Better radiation protection urged for female HCWs
Standard protective equipment does not fully protect breast tissue from radiation and regularly exposed female healthcare workers need better protection to help minimise their risk of developing breast cancer, according to anLead author Isobel Pilkington, a core surgical trainee in Wessex Deanery, and colleagues, pointed out that ionising radiation is a known human carcinogen, and breast tissue is highly radiation sensitive.
As an example, however, studies of female US orthopaedic surgeons have reported a 2.9- to 3.9-fold increase in the prevalence of breast cancer, compared with an age-matched female population, whereas female plastic and urological surgeons with similar lifestyles and pregnancy histories did not share this augmented risk. Increased rates of breast cancer have also been found in cohorts of radiological technicians.
There has also been "historical underestimation of the impact of ionising radiation on breast tissue," the authors noted, such that in 2007 the International Commission on Radiation Protection revised its guidelines to double the relative detriment of ionising radiation for breast cancer. However, in contrast to other radiation sensitive areas such as the eyes and thyroid, "no occupational dose limits exist for breast tissue".
