Monday's health links - on Tuesday

Sorry - but yesterday was Thanksgiving here in Canada. I hope everyone was able to take some time to be with, or think of, the people for whom they are thankful.

1. A new study links dense breasts to  an increased risk for recurrence in the other breast.
2. Sexual problems after breast cancer are common, but are aromatase inhibitors making it worse?
3. Last week, I gave some friends from my sons' school permission to use MY chemo brain to excuse their own mental failings (a la, "Gee, I spent too much time talking to Cyn on the playground today and now I have chemo brain!"). But what is chemo brain? A study suggests even patients who do not go through chemo experience loss of memory or confusion.
4. There ARE things you can do to lower your risk for breast cancer, and now a study says this is true even for women with a family history.The study says, regardless of a family connection, breast cancer risk drops if you do three things:
1. Exercise regularly  - 20 minutes of moderate to vigorous exercise, 4 times a week
2. Consume alcohol moderately - less than 7 drinks per week
3. Maintain a healthy weight - a body mass index (BMI) between 18.5 and 24.9.
