Definition and description of Ovarian Cancer

<div dir="ltr" style="text-align: left;" trbidi="on"><div style="text-align: justify;"><span style="font-size: large;">Definition</span></div><div style="text-align: justify;"><br /> </div><div style="text-align: justify;">Ovarian cancer is cancer of the ovaries, the egg-releasing and hormone-producing organs of the female reproductive tract. Cancerous, or malignant, cells divide and multiply in an abnormal fashion.</div><div style="text-align: justify;"><br /> </div><div style="text-align: justify;">Ovarian cancer is cancer that develops in one or both ovaries--glands in females where reproductive eggs are made. Typically, the cancer forms on the ovary's surface. Although many cases of ovarian cancer aren't caught until the cancer has metastasized, or spread, outside of the ovaries, improvements in treatment and diagnosis have increased survival rates.</div><div style="text-align: justify;"><br /> </div><div style="text-align: justify;"><span style="font-size: large;">Description</span></div><div style="text-align: justify;"><br /> </div><div style="text-align: justify;">Ovarian cancer is a malignant tumor of the ovary, the egg sac in a female. Women who have a family history of ovarian cancer are at an increased risk of developing ovarian cancer. Hereditary ovarian cancer makes up a small percentage of all cases of ovarian cancer. Three hereditary patterns have been identified: ovarian cancer alone, ovarian and breast cancers, and ovarian and colon cancers. Ovarian cancer is difficult to detect early because there usually are no symptoms and the symptoms that do occur tend to be vague. Detection involves physical examination (including pelvic exam), ultrasound, X-ray tests, CA 125 test, and biopsy of the ovary. Most ovarian growths in women under age 30 are benign (noncancerous), fluid-filled cysts.</div><div style="text-align: justify;"><br /> </div><div style="text-align: justify;">The ovaries are small, almond-shaped organs, located in the pelvic region, one on either side of the uterus. When a woman is in her childbearing years, the ovaries alternate to produce and release an egg each month during the menstrual cycle. The released egg is picked up by the adjacent fallopian tube, and continues down toward the uterus. The ovaries also produce and secrete the female hormones estrogen and progesterone, which regulate the menstrual cycle and pregnancy, as well as support the development of the secondary female sexual characteristics (breasts, body shape, and body hair). During pregnancy and when women take certain medications, such as oral contraceptives, the ovaries are given a rest from their usual monthly duties.</div><div style="text-align: justify;"><br /> </div><div style="text-align: justify;">Most (more than 90%) ovarian cancers are classified as "epithelial" and are believed to arise from the surface (epithelium) of the ovary. However, some evidence suggests that the fallopian tube could also be the source of some ovarian cancers. Since the ovaries and tubes are closely related to each other, it is thought that these fallopian cancer cells can mimic ovarian cancer. Other types may arise from the egg cells (germ cell tumor) or supporting cells. These cancers are grouped into the category of gynecologic cancer.</div></div>
