Management of Early Invasive Breast Cancer in Very Young Women (<35 years)

BackgroundTo give an overview about current treatment recommendations and special problems concerning the management of women <35 years with early breast cancer.MethodsWe performed a selective systematic literature review. We discussed with reference to key studies and meta-analyses, current standards of care, and controversies regarding patient management.ResultsBreast cancer in patients younger than 35 years is rare but associated with an unsatisfactory prognosis. Local treatment should not differ from general guidelines, but awareness of the high risk of local recurrence must be maintained. Adjuvant polychemotherapy is almost always indicated, standard endocrine therapy is tamoxifen. Before the start of systemic therapy, the patient must be offered different types of fertility preservation. Pregnancy related breast cancer is not associated with a worse prognosis, but with delayed diagnosis. Therefore, every suspicious lesion in the breast or axilla must be imaged and biopsied. The optimal time to delay pregnancy following the diagnosis is unknown. Hormonal contraceptives are contraindicated after breast cancer. Every woman <35 years diagnosed with breast cancer should be offered genetic counseling.ConclusionThe management of breast cancer in very young women requires a multidisciplinary team to find the optimal treatment and to solve their specific problems.
