Smoking increases risk of breast cancer progression in multiethnic women with breast cancer

November 06, 2017

Results showed that 164 deaths from breast cancer and 120 deaths from non-breast cancer causes occurred during follow-up.Those women who had a history of smoking or who were current smokers also had a twofold increased risk for dying from non-breast cancer related causes compared with women with breast cancer who had never smoked.

An analysis was also conducted to examine whether body mass index, molecular breast cancer subtype or menopausal status modified risk. Women who were current or past smokers and also had a HER2-negative tumor subtype had a 61 percent increased risk for breast cancer death compared with those who never smoked. Smokers with a body mass index less than 25 kg/m2 had an 83 percent increased risk for breast cancer death, and postmenopausal women had a 47 percent increased risk for breast cancer death compared with those who never smoked.

"The implication of this research is that it is important for physicians to improve smoking cessation efforts, especially among women newly diagnosed with breast cancer, in order to improve breast cancer specific outcomes and overall health outcomes," Braithwaite said.
