Unique features of young age breast cancer and its management.

Young age breast cancer (YABC) has unique clinical and biological features that are not seen in older patients. Breast tumor biology is more aggressive and is associated with an unfavorable prognosis in younger women. The diagnosis of breast cancer is often delayed, resulting in their initial presentation with more advanced disease. Together, these characteristics lead to a poorer prognosis in younger women than in older women. Young women who receive breast-conserving therapy have a higher rate of local recurrence. Therefore, it is important to secure sufficient resection margins and consider boost radiotherapy to prevent local treatment failure. Based on age alone, patients with YABC should be regarded as high-risk cases, and they should be treated with adjuvant chemotherapy. Special considerations regarding psychosocial factors and fertility should be taken into account for young patients. This review discusses the major considerations and principles concerning the management of patients with YABC.
