Blood Androgen Levels

Androgens (such as testosterone) are natural hormones. They are important in sexual development in both men and women.

In women, small amounts of androgens are produced by the ovaries and the adrenal glands.

Higher levels of androgens in the blood may be linked to an increased risk of breast cancer in women [59-62].

Most studies on androgens and breast cancer risk have looked at the androgen testosterone.
