Woman conceives via IVF, battles breast cancer during pregnancy, delivers healthy baby

A 45-year-old woman in Tainan City has successfully navigated a challenging journey of IVF conception, childbirth, and breast cancer treatment. After years of trying, she finally became pregnant via IVF, only to discover a rapidly growing lump in her right breast at five weeks gestation.

Subsequent tests confirmed the diagnosis of invasive mucinous breast cancer. A specialized medical team devised a tailored treatment strategy, incorporating surgery during her pregnancy and chemotherapy following the birth of her child. This approach allowed her to deliver a healthy baby girl. Two years into her follow-up care, there have been no indications of cancer recurrence.

Dr. Lin Yi-lun from Chi Mei Hospital's Department of Obstetrics and Gynecology emphasized the rising trend of later-life pregnancies and the increasing incidence of breast cancer among younger women. He addressed concerns some women have about ovulation induction medications potentially causing breast cancer, citing current guidelines and international studies that show no increased risk of invasive breast cancer associated with these drugs.

Breast cancer is the leading cause of cancer incidence among women in Taiwan, with over 17,000 new cases annually. Dr. Lin highlighted the critical importance of pre-pregnancy breast health check-ups, especially as women are delaying childbirth. He noted that hormonal changes during pregnancy can cause breast enlargement, potentially masking early signs of cancer and delaying diagnosis. Women with high-risk factors, such as a family history of breast cancer, early menarche, or no prior pregnancies, are urged to be particularly vigilant and undergo regular screenings.

Women should proactively undergo breast health examinations before preparing for pregnancy or starting infertility treatments to grasp their personal health status early, which can effectively reduce the risk and treatment difficulties of discovering cancer during pregnancy.
