Pregnancy and breast cancer

Area of Science:

• Oncology
• Reproductive Medicine
• Surgical Oncology

Background:

• Breast cancer during pregnancy and lactation is uncommon but poses significant therapeutic challenges.
• The prognosis for these patients is often poorer due to delayed diagnosis and more advanced disease stages.

Observation:

• Physician delay in diagnosis and therapy is a critical factor contributing to poorer outcomes.
• Early mastectomy in pregnancy can be as effective as in nonpregnant women.
• Prompt evaluation of breast masses during pregnancy/lactation via biopsy is crucial.

Findings:

• Concurrent pregnancy and breast cancer necessitate immediate cancer treatment.
• Pregnancy interruption is generally not beneficial for non-disseminated breast cancer.
• Delayed therapy for disseminated disease near term may be considered based on patient desire for childbirth.
• Subsequent pregnancies are contraindicated after mastectomy with axillary spread.
• Future pregnancies appear safe after a 2-year disease-free observation period post-mastectomy.

Implications:

• Modern diagnostic and treatment methods can lead to effective outcomes for PABC.
• The previously pessimistic outlook for PABC is increasingly unjustified.
• Careful patient selection and monitoring are key for managing PABC and future pregnancies.
