Ultrasound
A breast ultrasound commonly used to screen for cancers and other breast abnormalities using sound waves to produce pictures of the internal structures of the breast. Unlike X-rays and CT scans, ultrasounds are considered safe for pregnant women.
Breast ultrasound can detect lumps (filled with fluid; cyst or solid) in women with dense breasts, swelling and breast pain. It can also add information to the other tests like mammograms or breast MRI. For women under the age of 30 years, ultrasound alone is sufficient to detect breast cancers and other abnormalities.
