Abstract
Emerging evidence suggests women who are exposed to harmful environmental exposures, especially during certain critical periods across the lifespan, may increase their breast cancer risk. Such windows of susceptibility (WoS) occur throughout a woman’s lifetime, during which she is especially vulnerable to the effects of harmful environmental exposures. This interaction makes the reduction of harmful environmental toxicants during those time periods a priority for community health promotion. Communicating about environmental exposures and their impact on women’s health requires an assessment of sense-making around, and understanding of, the link between breast cancer and the environment. To that end, focus groups were conducted to assess the themes that emerge when women make sense of (a) their own breast cancer risk, (b) the environment-cancer connection, and (c) WoS. Results provide insight into how women understand these issues which can inform messaging strategies focused on reducing harmful environmental exposures. Implications are discussed within the context of communication efforts tailored to educate women, particularly mothers with daughters in the prepubertal and pubertal WoS who are particularly vulnerable to harmful environmental exposures.

Today, we are going be discussing breast cancer and the environment. Again, there are no right or wrong answers—we are looking for your thoughts, insights, and opinions. So, let us get started.
-
I.
There are lots of things to worry about in our lives in general and related to our health. How does breast cancer rank for you in terms of your overall level of worry? Please explain.
-
II.
When you think about breast cancer, what are the major risk factors that might contribute to someone getting breast cancer?
-
a
Are there any other factors that you think might increase someone’s risk of breast cancer?
-
b
We are also going to be talking about environmental exposures—so my next question for everyone is when you think of environmental exposures, what comes to mind?
-
i.
If you had to define it for someone, what would you say?

i.
-
a
-
III.
For our purposes today, we are going to define environmental exposures as “contact with substances, such as chemicals or small particles, through the air we breathe, the food we eat, the water we drink, and things we touch and put on our skin.”
-
a
Now that you know how we are defining environmental exposures, what types of specific concerns do you have about environmental exposures and breast cancer?
-
b
Do you think that chemical exposures can increase the risk of breast cancer? What kind of chemicals are you concerned about—please name them if you can?
-
i.
How concerned are you about chemicals in food and everyday products?
-
ii.
Which chemicals or products in your home concern you?
-
iii.
Are there certain health effects that concern you?
-
i.
-
c
Throughout one’s lifespan, when are individuals vulnerable to chemical exposures?
-
i.
Are there times when one might be more vulnerable to chemical exposures? When might these times be?
-
ii.
What would you call this time frame of high risk?
-
iii.
Have you ever heard/seen the term Window of Susceptibility as it relates to breast cancer? What does it mean to you?
