Breast Health

Early cancer detection requires the latest technology and a collaborative approach.

Mammography still the key to early detection

Mammography has been shown to have a significant impact on the early detection of breast cancer. The earlier breast cancer is found, the better the chances that treatment will work. Advances in digital imaging technology have led to even greater detection rates, particularly in women with dense breasts where traditional 2D mammography imaging may be inconclusive.
