Young patients with breast cancer

Abstract

Among women diagnosed with early breast cancer, one in four will be premenopausal. In relation to breast cancer, the term “young” typically refers to patients aged less than 40 years. While breast cancer in young women is not common, breast cancer remains the leading cause of cancer deaths among young women. Only about 1 in 40 women diagnosed with breast cancer will be very young (defined here as <35 years).
