prostate cancer can be diagnosed by ___________.
testing of prostate specific antigen
semen analysis
biopsy
digital rectal exam

Explanation:

PSA testing screens for elevated antigen levels, semen analysis looks at sperm - related factors, biopsy confirms cancer cells, and digital rectal exam checks for physical changes. Each method has its role in prostate cancer diagnosis.

Answer:

All of the above. Testing of prostate - specific antigen (PSA) can detect elevated levels which may indicate prostate cancer. Semen analysis can sometimes show abnormal findings related to prostate health. Biopsy is the definitive diagnostic method to confirm the presence of cancer cells. Digital rectal exam can help detect any abnormal lumps or changes in the prostate.
