Despite all the money and time researchers have devoted to the study of breast cancer recurrence, predicting when and why the disease might resurface is still largely a guessing game.
Professionals are getting an understanding of how breast cancer might reoccur, though. As the primary cancer is treated, so-called "seed cells" can migrate out of the breast to other parts of the body. Wherever those seeds end up, the cancerous cells can lie dormant—sometimes for years—before triggering a new and often aggressive outbreak of the disease.
While experts are still sorting out the exact mechanisms underlying recurrence, research has begun to sift out those lifestyle changes and behaviors that lower your risks—and those that don't seem to make much difference.
