When should i get my first breast ultrasound? what age is appropriate?

Breast ultrasound: Diagnostic ultrasound (US) is performed to evaluate a specific breast symptom (e.g., lump) and may be performed at any age. Screening US is performed to detect cancer in women with no breast symptoms, and should be performed in combination with annual mammograms (MG) beginning at age 40. MG still remains very important for detection of some small breast cancers that can easily be missed by US.
