My experience with progesterone and question please

Hi, I started to use progesterone cream (natpro) because I have a lot of facial hair... since using it there has been a noticeable improvement... is this one of the benifits of using the cream..? But I also got sores at the side of my mouth which cracked and has taken days to clear up and has left the side of my mouth still red but not sore...
I eat very healthy with lots of fruit and nuts as I don't eat meat or chicken just fish once a week... I take a multi vit, flax seed oil, calcium tabs, cranberry for cystites - which has helped a lot and folic acid tabs...
I had breast cancer in '99 will the cream help against it's return...? I've been tested and I do have the gene...!!
I'm 68 years old and I'm thrilled at the fact that the facial hair has just about gone but I'm concerned about the side effects I've been reading about on the net

I would appreciate your comments...

Kind regard Maureem
