My father aged 72 has many issues ..
diabetes, parkinsons , bullous pemphigoid , and recently high
thyroid n enlarged prostate grade 2...his total psa is 2450 and free psa is 250 ...he's on cathether from last month ...he's almost bedridden...should we go for biopsy or are there any less invasive tests to detect cancer because hes too weak...does a psa above 2000 mean advanced cancer ?
