Kathy,

Herceptin won't affect your PET scan. The only factors to be concerned about are that you make sure you fasted for at least 6 hours, don't exercise for 24 hours, and stay warm (just don't get chilled)

My diagnosis is very similar to yours. I had PET scans at the beginning and then when I finished treatment. I worked in a PET/CT department and was very paranoid about recurrence since I saw it every day. I took a different job and over the last few years have been able to see cancer in the rearview mirror as my fears receded and my life came back into focus. Be patient with yourself- it takes a while for all the symptoms to subside after all you had done. And treat yourself well

All the best,

Henny
