forgot to mention other yeast killers for growths under woman's breasts:

-tea tree oil
-OTC athlete's foot remedies such as the lotrimin, but there are others that
come in other forms such as powder she might like better.

While working as RN in the hospital, I have treated growths under breasts, I
don't remember what it was or the medication used (it has been a while, but
remember doing it) I put some cream on the area (underneath large, pendulous
breasts) then put folded up wash cloths underneath. This particular lady's
breasts were heavy enough and hung down low enough to pin those cloths in
there nicely.  Just my experience.

Procedure:

cleanse area gently with warm water, mild mild soap if any, rinse well, pat
dry, apply cream or powder , place soft, absorbant material and hope it
stays until next time.  If it gets damp and sweaty, replace it with more
clean and dry material.  THis was done probably twice a day, morning and
just before bedtime, not including towel changes if needed.
