I just found out my dad had prostate cancer?

I just found out today. My dad waited to tell my sister and I I knew he had surgery, but I didn’t know it was this serious and my emotions right now. He did get surgery and they got everything out but he has to get checkups for the next year to make sure it doesn’t come back. My question is how do I get through this?
