Supporting Tailored Approaches to Reducing Tobacco – Decreasing Breast Cancer Incidence, or START, is a program of research dedicated to developing health messages and other strategies to address the issue of tobacco exposure among adolescents as a modifiable risk factor for breast cancer.
Studies show that breast tissue, in its growth stage during puberty and before first pregnancy, is highly sensitive to exposure to carcinogens. Many young adolescent girls continue to take up smoking, and the average age at first pregnancy is older than in the past, thus potentially extending the period of vulnerability. In addition, adolescent girls who are exposed to second hand smoke on a regular basis are also at risk.
Because most other established risk factors for breast cancer are not modifiable (e.g., family history, age at menarche), and tobacco exposure impacts the lives of many young women, reducing tobacco exposure represents an important untapped opportunity to decrease breast cancer incidence. To date, there have been few efforts to raise awareness of the connection between active smoking and second hand smoke to risk factors for breast cancer.
Reaching out to this population through the development of new health messages tailored to both genders about this modifiable risk factor for breast cancer is now paramount.
