Abstract: Methods and systems for detecting anomaly in at least one body part among a pair of symmetrical body parts (such as breasts) are described. A device can receive first parameters corresponding to signals scattered from a first body part among a pair of symmetrical body parts, and can receive second parameters corresponding to signals scattered from a second body part among the pair of symmetrical body parts. The device can perform a first comparison between the first parameters and the second parameters. The device can perform a second comparison between the first parameters and first historical data, and a third comparison between the second parameters and second historical data. The device can, based on at least one of the first, second, and third comparisons, determine a likelihood of a presence of an anomaly, such as malignant tissue, in at least one of the first and second body parts.
