Hi. Dad has had phlegm on chest for months. Had xrays and antibiotics but confirmed not infection. Been told that nodules look suspicious but not to worry as not very common to go to lungs. Gp said different. His psa dropped from 102 to 17 to 13. Mets in most bones and Gleeson 9. Been told c.t scan to be done. What's your honest thoughts. I'm wanting to be prepared as just 2 off us x
