Patients taking beta blockers had a lower risk of dying from cancer, according to a study by UK and German researchers.
Breast cancer is easier to fight when tumors are limited to the breast only. But when those cells move to other parts of the body and start growing, treatment becomes more difficult.
This study finds beta blockers can limit the cells' ability to spread. But, experts emphasize, more evidence is necessary before beta blockers can become a routine treatment for breast cancer.
