Ca 125 test: 概述 CA 125 检测可测量出血液中癌抗原

概述 CA 125 检测可测量出血液中癌抗原 125 蛋白的含量。癌抗原 125 也称为 CA 125。 可能在治疗期间和治疗后使用此检测来监测某些癌症。在某些情况下，这项检测可用于发现存在极高卵巢癌风险的人群的早期卵巢癌体征。 由于许多状况可能会导致这种蛋白的水平升高，因此 CA 125 检测通常不足以准确筛查卵巢癌。 可能会导致 CA 125 水平升高的状况包括许多非癌性状况，例如 ... A CA 125 test isn't accurate enough to use for ovarian cancer screening in general because many conditions can increase the level of this protein. Conditions that can cause an increase in CA 125 include many that aren't cancerous, such as menstruation and uterine fibroids. Certain cancers may also cause an increased level of CA 125 , including ovarian, endometrial, peritoneal and fallopian tube cancers. If your cyst appears solid and you're at high risk of ovarian cancer, your provider might order a cancer antigen 125 ( CA 125 ) test or other blood tests. CA 125 levels can also be elevated in noncancerous conditions, such as endometriosis and pelvic inflammatory disease. Ovarian cancer is a growth of cells that forms in the ovaries. The cells multiply quickly and can invade and destroy healthy body tissue. The female reproductive system contains two ovaries, one on each side of the uterus. The ovaries — each about the size of an almond — produce eggs (ova) as well as the hormones estrogen and progesterone.
