Nancy Markus, MD in Baltimore: Surgical Oncology with Breast Cancer Focus

Nancy Markus is a surgical oncologist based in Baltimore who specializes in breast cancer surgery and reconstruction. She operates within the academic and clinical infrastructure of Johns Hopkins Medicine, one of the city's two dominant hospital systems, and brings subspecialty depth in a field where many general surgeons in the region handle breast cases as part of a broader practice.

What She Treats and Surgical Scope

Markus focuses on surgical management of breast cancer, including lumpectomy, mastectomy, and complex reconstruction cases involving implants or autologous tissue transfer. She also manages benign breast conditions and works with patients who carry genetic predisposition (BRCA mutations). Her training and ongoing practice emphasize oncologic safety paired with functional and aesthetic outcome, a distinction that matters because breast reconstruction timing and technique vary widely across surgeons in Baltimore.

Referral, Consultation, and Getting Started

Markus operates within the Johns Hopkins system, which means most patients arrive through referral from a primary care physician or after imaging work-up at a Johns Hopkins facility or partner center. New patients typically begin with a consultation appointment that includes review of imaging, discussion of diagnosis and staging, and treatment planning. If you have been diagnosed at a separate facility—such as Mercy Medical Center or University of Maryland Medical System, the other major Baltimore systems—your oncologist or primary care doctor will manage the referral process.

Initial consultation appointments generally run four to six weeks out during typical periods, though availability shifts seasonally; confirm directly with the scheduling office. Markus participates in Johns Hopkins' tumor board review, meaning complex cases are discussed with radiologists, medical oncologists, and other surgical specialists before surgery is scheduled. This multidisciplinary model is standard at Johns Hopkins but less consistent at smaller independent practices in Baltimore.

Insurance and Cost Baseline

Markus accepts major commercial insurance plans, Medicare, and Medicaid. The surgical fee for mastectomy with reconstruction ranges from $8,000 to $15,000 depending on reconstruction method and complexity; lumpectomy alone runs lower. These figures reflect surgeon and facility charges only and do not include anesthesia, pathology, or implant costs if applicable. Verify your deductible, out-of-pocket maximum, and whether Johns Hopkins facilities are in-network for your plan before scheduling. Hospital-based charges often exceed surgeon fees substantially.

How She Compares to Other Baltimore Surgical Oncologists

Baltimore has a small but active surgical oncology community. Johns Hopkins employs multiple breast surgical oncologists; Markus is one of the most established but not the only option within that system. Mercy Medical Center and University of Maryland Medical System also employ surgeons with breast cancer focus, though those systems' academic partnerships and tumor board infrastructure differ from Johns Hopkins. A key difference: Johns Hopkins maintains formal breast cancer center accreditation and standing tumor boards that include genomic testing and reconstruction specialists; smaller community practices may lack the same coordination.

If you are already receiving oncology care at Mercy or UMD, staying within that system often makes scheduling and care coordination simpler. If you are newly diagnosed or switching systems, Johns Hopkins' depth in complex reconstruction cases and access to clinical trial options is an advantage, particularly for younger patients or those with unusual histology.

First Visit and What to Bring

Your first appointment will cover pathology review, imaging interpretation, and staging confirmation. Bring any biopsy reports, imaging discs (or request they be sent ahead), and a current medication list. Most consultations run 45 minutes to an hour. If reconstruction is being considered, discussion of implant options, autologous techniques, and timing will occur; this can be dense, and taking notes or bringing a support person is practical. Markus typically does not perform surgery immediately after a single consultation; a second appointment or tumor board discussion often precedes scheduling.

Office Hours and Logistics

Markus operates out of a Johns Hopkins clinic location in Baltimore; specific office hours vary by season and should be confirmed by calling the Johns Hopkins scheduling line or visiting the Johns Hopkins Medicine website. Parking at Johns Hopkins hospitals and outpatient centers in Baltimore runs $8 to $12 per visit; some facilities offer validation for surgical consultations. Allow extra time for parking and check-in if you are unfamiliar with the campus.

Who This Approach Suits Best

Markus' practice fits patients with newly diagnosed breast cancer who value tumor board oversight and access to reconstruction specialists without additional referrals, as well as those with complex presentations (recurrent disease, genetic predisposition, high-risk lesions) where multidisciplinary input is standard. Her Johns Hopkins affiliation is less necessary if you need a straightforward lumpectomy and prefer a surgeon closer to your home or already embedded in another system.

Markus' Baltimore position reflects the city's concentration of surgical oncology expertise at three major systems, none of which are distributed evenly across neighborhoods. If you live in outer Baltimore County, University of Maryland's Columbia campus may have shorter travel time.
