Anyone been diagnosed grade 3 - lymph node - stage 2 BC

Hi there 

Well I have had it confirmed I have grade 3 in my left nymph node and stage 2 breast cancer they’ve said it’s the most common cancer and it’s curable 

i am going for my MRI tomorrow and CT Thursday to see if any spread 

As you can imagine I am beside myself because of the unknown

They want to start chemo then surgery 

Any stories or advice I would really appreciate
