Thanks for your question on Chat Doctor. Normal PSA level is less than 4. So you are having higher levels. In old age (more than 60 years) causes for higher PSA level are1. Benign Prostatic Hypertrophy (BPH)2. Prostatic cancer3. Prostate infection. So better to consult neurosurgeon and get done clinical examination and transrectal ultrasound.  If needed transrectal biopsy of prostate is also needed.
