What should I do if my family Doctor touched me in and inappropriate manner during a visit?

I went to my family doctor to have him check my lungs. I am sick. He commented on how much I lost in weight. And we discussed my over all symptoms. He sat me on the exam table and sat next to me to listen to my lungs. He lifted my hoodie up over my chest and back to listen to my lungs. He told me he was concerned that I had pneumonia in my upper left lobe and possibly my upper right. Then he reached over and grabbed my left breast and said, " well it does not look like you lost any weight here"? And jiggled it for a second then he let go. I jumped up and pulled my top down and sat in the chair. I was mortified. Why??? I don't know what to do. I have been molested when I was a child. I had come to terms with that. Now this??? What should I do??? Thanks~
