposure data and reported increased risks of similar magnitude.…”

Therapeutic Ionizing Radiation and the Incidence of Basal Cell Carcinoma and Squamous Cell Carcinoma

“…17 More highly fractionated doses of ionizing radiation, involving moderate doses for each individual fraction, is also more carcinogenic in animal models. 1 Data from this population-based case-control study indicate that persons previously exposed to therapeutic ion-izing radiation have an increased risk for BCC and SCC. Our data also suggest that SCC risk following irradiation may be highest in persons with a sun-sensitive phenotype.…”

“…1 Implicated treatments include radiotherapy of inflammatory dermatoses such as eczema, psoriasis, acne vulgaris, and tinea capitis. 2,3 Additionally, an increased risk of BCC has been related to ionizing radiation treatment of goiters, 4 ankylosing spondylitis, [5][6][7][8] acute lymphocytic leukemia, and astrocytoma.…”
