Yes, Ehlers-Danlos Syndrome (EDS) can affect the breasts. As a connective tissue disorder, EDS impacts the structural integrity of various tissues throughout the body, including those that make up the breasts. To better understand how EDS can affect the breasts, it’s helpful to first examine the basic anatomy of the breast and how connective tissue plays a key role in its structure and function.
Anatomy and Physiology of the Breast
The breast is a complex organ designed primarily for lactation. It is composed of:
Surrounding these structures is a thin layer of connective tissue called fascia, which encircles the breast and anchors it to the underlying pectoralis muscle. This connective tissue framework is essential for maintaining the breast’s position and structure. The skin covering the breast, like skin elsewhere, is supported by collagen and elastin, both of which depend on healthy connective tissue to maintain elasticity and resilience.

EDS, as a disorder of connective tissue, can disrupt the structural integrity of the fascia, skin, and supporting tissues in the breast. This can result in:
Because the breast relies heavily on connective tissue for its structure, collagen dysfunction in EDS can lead to a variety of issues:
EDS can indeed affect the breasts due to its impact on connective tissue, which plays a critical role in the breast’s structure and support. Symptoms can vary widely depending on the type of EDS, ranging from stretch marks and pain to changes in chest shape or skin texture. Understanding how your specific type of EDS relates to these symptoms can help guide appropriate care and management strategies.
Hypermobile EDS (hEDS): Patients with hEDS may develop unexplained stretch marks on the breasts, groin, thighs, or abdomen. This symptom is listed as a major diagnostic criterion and is often noticed in adolescents or prepubertal individuals, regardless of significant weight changes.
Vascular EDS (vEDS): Vascular EDS can cause thin, translucent skin, which can be particularly noticeable on the chest and abdomen. The fragile skin may make the breasts more prone to bruising or injury.
Cardiac-Valvular EDS (cvEDS): Some patients with this subtype may experience pectus deformities, such as pectus excavatum (sunken chest). This can alter the structural foundation of the breast tissue, potentially affecting its appearance or function.
Musculocontractural EDS (mcEDS): Patients with mcEDS may develop chest deformities, such as a flattened or sunken chest, which can directly impact the breast’s shape and overall support.
