Limited evidence exists on the use of contraceptive methods among breast cancer survivors. Lambertini and colleagues 1 report on the use of contraception among premenopausal women with early-stage breast cancer who participated in the multicenter Cancer Toxicity (CANTO) cohort study, finding that at the time of diagnosis, 54.2% of patients reported contraceptive use, with most women choosing hormonal methods. After diagnosis and during follow-up, the use of contraception decreased significantly to approximately 40% (38.9% at year 1 and 41.2% at year 2), and most patients reported using reversible mechanical methods. These findings highlight several unmet needs among breast cancer survivors. Patients diagnosed with breast cancer face a myriad of survivorship issues throughout their lifespan. Among these are reproductive health concerns, which are encountered by an increasing number of younger breast cancer survivors and include issues surrounding fertility, pregnancy, and contraception. A particular gap in care is the limited access to evidence-based gynecological care, including contraceptive counseling for those not desiring pregnancy. A previous study 2 reported that many pregnancies among breast cancer survivors were unintended and occurred in women not planning to conceive. There are many reasons for this pattern, including the lack of adequate contraceptive counseling, the use of ineffective contraceptive methods, and the mistaken belief that cancer treatments may induce permanent infertility. 3 women, 1
