Breast Thermoloysis Question

Hello,

I am having thermolysis done on my breast and I have hair all over the breast-fine and thick. Is there such thing as over treating the breast area or risk of causing anything more sinister in this area? I have six sessions over the last 2 weeks on one breast (I have very large breasts), each session covering a small patch area to get all the fine hairs and I am wondering if this is too much?
