worried

hello everyone, im not really sure what im after. advice.. support...guidance.....

im a carer for my pop and has had to have a test done that was orginally thought a thyroid problem as hes had those in the past but since then have discovered a lump on his pancreas so hes jsut had one of those ct things where the dyes injected and now just awaiting results. and then he went to the drs today and now they want to do a lung biopsy. hes not too worried about it but im doing enough worrying for both of us and more.
