Limited evidence is available to determine the most appropriate management of women with LCIS. The diagnosis and management of women with LCIS should involve a multidisciplinary team who consider all relevant pathological, radiological and clinical information, and the individual patient’s risk profile and preferences.
Patient involvement is a key principle of multidisciplinary care, and health professionals must ensure that women diagnosed with LCIS receive adequate information. This should include an explanation of the implications of the diagnosis in terms of risk of subsequent invasive breast cancer, and the options regarding surgical management, risk-reducing strategies and surveillance. Patients should be encouraged to be involved in the development of their individual treatment and care plan.
