Hi , my uncle is 60 years old , by sonography it is figured out that prostatectomy grade 2 is enlarged in size 49 cc with heterogeneous with echo texture & irregular margins .psa>100 , right renal cortical cyst, adv-psa ... urologist told us to go for biopsy as there are chances for cancer ..So what should be the next step as biopsy is dangerous , is there any alternative or should we go for it ..All other tests are negative like blood sugar etc , creatinine etc
