Concerned about the side effects of anastrozole

my doctor was the one who recommended Aromasin over Femura. I have not found any studies that discussed the steroid effect of aromasin so I don't know if there is enough steroid to make a difference.

There are two types of aromatase inhibitors based on their structure:
- Steroidal inhibitors, such as exemestane (Aromasin)
- Nonsteroidal inhibitors, such as the anastrozole (Arimidex) and letrozole (Femara)

Here is one study comparing them:
- Aromatase Inhibitors: Are There Differences Between Steroidal and Nonsteroidal Aromatase Inhibitors and Do They Matter? (2008) http://theoncologist.alphamedpress.org/content/13/8/829.full

The study focuses on the mechanism of action and effectiveness. It doesn't discuss side effects.

I thought everyone might also appreciate this article about exercise and AIs:
