hi Mg2 I had lumpectomy 14 December my radiotherapy starting 27 Jan. Similar to you. I live remotely 500km from treatment so had all appointments at once last week & have already had the Tatt markers also was told about the plastic shield (metaphil ? Couldn’t remember the name) they put a sample on my inner wrist as a test to ensure no reaction to it. So plan to have that.
Hope yours all goes well. Thanks for the rad tips everyone. xx
