Didn't need any certainty, like I said the surgery falls under the breast cancer act of 1998. That law not only applies to women, but also to men. Men also can have breast cancer. Most surgeons/doctors should know of this breast cancer act of 1998. Again, my surgeon sent the sample off for cancer testing, it came back binai. All I had to do was pay $250 deductible if I remember correctly. And I did have blue cross/blue shield insurance at that particular time. If your insurance company gives you trouble, file a claim against them. You will win the case. They can't argue the breast cancer act of 1998, its in black and white. I would wish you good luck, but you won't need it..
