About half of men over the age of 50 are affected by

A) benign prostatic hyperplasia.
B) prostate cancer.
C) cervical cancer.
D) intimal hyperplasia.

Benign prostatic hyperplasia (BPH) is a common condition affecting the prostate gland, which is located beneath the bladder and surrounds the urethra in men. BPH causes enlargement of the prostate gland, leading to urinary symptoms such as weak stream and frequent urination, particularly at night. BPH affects about half of men over the age of 50, making it a commonly encountered condition in primary care. Prostate cancer is also a common condition affecting men, but it is less prevalent than BPH and affects a smaller proportion of men over 50. Cervical cancer and intimal hyperplasia are not related to the male prostate gland and are therefore not correct choices.
