Laila374

Hi everyone, 

 after ups And downs , this month PSA came at 4,5 it 's a jump from 1,69 in 3 months, he repeated ct scan and MRT that still showed the spot at the lower of the spine.
His oncologist decided that it's time to start the treatment which is :

chemo with docetaxel. 
Zometa for 12 months

Is there anything else that should be done?
Any advice please? 
Thank you
