Dads cancer again ....

I think my dad has cancer again, but doesn’t want to tell me. Over 10 years ago, my dad fought cancer ! and my family and I were aware that it could come back...and this might be it. He does have symptoms, like he urinates blood(my mom told me) and my mother told me he went to the doctors and they said something was wrong with his prostate, (the doctors need to do more test in order to find out if it’s cancer) I’m just scared that he has cancer again... :( please pray for my dad! It would mean the world to me! thanks
