Younger generations are being diagnosed with breast, pancreatic, liver and other cancers earlier at higher rates than previous generations — and are dying more often, new research warns.
Radiation-induced cancer. Exposure to ionizing radiation is known to increase the future incidence of cancer, particularly leukemia. The mechanism by which this occurs is well understood, but quantitative models predicting the level of risk remain controversial. The most widely accepted model posits that the incidence of cancers due to ionizing ...
