Final answer:
Benign prostatic hyperplasia (BPH) signifies an enlarged prostate, a condition different from prostate cancer, characterized by non-cancerous enlargement of the prostate gland causing symptoms like urination difficulties.
Step-by-step explanation:
Benign prostatic hyperplasia (BPH) is another term for b) enlarged prostate. BPH is a non-cancerous increase in size of the prostate gland which can cause constriction of the urethra, leading to symptoms such as a frequent urge to urinate and a weak urine stream. Unlike prostate cancer, BPH does not involve the metastasis of cancer cells. Treatments for BPH range from medication for mild to moderate symptoms to surgery for severe cases where part of the prostate tissue is removed. It's important to distinguish BPH from prostate cancer, which is detected through a blood test, a rectal exam, and if necessary, confirmed by biopsy of the cells.
