A new study has found that women who currently smoke or have a history of smoking have a significant increase of developing progressive forms of breast cancer and may eventually succumb to the disease.
reports, researchers examined the relationship between smoking and the risk of death among women with an aggressive form of breast cancer.
"We found that women who are current smokers or have history of smoking had a 39 percent higher rate of dying from breast cancer, even after we took into account a wide array of known prognostic factors including clinical, socioeconomic and behavioral factors," said Dejana Braithwaite of the department of epidemiology and biostatistics at the University of California, San Francisco.
Smoking has long been know to have an impact on the lungs and has been linked to other forms of cancer, but researchers are now focusing on what effect it has on breast cancer. They acknowledge that more studies must be conducted to determine its full impact on women's health.
According to the American Cancer Society, the chance of a woman developing breast cancer in her lifetime is one in eight.
