Some studies suggest that pregnancy may increase the risk of metastatic breast cancer and delay diagnosis, while other studies indicate that pregnancy does not directly accelerate breast cancer progression and does not negatively impact outcomes after treatment.

Breast cancer during pregnancy is a complex and challenging condition, raising concerns about whether pregnancy influences the progression and prognosis of breast cancer. This synthesis aims to analyze the relationship between pregnancy and breast cancer progression based on multiple research studies.
Advanced Stage at Diagnosis:
Transient Increase in Risk Post-Childbirth:
Survival Rates:
Impact of Subsequent Pregnancies:
Hormonal Influence and Tumor Growth:
Protective Long-term Effect:
Pregnancy appears to be associated with a higher likelihood of presenting with advanced breast cancer due to diagnostic delays. There is a transient increase in breast cancer risk shortly after childbirth, particularly in older first-time mothers. However, survival rates for pregnant women with breast cancer are comparable to those of non-pregnant women, and subsequent pregnancies do not negatively impact overall survival. In the long term, pregnancy may offer protective benefits against breast cancer.
