question: Hello doctor, This query is regarding my father. He is 65 years old. He suffers from BPH from the last five years and takes Alfusin-D for the same. Five years back, when he was diagnosed, his PSA was 2.8 ng. Last year, we repeated his test and the PSA was 0.9 ng/ml with normal DRE. An ultrasound of his abdomen and pelvis showed a third-degree prostatomegaly. He does not have any obstructive symptoms other than getting up in the night to urinate. His uroflowmetry also showed normal urine flow. My query is, when should he do his next screening for PSA and DRE, the last one being eight months back. Also, should he go for a surgery? Will the surgery provide any protection against prostate cancer?
