Hi dear and thanks for your query.

I understand your concern but don't worry so much because provera use can't cause breast cancer if it is used for a short period of time.
According to a new study, it has a very scary side effect: doubling risk of breast cancer,only if it is used for a long period of time ,over five years.
Hence in my opinion if your og-gyn have suggested you to take Provera ,do not hesitate .
If you are afraid for breast cancer and you have familiar history,have a mammography yearly .

All the best
