Scripps Florida Scientists Uncover Inflammatory Circuit That Triggers Breast Cancer
The first author of the study, “IL6-Mediated Suppression of Mir-200c Directs Constitutive Activation of an Inflammatory Signaling Circuit That Drives Transformation and Tumorigenesis,” is Matjaz Rokavec of Scripps Research. Other authors include Weilin Wu, also of Scripps Research.
The study was supported by the National Institute of Health, the United States Department of Defense, the Florida Department of Health, and Frenchman’s Creek Women for Cancer Research.
Breast cancer risk and lifestyle choices
Not having children or having them later in life: Women who have had not had children, or who had their first child after age 30, have a slightly higher risk of breast cancer. Being pregnant many times and at an early age reduces breast cancer risk. Being pregnant lowers a woman’s total number of lifetime menstrual cycles, which may be the reason for this effect.
Recent use of birth control pills: Studies have found that women who are using birth control pills have a slightly greater risk of breast cancer than women who have never used them. This risk seems to go back to normal over time once the pills are stopped. Women who stopped using the pill more than 10 years ago do not seem to have any increased risk. It’s a good idea to talk to your doctor about the risks and benefits of birth control pills.
Using hormone therapy after menopause: Post-menopausal hormone therapy (PHT) has been used for many years to help relieve symptoms of menopause and to help prevent thinning of the bones (osteoporosis). This treatment goes by other names, such hormone replacement therapy (HRT), and menopausal hormone therapy (MHT).
