Hi Sarah
My husband was diagnosed with Advanced PCA after a very very high PSA test in October.
Treatment varies but at our local hospital they follow a protocol of hormone treatment starting as soon as possible and then chemo starting within 12 weeks. It seems that if the cancer has spread to bones the only time that this particular hospital doesn't offer early chemo (after the recent research trial which showed that this could be beneficial) is when the patient is either too weak for the chemo or they have other medical conditions which make it particularly risky.
Even if it is offered, however, it is the patients choice as to whether they go ahead. My husband decided to have it because we have two two teenage sons and he wants to throw everything at it. Other people, for completely valid reasons, have decided that it's not the right thing for them.
(Just for info - in our case we were told that he had PCA which had spread to his bones before he had an MRI or bone scan because the PSA test result was so high. The scans etc were just to confirm locations etc.)
I hope you got useful info today. I found the specialist nurses from this charity really helpful in those first few weeks. Its definitely worth giving them a call if you have any questions x
