Has anyone had these symptoms & been diagnosed with lymphoma

Hey my name is Cathy I am 29 and i have been having a few symptoms over the last year but recent months it's been worse.

I get night sweats but not every night I did have itching but that's gone down now.

My white blood cell count is low 

My liver function is low

Inflation markers are up too

I have been getting infection after Infection and flu symptoms which are a bit better now

I have pain in my legs and knees and my back and chest

I saw a hematologist recently and he got me to have a ct scan and said that I have something in my chest and its  3.7cm by 8.1cm by 4.7cm.

Having a mri next week of my back.and then seeing hematologist he said I may have to have a biopsy 

 

Do you think this is lymphoma? Has anyone else had these symptoms.
