Surgery

Is Dr. Vasilev a cancer doctor or an endometriosis surgeon?

The short answer

Dr. Vasilev is an endometriosis surgeon whose current practice is focused on endometriosis, not cancer care. He is also a fellowship-trained gynecologic oncologist, bringing advanced surgical training to complex endometriosis and adenomyosis surgery.

Dr. Vasilev practices full-time helping patients with endometriosis. He is also a fellowship-trained gynecologic oncologist and an expert in MIGS surgery. That background doesn’t mean his current practice focuses on cancer care. It reflects very advanced surgical training in complex pelvic anatomy and challenging operative situations, including scar tissue and recurrent disease. Beyond the training that average gynecologic oncologists receive, he has additional training and experience gained from mentors in urologic oncology and general surgery, as well as extensive ten-year experience in collaborative multidisciplinary surgeries as Director at the City of Hope.

That expertise translates directly to endometriosis and adenomyosis surgery, where it’s often critical to operate safely around the ureters, bowel, bladder, nerves, and major blood vessels, and to make sound decisions in densely scarred tissue. Today, our team’s work is dedicated entirely to endometriosis and adenomyosis care, and we welcome you to reach out if you’d like to discuss your symptoms and surgical options.

Questions people ask next

All surgery questions
  • How do I find a qualified endometriosis specialist?

    Look for surgeons who regularly treat complex endometriosis and can explain their training, surgical approach, and care for bowel or bladder involvement. Surgeon-vetting platforms and patient-reported experiences can help, but neither is perfect on its own.

  • Should I see a gyn, MIGS surgeon, or excision specialist for endometriosis?

    A general gynecologist may be a reasonable starting point for routine evaluation or medication, while an excision specialist is usually the most direct path for suspected complex disease. MIGS training alone does not automatically mean deep endometriosis excision expertise.

  • Why would endometriosis require a procedure like ovarian cancer surgery?

    Endometriosis may require an oncology-level approach in select, highly complex cases to safely and completely remove aggressive disease when anatomy is distorted and surgical risks are higher. Most people with endometriosis will never need a cancer-style operation.

  • What questions should I ask an endometriosis specialist?

    Ask which diagnoses they are considering and why, and what records or imaging would change your care plan. If surgery is on the table, ask about excision, confirming what was removed, care for affected organs, success for your goals, recovery, and follow-up.
