Syphilis (pronounced siff-eh-lis) is a bacterial infection that is sexually transmitted. It progresses in distinct stages. The disease is curable and progression is preventable if syphilis is caught early and treated. But if it isn't treated, it can cause serious damage to the cardiovascular system and brain and lead to blindness and nerve problems.
Syphilis is often called "the great imitator," because its signs and symptoms are indistinguishable from those of other diseases.
Acquired immune deficiency syndrome (AIDS): A syndrome -- caused by the human immunodeficiency virus (HIV) -- in which certain cells of the immune system are destroyed making it difficult to fight infections and certain cancers.
Amenorrhea: When a woman does not get her monthly period.

Bartholin's glands: The small, mucus-producing glands on either side of the vaginal opening.
Benign: Not cancer, as in a benign tumor.
Biological therapy: A treatment that uses the body's own immune system to fight cancer.

Bulbourethral glands (Cowper's glands): Pea-sized structures located on the sides of the urethra just below a man's prostate gland. These glands produce a clear, slippery fluid that empties directly into the urethra. This fluid serves to lubricate the urethra and to neutralize any acidity that may be present due to residual drops of urine in the urethra.
