My husband was diagnosed Gleason 9 tb3.He has had HDR Brachytherapy, five weeks of RT followed by three years of HT. The HT was hard , but, he kept going, lack of energy, no libido. He’s been off the HT for over a year now, his PSA is currently 0.2 his strength is returning and his libido has returned. While on his treatment we kept our organic veggie smallholding going, had an extension built (that was hard going) yes, it was hard, yes, he suffered side effects. Mentally it was a challenge for both of us,David had down times, we had tears. But he’s doing well, we are healthy reasonably fit and happily living a good life.
Get the tool kit, do some reading, talk to each other and hang on to the reality that treatments are changing all the time.
He’s now 69, sings and plays ( pro musician)gardens, we have a acre of garden, have a good social life, he also goes sea fishing with his mate, they are like ‘ Last of the summer wine”
The shock of diagnosis is hard, to absorb, life changes, readjustments are inevitable.
