My Son Is 46. & Has Had Trouble With His

My son is 46. & has had trouble with his legs itching. No sign of a rash. He decided to see a Dr. who asked him what he thought about it. He answered, Cancer? Last year his wife, was diagnosed with breast cancer. It was such a shock. So, I think he thinks about that. Anyway, the Dr. ordered a blood test, & told my son a Pancreatic enzyme was elevated. Tomorrow, he is having a CT Scan.
I am so fearful & I detect he is as well.
