Ratings for Dr. Leonard M. Klein
If you have Estrogen positive breast cancer that returns after initial treatment, be sure to request that Dr. Klein tests you for HER-2 cancer. This was never tested by Dr. Klein. It was discovered through a second opinion at Cancer Centers of America, but unfortunately it was too late for my Mother. Dr. Klein prescribed Afinitor which is not the proper treatment for HER-2 and it had devastating dehydration side effects from diarrhea which is believed to lead to her early passing.
