What is the normal range for CA 125?

How is CA 125 measured?

CA 125 is usually measured from a blood sample. It can also be measured in fluid from the chest or abdominal cavity. The tests currently in use are all based upon the use of an antibody that is directed against the CA 125 protein (monoclonal antibody technique).
In 1996, an improved version of the test was introduced and is sometimes denoted as CA 125 - II. The numerical figure of the second generation test results may be higher or lower than a first generation test. When comparing multiple test results over time, it can be important to know which method was used.

The normal values for CA 125 may vary slightly among individual laboratories. In most laboratories, the normal value is less than 35 U /ml.

What does an elevated CA 125 mean, and how is the test used?

It is not possible to interpret the meaning of an abnormally high CA 125 without additional information about the particular patient being evaluated. The reason is that blood levels of this protein can be increased in many different benign and malignant conditions. The two most frequent situations in which CA 125 is used is to monitor patients with a known cancer (malignancy) or as one of several tests in the workup of a patient suspected of having a tumor.
The most common use of the test is the monitoring of women with known cancer of the ovary (ovarian cancer). In the patient who is known to have a malignancy, such as ovarian cancer, the CA 125 level can be monitored periodically. A decreasing level generally indicates that therapy, including chemotherapy, has been effective, while an increasing level indicates tumor recurrence. Because of test variation, small changes are usually not considered significant. A doubling or halving of the previous value would be important.
In the patient who is being evaluated for a pelvic mass, a CA 125 level greater than 65 is associated with malignancy in approximately 90% of cases. However, without a demonstrable mass, the association is much weaker.

"Hard nipples" - areola or nipple skin

Someone once wrote"... when i get really cold, or get goosebumbs all over my body, the whole things really scrunch up, like, my entire areola scrunches itself up into a wrinkled little mound. it looks really weird and ugly, and i haven't ever seen other people's breasts do it. what is wrong with my areola/nipples??" The answer: Well nothing is wrong. This is what my areola does too. It's a normal reaction to the coldness or to irritation / stimulation. The little muscles in the areola do a similar goosebump thing as your other skin can do. People often call this phenomenon "hard nipples". Also note that skin on areola has less feeling or sensation to it than other areas of your body. If the areola was very sensitive, then breastfeeding would probably be quite uncomfortable because the baby pulls and tugs it! The nipples are sensitive but the sensitivity changes with hormonal changes, such as occur at mestrual cycle or pregnancy. Also this v...

Kate Jackson Breast Cancer a flash back

THE MOST MOMENTOUS CHANGE IN Kate Jackson's life began early one morning in January 1987, during her fourth season on the hit TV series Scarecrow and Mrs. King. After a phone call informed her that the show's taping was canceled because costar Bruce Boxleitner had the flu, Jackson went back to sleep. When she woke several hours later, "It was out of the blue, but perfectly clear," she recalls. "I sat up in bed and literally said, 'You have to have a mammogram.' " She did, and two days later a biopsy confirmed her vague fears: A minute growth found in her left breast was determined to be malignant. "I was forced to face, squared up, my own mortality," says Jackson. "I had to decide whether I wanted to live or to die. And if you choose life, as I did, it's never the same." For three TV seasons 16 years ago, she was famous as Sabrina Duncan, a girl-next-door gone glamorous and the character critics dubbed the brainiest o...

The four stages of breast development

In Stage 1 shows the flat breasts of childhood. By Stage 2, breast buds are formed as milk ducts and fat tissue develop. In Stage 3, the breast become round and full, and the areola darkens. Stage 4 shows fully mature breasts. (Illustration by GGS Information Services.) period begins. Usually these signs are accompanied by the appearance of pubic hair and hair under the arms. Once ovulation and menstruation begin, the maturing of the breasts begins with the formation of secretory glands at the end of the milk ducts. The breasts and duct system continue to grow and mature with the development of many glands and lobules. The rate at which breasts grow varies significantly and is different for each young woman. Breast development occurs in five stages: Stage One: In preadolescence, the breasts are flat and only the tip of the nipple is raised. Stage Two: Buds appear, breast and nipple are raised, fat tissue begins to form and the areola (dark area of skin that ...
