Lumpectomy, radiation and now liver cyst

I am struggling this evening as I have just had a call from the hospital. I am into day 3 of radiation after a lumpectomy and the hospital just called to answer one of my questions from radiation but also said they saw a liver cyst on the scan this morning. Nothing to worry about ! and we will tell you more if we know anything else on Monday when you come for your radiation otherwise will see you Tuesday after the final radiation.  Not sure what to do all weekend now as I am thinking the worse. Anyone else had similar. Thanks.
