Worried sick

Hi all, this is my first post and my head is spinning so please be gentle. 

I am 49f and generally in good health. For info, I had my left kidney removed around 20 years ago. I have had episodes of severe epigastric pain for several months that would last anywhere from an hour to 6 hours, and slight pain and tenderness in my upper.left abdomen. I would be ready to visit a&e and the pain would subside, so.i decided to try my GP. After a battle to get an appointment, I saw a dr who suspected gallstones and referred me for an urgent ultrasound. That was last Tues, after a 6 day wait. I had the ultrasound and that evening I had 3 missed calls from my surgery whilst I was working. On the 4th call I answered and it was the surgery, saying the dr wanted to see me the next day. At the appointment, he - very matter of factly - told me there were two lesions in the left lobe of my liver that required an urgent referral to hepatology as there was suspected malignancy. I explained i am due to go abroad next Thurs dor a week and he asked if I could cancel. He didn't seem to want to explain or reassure and everything I know ive found out from the notes on the NHS app. 

The lesion of concern is 'a 46x35x39mm heterogeneous focal solid lesion within the left lobe with a halo appearance noted. Minimal internal vascularity seen. Ultrasound appearances are suspicious hepatic malignancy'. The smaller lesion is a 27x22x22mm avascular well circumscribed hyperechoic focal lesion seen within the right lobe.

I was referred to hepatology Thurs morning and the referral was reviewed yesterday evening. The notes say "A specialist at Urgent Suspected Cancer Gastroenterology has reviewed your referral and advised the referrer to consider a different course of action. **** medical practice will be in touch to explain what to do next".

My anxiety is through the roof and, of course, it's a bank Holiday so I have to wait until Tues to find out what this means. I know it's impossible for anyone to be able to tell me whether this is a good thing and that I just have to try and think positive until I know for sure, but that is much easier said than done! I guess I just wanted to hear if anyone else had experienced something similar, or could perhaps reassure me that this means it's not urgent after all.

Yesterday was the anniversary of my family losing my sister to cancer and the thought of having to tell my parents that I have it too is something that is keeping me awake at night.
