Secondhand cigarette smoke causes breast cancer

Nonsmoking women exposed to intensive passive smoking were 32% more likely to develop breast cancer compared to those who were not exposed to passive smoking.

What did the study find?

  • A strong association between cigarette smoke exposure and elevated risk for breast cancer
  • Early and long exposure to smoke was linked to greater risk of breast cancer
  • The risk of breast cancer increased by smoking persisted for up to 20 years
  • Another study led by G. Nagel of Ulm University in Ulm, Germany and colleagues and published in Breast Cancer Research and Treatment found those who had high dietary intake of vitamin C and dietary beta-carotene
    (only available in plant-based foods), were 12% and 21% less likely to develop breast cancer respectively
