General Principles
Modern cancer-in-pregnancy care emphasizes accurate diagnosis, appropriate staging, pregnancy-compatible imaging, trimester-aware treatment planning, and maternal-centered shared decision-making.
Clinical points
- Pregnancy should not automatically delay necessary cancer diagnosis or treatment.
- Management decisions depend on disease biology, gestational age, urgency of treatment, and patient preferences.
- Cancer during pregnancy is best managed through coordinated multidisciplinary care.
- Delivery timing should be individualized rather than scheduled only for oncologic convenience when avoidable.

The original legacy page depended heavily on older Medscape and publisher URLs. This version shifts to current NCI PDQ, ASCO, FIGO, and ESMO resources that are more stable and more aligned with contemporary practice.
Adnexal Masses in Pregnancy
Most adnexal masses in pregnancy are benign, but persistent, complex, or symptomatic masses may require imaging follow-up or surgical evaluation.
Clinical points
- Risk assessment depends on ultrasound morphology, symptoms, growth, and gestational timing.
- Torsion, rupture, or concerning malignant features may require operative management.
- Persistent complex masses should be evaluated in the context of maternal symptoms and oncologic risk.
Breast Cancer
Breast cancer is one of the most common cancers diagnosed during pregnancy. Current care focuses on timely diagnosis, breast imaging adapted to pregnancy, surgery when indicated, and trimester-specific systemic therapy planning.
Clinical points
- Persistent breast mass in pregnancy should not be attributed to pregnancy changes without evaluation.
- Surgery is generally feasible during pregnancy when indicated.
- Chemotherapy decisions depend on gestational age and regimen; first-trimester exposure raises different concerns than later treatment.
- Radiation and endocrine-targeted issues require individualized planning.
Cervical Cancer
Cervical cancer diagnosed in pregnancy requires stage-specific counseling with attention to gestational age, maternal priorities, colposcopy and biopsy findings, imaging, and possible neoadjuvant approaches in selected cases.
Clinical points
- Preinvasive cervical lesions are usually managed differently from invasive cancer during pregnancy.
- Biopsy and MRI-based staging can be important when invasive cancer is suspected.
- Management depends on stage, nodal assessment, fetal viability, and patient goals.
- Cases benefit from gynecologic oncology and maternal-fetal medicine collaboration.
Gestational Trophoblastic Disease
GTD includes hydatidiform mole and gestational trophoblastic neoplasia. Modern management relies on structured diagnosis, hCG surveillance, risk scoring, and referral pathways for persistent or high-risk disease.
Clinical points
- Complete and partial mole require follow-up of hCG trends and attention to persistent trophoblastic disease risk.
- Gestational trophoblastic neoplasia management depends on risk stratification and disease type.
- Specialized centers improve consistency of care for persistent or metastatic disease.
- Contraception and follow-up planning remain important during surveillance.
Melanoma
Melanoma is one of the more frequently encountered non-gynecologic malignancies in pregnancy. Evaluation focuses on prompt biopsy of suspicious lesions and stage-appropriate imaging and surgery.
Clinical points
- Pregnancy should not delay biopsy of concerning pigmented lesions.
- Staging and treatment planning depend on lesion depth, nodal status, and metastatic risk.
- Placental and fetal considerations are relevant in advanced maternal melanoma.
Lymphoma
Lymphoma during pregnancy ranges from indolent disease that may occasionally allow limited delay to aggressive disease that often requires treatment during pregnancy.
Clinical points
- Hodgkin lymphoma and non-Hodgkin lymphoma have different biologic and treatment considerations.
- Aggressive lymphoma generally should not be deferred solely because of pregnancy.
- Treatment planning depends on histology, stage, symptoms, gestational age, and maternal condition.
- Hematology-oncology involvement is essential.
Sarcoma
Sarcoma in pregnancy is rare, so most management is individualized and referral-based. Soft tissue, bone, and gynecologic sarcomas may present different maternal and fetal concerns.
Clinical points
- Prompt tissue diagnosis and specialist referral are important because sarcoma subtype strongly affects management.
- Imaging and surgery may be feasible during pregnancy depending on location and urgency.
- Multidisciplinary treatment planning is especially important given limited pregnancy-specific evidence.
