Prostate Health Index (PHI) results: Time for a second opinion?

My husband recently had his first PSA test. It came back at 16.01. He was referred to an NP in urology. She did a DRE, which confirmed an enlarged prostate. She ordered additional PSA testing. The next day, his PHI showed 89.2, PSA total was down to 10.56, PSA free was 1.56, and %Free PSA was 14.8, p2PSA is 42.8

The NP sent a message in my chart stating that there is a 50 possibility of prostate cancer. He has an appointment for an MRI end of June. We are unavailable between May 27 and June 17, and no earlier MRI appointment is available. The NP made a video visit appointment for end of August to discuss MRI results and next steps.
After reading about the PHI tests, and my husband’s results, it seems like there is a greater likelihood of prostate cancer than 50%. My husband has CLL, and has had several secondary cancers. Numerous squamous cell carcinomas, and a malignant gist in his duodenum. Would it be prudent to get a second opinion with a urologist? We were not given the option of seeing a urologist at his first appointment. We know that prostate cancer is slow growing, but still want to speak with a urologist before end of June. Any recommendations?
