Hi JujiLow,
I'm a newly diagnosed OC patient with a T4 tumour in my tongue. I'm also in the UK (within the M25) and also a young patient (39) with a similar history to you (light smoker, even lighter drinker, female)

I've only just started my treatment and am on 2 doses of immunotherapy before I head off to have surgery at the end of August where up to 2/3rds of my tongue will be removed and replaced with a free flap, not sure where they're planning to take it from yet but I'm liking it from my leg if I get to chose.

Anyway hello here, sorry to meet you in such cruddy circumstances.
