Women who are diagnosed with breast cancer are more likely to develop a second cancer in a different part of the body, a Spanish study has found.
The researchers said the increased risk could be due to the similar risk factors involved in both cancers, or the side-effects of treatment received by breast cancer patients.
Compared to the general population, women under the age of 50 who had previously suffered from breast cancer were almost twice as likely to be diagnosed with cancer, the study says. In women over the age of 50 who had previously had breast cancer, a second cancer was 29% more likely.
The study appears in the journal Gynecologic Oncology.
