Mammograms and ultrasounds are both valuable breast imaging tools, each serving a different purpose. Mammograms use low-dose X-rays to detect microcalcifications and deep-tissue changes that might not be felt physically. They’re recommended yearly for women over 40 and earlier for those with strong family history or high risk.

Ultrasound is more commonly used in younger women with dense breasts. It provides a clearer look at lumps, helping differentiate between solid and fluid-filled structures. Doctors often use both tests together for the most accurate results. Your choice depends on age, symptoms, breast density, and medical history — and your doctor will guide you to the best option.
