Yes they do...that's how they knew he had a growth and took it out. This is bad news but it's not the end of the road for him, not by a long shot and I'm sure Tony and his wife aren't busy picking out a suit to bury him in.
I heard Tony on Sean's show last week and he knew then that there was a good chance that the growth would be a met and he felt good that they found it early when they could deal with it.
I'm praying for strength for him and his family, and for comfort and healing.
Wait. I thought cancer showed up in the blood. Why was the growth allowed to grow at all when they could of seen in his blood that he had cancer cells??
