No Chemo...how wonderful for you.
I wouldnt worry about getting the cream now..... when I had my Radiation I had meetyings with nurses throughout to check on how things were. They will guide you along the way & more than likely supply you with things you may need. Make a note to ask when you first go.
Each Oncologist have their own routines of the treatment they provide. Though I live in a rural area all my surgery & chemo was done in Melbourne. (My radiation was arranged locally for me,, which was great as I would have had to move down to Melb otherwise for the 6 weeks) I had 8 rounds of chemo but other women I have spoken to in my support group only had 6 rounds. I researched my Oncologist & was very impressed with his credentials, so found comfortable in his advice/decisions.
If your Oncologist says your treatment can wait until your return & you are comfortable with that I see no reason why you shouldnt continue with your plans. If you feel time is of the essence maybe you should talk further with him/her telling them of your concerns.
Good luck Hun
