Cancer that originates in a woman's reproductive organs is referred to as gynecologic cancer. Cancer is always named after the body part where it first appears. Gynecologic cancers can start anywhere in a woman's pelvis, which is the area beneath the stomach and between hip bones. Cervical, ovarian, uterine, vaginal, and vulvar cancers are several types of gynecologic cancer. Ovarian cancer is the most common gynecologic cancer.

Dermal fillers based on hyaluronic acid, also known as hyaluronan, are made from a clear material produced naturally in the human body. Hyaluronic acid is a form of sugar (polysaccharide) found in bodily tissues like skin and cartilage. When in gel form, it can react with water and swell, giving it a smoothing/filling effect. Bacteria or rooster combs are two sources of hyaluronic acid utilized in dermal fillers (avian). Hyaluronic acid used in dermal fillers is sometimes chemically changed (crosslinked) to extend its life in the body.
