Sorry to hear of your troubles but I too always have to make appt. for my mammograms. Also, I wanted to let you know that I am on the small side as far as breast size goes and the test is relatively painless. They do have to squeeze as much tissue into the clampy thing as possible to get the biggest area possible covered but it is not painful just uncomfortable. They do stick little circle things on the nipples so the radiologist can distinguish them.
When my lumps were found from a self-exam the next step was a mammogram but after they showed up on the mammogram, I was sent for an ultra-sound of the breast. So don't be surprised if that may be suggested as the next step.
I'm sure that most men wouldn't have known to make an appt ahead of time for this procedure. Try to keep calm and let us know how it goes on the 23rd.
