I have a haematology appointment tomorrow. I had a CT scan 2 weeks ago and they found enlarged lymph nodes in my chest. Dr said it could be either sarcoidosis or lymphoma. 

i’m just wondering what bloods etc they will take? Have a respiratory appointment next week which for some reason I feel more nervous about. 

I also have a lump on my breast so been referred to breast cancer clinic. I assume I should mention this at both appointments too? 

Thank you.
