My brother-in-law was diagnosed around Christmas with the same type of breast cancer I had. Men develop breast cancer just like women do, it is just not as often. The treatments are the same. My brother-in-law had a mastectomy and it was early stage. He had an oncotype-DX test and it was so low grade, he did not have to have any further treatment. It tested out er/pr positive her2 neg. He felt a lump in his breast and when he pushed on it, fluid seeped out of his nipple. He went right in to have the doctor check it, the doctor sent him in for a mammogram.... surgery. Done... He is doing great.
