Discovering a new lump while pregnant can be alarming. Pregnancy is a time of enormous physical change, and many of those changes can cause lumps or bumps that are benign. Still, it’s important to know which findings are likely harmless, which require prompt evaluation, and how care is safely delivered during pregnancy. This guide explains common causes of lumps in pregnancy, how clinicians evaluate them, diagnostic options that protect the baby, and when to seek urgent care versus routine follow-up. It also describes how telehealth, including services like Doctronic.ai, can help provide fast, expert guidance when questions arise.
Why Lumps Can Appear or Feel Different During PregnancyPregnancy triggers profound hormonal and physiologic changes that affect nearly every tissue in the body. Rising levels of estrogen, progesterone, and prolactin change the breasts, lymphatic fluid balance, and skin. Blood volume increases, veins dilate, and immune responses shift to protect the fetus. These normal changes can alter the size, texture, and sensitivity of glands and tissues, making previously unnoticed lumps easier to detect.
For example, breasts enlarge and become denser as milk-producing glands grow; lymph nodes can feel more prominent because of increased immune activity; and hormonal cysts may form or enlarge in the ovaries. Understanding this context reduces unnecessary fear while still prompting appropriate evaluation for anything new, rapidly growing, or painful.
Lumps found during pregnancy fall into several general categories: benign breast changes, inflammatory processes, cysts and fluid collections, enlarged lymph nodes, skin and soft-tissue masses, and, more rarely, tumors. Each has distinct features that guide the next steps.
Breast lumps are among the most common concerns during pregnancy. The most frequent benign causes include fibroadenomas (benign tumors of glandular tissue), galactoceles (milk-filled cysts that can occur once milk production starts), and cysts or fibrocystic changes. Mastitis, an infection of breast tissue, causes a tender, red, warm lump often accompanied by fever.
Although breast cancer during pregnancy is uncommon, it does occur. Breast cancer diagnosed in pregnancy tends to be detected at a later stage because physiological breast changes can mask tumors. Statistically, pregnancy-associated breast cancer occurs in roughly 1 in 2,500 to 1 in 3,000 pregnancies, depending on population studies. Any firm, fixed, rapidly growing, or skin-adherent lump requires prompt evaluation regardless of pregnancy status.
Ovarian cysts are common in early pregnancy because of normal follicle development. Many of these cysts resolve spontaneously. Persistent cysts or complex ovarian masses may require ultrasound monitoring, and rarely surgical removal if large, symptomatic, or suspicious. Pain, sudden severe abdominal pain, or signs of internal bleeding are reasons for immediate emergency evaluation.
Lymph nodes commonly enlarge in response to infections or inflammation. During pregnancy, shifts in the immune system can make nodes feel more prominent. Typical benign nodes are soft, mobile, and tender. Hard, fixed, or progressively enlarging nodes warrant further assessment, particularly if accompanied by systemic symptoms like unexplained weight loss, night sweats, or prolonged fever.
Pregnancy can produce vascular changes such as spider veins, varicosities, and benign vascular tumors like hemangiomas. Hormonal influences can also cause cysts in the skin or fatty lumps (lipomas). Most of these are harmless; biopsy or imaging is rarely necessary unless the lesion is growing rapidly or causing functional problems.
Evaluation balances the need to diagnose with the safety of the mother and fetus. The standard approach begins with a careful history and targeted physical exam to understand onset, growth, symptoms (pain, redness, fever, nipple discharge), and any relevant personal or family history of cancer.
Next steps typically include imaging and, when needed, tissue sampling. The specific modality depends on the lump’s location and characteristics.
Ultrasound is the first-line imaging test for most lumps in pregnancy because it does not use ionizing radiation and provides excellent detail for soft tissues, breasts, and pelvic organs. For breast lumps, a diagnostic ultrasound can often distinguish cystic from solid lesions and guide fine-needle aspiration if fluid removal is needed.
Mammography uses low-dose radiation and is safe in pregnancy when clinically indicated; a fetal lead shield is used to minimize exposure. Mammography may be considered when ultrasound findings are suspicious or when a more complete evaluation of the breast is required. MRI without gadolinium contrast can sometimes be used for specific situations, though gadolinium is typically avoided in pregnancy unless absolutely necessary.
If imaging suggests a suspicious mass, a biopsy may be recommended. Core needle biopsy is the usual method for solid breast masses and can be performed safely during pregnancy with local anesthesia. Biopsy results drive management decisions, whether continued surveillance, surgery, or oncology referral is needed.
Not all lumps require emergency care. However, certain signs should prompt immediate medical attention:
Rapidly growing mass
Severe or worsening pain
Redness, warmth, or fluctuance that suggests an abscess
Fever or systemic symptoms
Sudden abdominal pain, especially with dizziness or fainting (possible ovarian torsion or bleeding)
Skin changes such as ulceration or sudden dimpling
For non-urgent but concerning lumps, for example, a small, stable breast lump, arranging prompt outpatient evaluation is appropriate. Telehealth can be an excellent first step to triage symptoms, get an immediate expert opinion, and learn which local tests or clinics are most appropriate.
Telehealth combines convenience with specialist input that can reduce anxiety and accelerate care. Doctronic.ai offers immediate AI-driven visits for free and affordable video visits with clinicians around the clock in all 50 states, providing an accessible starting point if a lump is found during pregnancy. Using a telehealth visit, the clinician can take a detailed history, view photos if appropriate, triage urgency, and arrange safe in-person imaging or lab testing when needed.
Doctronic’s model, offering free AI evaluations and inexpensive telehealth video visits for under $40, can be particularly useful for pregnant people who need quick guidance outside regular clinic hours, or who want to prepare for a targeted in-person exam. Doctronic.ai draws on contemporary medical literature to deliver evidence-informed recommendations, and its clinicians can help navigate next steps like ultrasound scheduling or urgent care referrals when necessary.
Treatment decisions during pregnancy take the health of both the pregnant person and the fetus into account. Many benign conditions are managed conservatively until after delivery if it is safe to do so. For infections, antibiotic choices are guided by safety data in pregnancy. Abscesses may be drained promptly to prevent spread, using techniques that protect fetal well-being.
When a malignant diagnosis is made, multidisciplinary teams coordinate care. Surgery can often be performed safely during pregnancy, with timing and technique tailored to minimize risks. Certain chemotherapy agents are used in the second and third trimesters when necessary; radiation therapy is generally avoided during pregnancy unless absolutely essential. These decisions require careful, individualized counseling by maternal-fetal medicine specialists and oncologists.
Benign-appearing lumps that are not immediately concerning are usually followed by interval clinical exams and repeat imaging. Ultrasound follow-up intervals vary but commonly occur in 4–12 weeks to confirm stability or resolution. A clear communication plan should be established: if the lump changes in size or symptoms develop, expedited reassessment is needed.
Documentation of findings is helpful for postpartum care. For breast lumps, keeping records of ultrasound images and clinic notes ensures the postpartum clinician can compare and avoid unnecessary repeat testing unless indicated.
Take these practical steps to ensure timely and appropriate care:
Note when the lump was first discovered, any recent changes, and associated symptoms (pain, discharge, fever).
Use telehealth for immediate triage if an in-person visit is not immediately available. Services such as Doctronic.ai provide rapid AI assessments and low-cost video visits to help determine urgency and next steps.
Seek same-day care for red flags (severe pain, fever, rapid growth, sudden abdominal pain, or bleeding).
Ask for ultrasound-based imaging when appropriate, because ultrasound avoids radiation and often clarifies whether a mass is cystic or solid.
If a biopsy is recommended, discuss timing and method; core needle biopsy is typically safe during pregnancy when indicated.
Emotional and Practical Support During EvaluationFinding a lump while pregnant can trigger anxiety about both personal health and the baby. Clear communication, fast access to reliable information, and coordinated care reduce stress. Telehealth platforms can provide immediate reassurance, explain expected steps, and set realistic timelines for testing and results. Family members or partners can be included in remote visits when needed to help with decision-making and emotional support.
Insurance coverage, workplace leave, and childcare for other children are practical matters that often accompany medical visits. Early communication with the healthcare team about scheduling and required testing can minimize disruptions and help plan for follow-up visits or procedures.
Second opinions are appropriate if imaging or biopsy results are unclear, if a proposed treatment feels rushed, or if a rare diagnosis is being considered. During pregnancy, the stakes can feel especially high, so seeking additional input from subspecialists (maternal-fetal medicine, surgical oncology, or breast specialists) is reasonable. Telehealth makes obtaining second opinions easier and can speed access to specialty expertise without extensive travel.
Most lumps found during pregnancy are benign, but rules for safety and prompt diagnosis still apply. Ultrasound is the primary diagnostic tool in pregnancy; mammography and biopsy can be used safely when indicated. Rapidly growing, painful, or symptomatic lumps deserve urgent evaluation. Telehealth services, including immediate AI assessments and low-cost video visits like those provided by Doctronic.ai, can provide quick triage, evidence-based guidance, and expedited referrals to imaging or in-person care.
