Breast cancer awareness is rising among the younger generation, yet confusion persists regarding the difference between Breast Ultrasound (USG) and Mammography. While both aim to detect breast abnormalities, they operate on different principles and serve different purposes.

Breast Ultrasound uses ultrasonic sound waves to visualize internal tissue. This method is highly effective for examining lumps or cysts felt during a physical exam. It is typically recommended for younger women or those with dense breast tissue. Since it uses no radiation, it is safe to perform at any time.

In contrast, Mammography utilizes low-dose X-rays, compressing the breast between two plates to capture detailed images. It serves as the gold standard for routine screening in women over 40, capable of detecting micro-calcifications or tiny abnormalities invisible to the naked eye.

Preparation and Samples: Neither test requires blood or urine samples; they are non-invasive imaging procedures. However, timing is everything for Mammography.

It is strongly advised to schedule a Mammography on days 10 to 12, counted from the first day of menstruation. During this window, breast density and sensitivity are lower, making the procedure more comfortable and the results more accurate. For post-menopausal women, Mammography can be performed at any time.

Understanding these differences ensures that early detection efforts are effective and appropriate. Always consult a healthcare provider to determine which screening method aligns best with age and medical history.
