The only additional comment I would add (as me and my brother discussed issues very similar to this )
ie My brother had TURP - yet nothing sinister found. Subsequent mpMRI indicated potential lesion
Have you asked what detail of scan has actually confirmed the cancerous lesion(s) in what is now left of your prostate
Do you know what % of prostate was actually removed ?
Their position and size ? Had TURP actually removed part of a larger lesion ?
PSA may be a double edged sword, maybe Lyn can explain better than me. A value at or near 0.8 in Nov. could be masking a problem ?
ie Grade 4 cancer has been present in your prostate, ie intermediate risk. Not a low risk., so in theory this has 100% been removed by the TURP. However your consultant indicates cancer is present ? Do you talk through this in detail ?
(I agree you should have a new baseline now) - will further scans be done in November, or a biospy then ? or is next decision solely made on PSA value ?
Has TURP affected bladder 'end' to possibly negate option on RP in future ? (this was not the sole reason my brother choose RT, by the way)
