Research suggests that smoking during adolescence increases the risk of breast cancer in women by 70%, particularly those who start smoking within five years of menarche. This is due to the sensitivity of human breast tissue to environmental carcinogens during periods of rapid cell proliferation, such as puberty.
A recent study published in New England Journal of Medicine found that genetically identical twin pairs had similar breast densities, while non-identical pairs had breast densities about half as similar. This suggests that genetic factors play a major role in explaining why women of the same age have different breast density.
A recent clinical trial found that tamoxifen reduces the frequency of breast cancer by a third in women at increased risk. However, tamoxifen use also increases the risk of blood-clotting complications, which may contribute to higher death rates.
A Canadian National Breast Cancer Screening Study found that annual mammography for five years had no impact on breast cancer deaths in women aged 40-49. The US Preventive Services Task Force recommends starting mammography at age 40, but evidence is considered 'fair' due to conflicting results.
