I am 67. I had T/T for Papillary Cancer followed by RAI. Last week I got my blood results where the Tg. level was 13.6 and my TSH was 0.05(It is 5 months since my very lst.Rai after T/T).
I have 2 opinions expressed: 1) The Oncologist says that my Tg. level is high and that it should be ZERO as I do not have the Thyroid anymore. He has asked me to do a PET SCAN followed by another higher dosage of RAI (150mCi), the previous was 100.
The Endocrinologist says that I should give anotgher 6 months and then have a retest of the Tg.Level in the same Lab. If it goes down, well and good, just follow up for trdeatment. If the Tg. level is on the increase, to do the PET SCAN and other realated treatment. In the meantime he told me to carry on taking my Thyroxine(15mcg) to kdeep the TSH suppressed as above.
Could please advice me which of the 2 should is more favourable.
thank you. - Mahendra
