Breast Cancer Journey

My medical team plan is for me to have four chemo treatments, wait two weeks for optimal results as far as another blast to those damn cancer cells from chemo #4, then have a PET scan (April 2) which will show where and if the  cancer has spread, or optimally, how much the tumors have shrunk. I have heard that some people's tumors disappeared and they couldn't find them on the scan! I have two titanium markers in my left breast to mark my main tumor, so the location will be pinpointed should it have disappeared. I'm not expecting it to disappear, it was quite large. I still have disfiguration on the breast, you can still tell something is wrong, it's off kilter in size and appearance, but the swelling is way down and that's a good sign.  I wish I had a picture of the first pet scan. The scan of my body was lit up like a Christmas tree. (That's not good. You don't want to be lit, haha.) The tumor filled the whole breast and the one in the axilla (armpit) node...

Things were uneventful after the second chemo except for I hit a roadblock over the weekend, just before my third chemo appointment. Severe fatigue hit me so suddenly, it was alarming. I felt too weak to walk or stand up. I went to bed Saturday night at 6:00 PM, slept till 10:00 PM, got up briefly, went back to bed and slept till 3:00 AM, woke up for a bit, then fell back to sleep at 5:00. That day I felt a little bit better, but the fatigue lasted through the next two days. I've also had a sore throat for two straight weeks. It's not getting any worse, but it's not getting any better. No fever. I'm worried about my white cell count, it could be super low. I have not had this level of fatigue this late in the chemo cycle until this weekend, I was feeling very well. I will find out at my next appointment which is in two days. I'm hoping that it is just my body trying to catch up on sleep, as I have only been able to sleep intermittently each night for about two hours...
