While breast cancer screening tests are accepted as safe – and we definitely wouldn’t want to scare anyone off from a potentially life-saving test – they do have some risks associated with them. The most obvious being the exposure to low doses of ionizing radiation, which in itself is a risk factor for breast cancer. X-ray mammography can also give false positive and negative results. In the quest for a safer, more accurate alternative, Dutch researchers have provided proof of concept that photoacoustic imaging can be used to detect and visualize breast tumors.
