Newly diagnosed but been there before with my 1st husband!

It is so uplifting to find a place to talk to people who know what you are going through. I was diagnosed after a routine mammogram the end of July. I had surgery (double mastectomy) on August 11. My invasive ductal carcinoma was Stage 2 (2 nosed involved) Grade 1, ER/PR+. The initial diagnosis caught me completely offguard to say the least. Just hearing the words "cancer" was enough to make me choke. I had been down this road 10 years ago with the first husband and was left a widow with 3 small children. I never imagined that I would be putting my children through this again. I am having a very hard time putting what I went through with him out of my mind (treatment, outcome, etc.)and focussing on the positive. I was told that I have a good prognosis. Then I met with the oncologist and he ordered an MRI of my liver because I had had a ct and bone scan in early August and the ct scan showed 2 cysts in my liver. I really hadn't thought or worried tto much about the cysts until he ordered this MRI "because the radiologist couldn't see them clearly on the CT so he couldn't be 100% sure they were cysts." Now all I have been able to think about is if they aren't cysts, then they are cancer and that just sent me from Stage 2 to Stage 4 instantly. My MRI is tonight and I'm sure I won't know anything until maybe tomorrow so once again I wait and worry. I am having a port put in next Tuesday followed by chemo (Taxol/Cytoxan once every 3 weeks for 4 sessions). Am just trying to come to grips with one thing at a time and it seems that new little things keep creeping in sending me back to my negative thinking. I guess I just need lots of prayers that they are just cysts and then I can focus on dealing with the chemo and recovery. My emotions are definitely a rollercoaster and sometimes I wonder how I could have been so strong for my husband's cancer and now am falling apart over mine!
