Hi there.

It is perfectly understandable that you are worried about your situation. I have just finished treatment for diffuse large B cell non Hodgkin lymphoma. I didn't have any lumps in the beginning, just the night sweats, itchy skin and some kidney discomfort. I can't tell you that it will be all right, but I can say that particular cancer is very treatable. I was late to diagnosis because being a guy, I ignored the symptoms of being sick, and just took some pain killers for a few weeks. It was a blood test by my GP that highlighted my problem while looking at a potential kidney stone problem. 
I had a pet Ct scan, but I also had a biopsy which took a while to come back, however the hospital doctors already had suggested to me what I had.
From the mention of cancer, I started to fall apart, but was reassured very early on that it was treatable.

Personally, I struggled to except the concept of my disease but with the help of the medical staff I overcame the initial understanding of what was wrong and how they could fix it.

It is a very frightening journey and I won't explain my treatment, as there are 60 different types of lymphoma apparently. It is easy for me to say but Tuesday isn't too far away, so don't be consumed by fear, and have faith in your medical staff.

I guess this'll may be little or no use or help at all, but it was difficult for me, as I didn't ask any questions because I was too frightened of the possible answers. I could feel your worry by reading your post and just wanted to at least give you one prospective. Try and be strong and stay positive, as lymphoma is very treatable. I've added a link below to what I have, but please wait for a correct diagnosis as I managed to miss lead myself in the beginning by jumping the gun.
