About BIGOSA
The Breast Interest Group of Southern Africa (BIGOSA) is advancing multi- disciplinary breast healthcare across Southern Africa.
Founded in 2011, BIGOSA is a multidisciplinary professional society dedicated to improving the quality of breast healthcare across the region. We bring together healthcare professionals involved in the diagnosis, treatment and management of breast disease, creating a shared platform for education, scientific exchange, collaboration and professional leadership. Our members include surgeons, radiologists, pathologists, oncologists, breast care nurses and allied healthcare professionals working across both the public and private sectors.
Why BIGOSA exists
Breast healthcare is inherently multidisciplinary.
Every patient benefits when healthcare professionals work together, share expertise and deliver coordinated care based on evidence and recognised standards.
While individual disciplines have long been represented through specialist societies, there has historically been no single organisation bringing the entire breast healthcare community together across Southern Africa.
BIGOSA was established to help bridge that gap.
By creating opportunities for collaboration, education and professional leadership, the organisation supports a more connected breast healthcare community and contributes to improving standards of care throughout the region.
Our purpose
To improve the quality of breast healthcare caross Southern Africa through education, multidisciplinary collaboration, scientific exchange and professional leadership.
Our vision
