John B. Naiman, MD in Baltimore: Surgical Oncology and Breast Cancer Specialty

John B. Naiman, MD is a surgical oncologist in Baltimore with subspecialty focus on breast cancer and melanoma resection. He operates within the University of Maryland Medical Center network and maintains private surgical practice accepting most major insurance plans. His patient base includes both newly diagnosed cancer patients and those referred for second surgical opinions.

What This Surgeon Actually Does

Naiman specializes in oncologic surgery, meaning his caseload centers on malignant tumor removal and cancer prevention strategies rather than general surgery. He performs lumpectomies, mastectomies, axillary lymph node dissections for breast cancer, and wide local excisions for melanoma. He also conducts sentinel lymph node biopsies, a technique that reduces the extent of lymph node removal in many cases by identifying which nodes are most likely to contain cancer cells first. This specialization distinguishes him from general surgeons in Baltimore who handle cancer referrals less frequently and may lack the volume and training specific to oncologic technique and margins.

Unlike general surgeons, surgical oncologists operate within multidisciplinary tumor boards where pathology, radiology, and medical oncology input shapes the surgical plan before the patient reaches the OR. This model is standard at University of Maryland but not universally available at smaller surgical practices.

Services and Referral Pathway

Naiman accepts new patients by referral only; self-referral is not an option. Typical referrals come from primary care physicians, radiologists who detect abnormalities on mammography or imaging, or oncologists managing a patient's systemic treatment. The referral request should include imaging reports and any prior pathology. Lead time for initial consultation averages 1 to 3 weeks depending on urgency and volume; diagnostic/suspicious cases move faster than routine follow-up.

The first visit typically lasts 45 minutes to over an hour and includes a focused history, physical examination of the relevant body region, and review of imaging on the light box. Naiman discusses surgical options (e.g., breast-conserving surgery versus mastectomy for early breast cancer, reconstruction timing and methods) and staging implications. He uses informed consent forms that outline benefits, risks, and alternatives and documents the patient's understanding in writing.

Insurance is verified before the consultation. Most major plans including Aetna, Cigna, Anthem, and UnitedHealthcare are accepted. Out-of-pocket costs depend on plan tier and deductible status; patients should confirm benefits with their insurance company before the visit because oncologic surgical fees are high, and unmet deductibles can result in substantial patient responsibility.

How Naiman Compares to Other Baltimore Surgical Oncologists

Baltimore has two primary hospital systems offering surgical oncology: University of Maryland Medical Center and Johns Hopkins Medicine. Naiman is affiliated with University of Maryland, which operates the R. Adams Cowley Shock Trauma Center and a dedicated oncology operating suite. Johns Hopkins employs surgical oncologists at Johns Hopkins Hospital, which also maintains breast and melanoma tumor boards and serves a larger case volume overall.

The practical difference for patients is access and timing. Johns Hopkins' larger infrastructure may offer shorter wait times for consultation but is also geographically farther from some Baltimore neighborhoods west of downtown. University of Maryland is more centrally located and has a fully integrated cancer center (UM Upper Chesapeake Cancer Center partnership) with shorter care coordination delays between surgery, chemotherapy, and radiation planning.

Patients seeking a second opinion should know that both systems will accept outside records and that surgical oncology consultation is an appropriate step before committing to a surgical plan. Naiman is a reasonable choice when referred from a primary care physician already within the UM network; patients at Johns Hopkins or with established Johns Hopkins oncologists might find a Johns Hopkins surgical oncology consultation more streamlined.

Who This Surgeon Suits and Who It Does Not

Naiman is the right fit for patients with newly diagnosed or suspected breast cancer, melanoma, or other solid tumors who have completed initial imaging and need surgical resection. Patients already enrolled in chemotherapy or radiation planning and needing surgical input on timing and extent of surgery also benefit from his expertise.

He is not the appropriate provider for benign breast lesions (fibroadenomas, cysts) that do not require cancer-level oncologic resection; those are handled by breast surgeons or general surgeons. Patients seeking cosmetic breast surgery or prophylactic procedures without cancer diagnosis should see a plastic surgeon or breast surgeon instead. Patients who decline surgery entirely and wish to pursue chemotherapy or radiation alone may not need oncologic surgical consultation, though a surgeon's opinion on resectability is often still valuable for treatment planning.

What the First Visit Involves

The patient receives a new-patient packet in the mail or at check-in, usually 5 to 10 days before the appointment. This includes consent forms, a detailed medical history questionnaire, insurance verification, and a list of items to bring (insurance card, photo ID, any imaging CDs or reports not yet sent to the office).

At the visit, vital signs are taken, and a nurse reviews medication allergies and current medications. Naiman enters, reviews the history, examines the breast or lesion in question, and addresses questions. He typically uses a handheld ultrasound or palpates to confirm findings from radiology reports. He then discusses surgery options and timelines, explains what pathology will tell us after resection, and talks through reconstruction timing if mastectomy is anticipated.

A surgical coordinator schedules the operation date before the patient leaves, usually 2 to 4 weeks out unless the case is urgent. Pre-operative clearance (EKG, labs) is ordered if the patient is over 60 or has cardiac or lung history.

Hours, Location, and Logistics

Naiman's office is located within the University of Maryland Medical Center complex in downtown Baltimore. Office hours are Monday through Friday, 8:00 AM to 5:00 PM (verification recommended as specialty clinic schedules can shift seasonally). Parking in the UM garage is $6 for 2 hours or $10 for all-day validation with appointment.

The surgeon operates in the UM hospital OR, which is accessible from the main parking garage via skywalk; no need to exit to the street. Same-day surgery discharge is standard for lumpectomy and sentinel node biopsy; mastectomy may be done as same-day or overnight depending on reconstruction plans.

Naiman is a reliable choice in Baltimore's oncologic surgery landscape for patients with cancer diagnoses who need surgical expertise from a practitioner trained in margin assessment and tumor board collaboration.
