My Diagnostic Mammogram

I had a diagnostic mammogram today. Actually, she took several views saying her job was to make the 'spot' disappear. It didn't disappear. It's a small spot, round like a pea. I can't feel it yet, although it does hurt a bit, if I press on it long enough. Well, if I press long enough, any place will begin to hurt.
My husband is a family doctor. He came home for lunch today, after calling and not being able to get through to me: I was on the phone with my sister. I was pleased that he came home to check on me. I thought he'd forgotten about my appointment. After lunch, he talked with a General Surgeon at OU to question why it is necessary to have an ultrasound rather than go right to checking the cells to discover if they are cancerous or not. I don't remember exactly why, but the GS said that is the correct next step.
So, the waiting game begins. Next the radiologist checks today's pictures with some taken two years ago, (I missed having a mammogram last year). If it looks suspicious to him, then next will come the ultrasound. I'll hear something back from my doctor's office next week.
This really impacts life. I know I sound like a whinner, but it's hard to concentrate on regular life with something like this hanging 'out there' unsettled.
I hurt for my sister. The doctors knew immediately upon seeing her mammogram that she had cancer. It must have looked quite messy on the screen. Teresa knew she had a rather large lump in her breast for more than a year. She just never went to have it checked out. I also feel responsible for that. Perhaps if I had insisted that she 'go to the doctor now and have it looked at!' then, perhaps she would have done so. Jeff told me that is 'co-dependency' and 'sick.' Well, maybe. Except, that it's always been that way with my sister. Either mom (before she died) or me -since mom died- have had to direct her to do those sorts of things. I feel it's partially my fault that she didn't have it checked out because I didn't sound the alarm. I said things like, 'I had a benign tumor removed years ago' and 'no one in our family had breast cancer.' I was wrong. Our mother's sister had a masectomy in her 40s. We thought her doctor was just 'knife happy' and didn't know what he was doing. She didn't have to have chemo treatments and the cancer never came back. My grandfather's sister died of breast cancer in her 40s or 50s. His paternal grandmother had cancer, listed in the 1880s census report under chronic illness. And there are other's in the family with different types of cancer, mostly colon cancer, I believe.
Teresa had her 3rd chemo treatment this week. So far, she isn't as sick as she was for the last one. Do people survive cancer that moves into the lymp nodes?
I hate cancer. It feels like a personal enemy. This morning as I left the clinic, I remembered what I was doing at this same time 16 years ago: My first child was born in Chicago 16 years ago today. My mom was still alive, Teresa didn't have cancer and I was about to begin breast-feeding for the first time. Those were happier days, obviously.
