Scared

HI, wondering if I can get any advice. I have rhuematoid arthritis & my spine at the bottom of my back was very bad the gp sent me for an xray long story short they seen something & sent me for an mri they told me my back was fine but they had found clusters of enlarged lymph nodes in my abdomen they refered me for a ct which I got a few days later when I got the ct scan they didn't really tell me much but said the clusters were bigger than they should be and they referred me to heamotology has anyone else went through this process im scared I have lymphoma will they be able to tell me at my heamotology appointment? All my scans etc have been done so quickly its worrying. Thanks in advance for any advice
