Abstract
Meme kanseri, üreme çağındaki kadınların en sık görülen malignitesidir. Günümüzde meme kanseri erken teşhis edilir ve hastaların sağkalım oranı yüksektir. Bu nedenle hamile kalmak isteyen hastalar çok yaygındır. Bu derlemede doğurganlığın korunması, ovulasyon indüksiyonu ve indikiyonun güvenliği ve gebelik sonuçları tartışılmıştır.

Abstract
Breast cancer is the most common malignancy of women at reproductive age. Nowadays, with increasing early diagnosis, survival rate is higher, which is why the number of patients wanting to get pregnant are on the rise. Fertility preservation, ovulation induction, the safety of these interventions and pregnancy results are discussed in this review.
