Summary
Breast cancer during pregnancy does not alter the disease's natural course. Treatment must prioritize fetal safety, with specific timing and drug choices for chemotherapy and radiotherapy.
Area of Science:
- Oncology
- Maternal-Fetal Medicine
- Reproductive Health
Background:
- Breast cancer diagnosis during pregnancy is uncommon but presents complex management challenges.
- The biological interaction between pregnancy and breast cancer is minimal, with no evidence of altered disease progression.
Purpose of the Study:
- To review the relationship between breast cancer and pregnancy.
- To outline safe and effective treatment strategies for breast cancer diagnosed during pregnancy.
- To address the psychosocial impact on patients and families.
Main Methods:
- Literature review of epidemiological, clinical, and prognostic studies.
- Analysis of treatment guidelines considering fetal safety.
- Discussion of diagnostic and therapeutic challenges.
Main Results:
- Pregnancy does not biologically influence breast cancer's natural history.
- Effective breast cancer treatment is feasible during pregnancy with careful modality selection.
- Adjuvant radiotherapy is contraindicated during pregnancy; chemotherapy should be delayed until after the first trimester, avoiding specific antimetabolites.
Conclusions:
- Breast cancer and pregnancy are generally independent events.
- Treatment decisions must balance maternal oncologic needs with fetal well-being.
- Comprehensive medical and emotional support is crucial for affected women.
