Breast radial scars, also known as complex sclerosing lesions, are benign (non-cancerous) breast abnormalities which received this name due to their star-shaped scar-like appearance (they are not associated with scars related to surgery or trauma). These lesions are made up of fibrous and glandular tissue and can be detected during breast imaging, such as mammography or ultrasound.
While radial scars themselves are not cancerous, they are considered “high-risk” lesions because they are associated with a small increased risk of breast cancer. They can also mimic the appearance of breast cancer on imaging, leading to the need for further evaluation and occasionally needle biopsy to confirm the diagnosis.
Treatment options can include surgical removal of the radial scar or close monitoring, depending on the individual’s specific circumstances and risk factors.
Management of radial scars is best determined in consultation with a breast surgeon who can help you understand your options and the risks and benefits of each approach.
