Who Gets Thyroid & Breast Nodules and What Are the Risk Factors?
Why Do Women Get Thyroid and Breast Nodules?
The main factor contributing to higher incidences of thyroid and breast nodules in women is the hormonal effect, especially estrogen. Estrogen is crucial to the growth and development of female reproductive tissues. But it may also activate the development of other hormonally sensitive tissues, such as those of the thyroid and breasts, making the formation of a nodule more probable.
