History and status of x-ray mammography.

Mammography is a relatively recent addition to the array of x-ray services available for the detection, diagnosis, and staging of cancer. Technological advances over the past two decades have led to substantial improvements in the quality of mammographic images and reductions in patient doses of more than an order of magnitude. Today x-ray mammography is used not only to characterize suspicious regions of breast tissue discovered by physical examination, but also to screen asymptomatic women for the early detection of breast cancer. National programs have been established to help ensure high quality images, accurate interpretations, and efficient utilization of x-radiation in the detection and diagnosis of breast cancer. In all of the advances that have lead to widespread utilization of mammography, physicists have played a substantial role.

The question of health effects from exposure to electromagnetic fields.

Possible health effects of exposure to low-intensity electric and magnetic fields (EMFs) are receiving increased attention in the scientific literature and, especially, in the public media. Laboratory research at the cellular and whole animal level has demonstrated various biological effects that may be related in some manner to the effect of EMF exposure on people. However, the exact mechanisms of this relationship are far from clear. The studies suggest that EMFs might be cancer promoters but are unlikely to be cancer initiators. At the level of human epidemiology, approximately 50 studies have examined the possible correlation of EMF exposures with adult and childhood cancers. Although the possibility of a correlation is weak, it cannot be discounted, and further research is needed. In the meantime, a practice of "prudent avoidance" of prolonged exposure to EMFs is warranted.
