Lung cancer or lymphoma

Hi just for some advice I had a pet scan when I went abroad due to falling ill, I came back home and the gp did an urgent referral. Hospital did everything very quickly, I saw the consultant had a scan and a biopsy last week and was told I would be seen in clinic the following week, with my results. I rang the hospital and was told I would hear something by this evening , no call  the waiting is horrible. Can someone advise. 

Would they only call if the biopsy confirmed cancer. My scans showed enlarged lymph nodes in the neck and chest. I had an ebus biopsy which I was told the results take only a few days .  Thanks Alayna
