There is no evidence to support the use of radiotherapy in reducing the risk of in situ carcinoma or the development of invasive breast cancer, following a diagnosis of classic LCIS or any of the newly described LCIS subtypes. However, adjuvant radiotherapy after breast conservation surgery may be considered for women with PLCIS, given the histomorphological similarities with DCIS.
Cancer Australia was established by the Australian Government in 2006 to benefit all Australians affected by cancer, and their families and carers. Cancer Australia aims to reduce the impact of cancer, address disparities and improve outcomes for people affected by cancer by leading and coordinating national, evidence-based interventions across the continuum of care.
