Mr Yazan Massanat

Mr Yazan Masannat is an award-winning, internationally recognised Consultant Oncoplastic Breast Surgeon providing comprehensive private breast care in London. He combines advanced breast cancer surgery with reconstructive and aesthetic techniques to offer patients safe, effective and cosmetically optimised treatment. His practice focuses on individualised, evidence-based care from diagnosis through to long-term follow-up, ensuring that each patient receives expert guidance at every step of their breast-health journey.

Mr Masannat is highly experienced in the full spectrum of breast disease. He provides rapid-access, one-stop breast clinic assessment for women experiencing breast symptoms, including breast lumps, cysts, fibroadenomas, breast pain (mastalgia), nipple discharge, nipple changes, infections, abscesses, mastitis, and axillary (armpit) lumps or lymph-node abnormalities. He also specialises in the assessment and management of high-risk lesions, lobular neoplasia, atypical hyperplasia, and screening-detected abnormalities, as well as supporting women with a significant family history or genetic predisposition who may require enhanced surveillance or risk-reducing strategies.

In his cancer practice, Mr Masannat treats the full range of breast cancer presentations — from early and screen-detected disease to complex, recurrent or locally advanced cancers. He is known for his expertise in breast-conserving surgery using precision localisation and oncoplastic techniques, allowing more women to preserve their breast without compromising cancer outcomes. When mastectomy is required, he offers a personalised discussion of reconstructive options, including implant-based reconstruction (with or without mesh/ADM) and referral for autologous flap reconstruction where appropriate. He also performs revision and symmetrisation surgery for patients who have undergone previous breast cancer treatment elsewhere, aiming to improve contour, symmetry and cosmetic outcome.

His surgical expertise includes:

• Breast-conserving surgery (lumpectomy, wide local excision, segmentectomy)

• Therapeutic mammoplasty, breast reduction and oncoplastic reshaping

• Mastectomy (simple, skin-sparing, nipple-sparing, risk-reducing/prophylactic)

• Immediate and delayed breast reconstruction (implant-based; collaborative autologous options)

• Revision surgery after previous reconstruction or radiotherapy

• Lipomodelling / fat transfer for contour correction

• Symmetrisation surgery (reduction, mastopexy, augmentation as indicated)

• Sentinel lymph node biopsy, targeted axillary dissection and axillary clearance

• Excision of benign breast lumps and cysts

• Surgery for nipple problems, duct excision and evaluation of discharge

• Management of axillary lumps, lymph nodes and accessory breast tissue

Beyond his clinical practice, Mr Masannat is deeply committed to advancing the field of breast surgery. He is the founder and editor of iBreastBook, a global educational platform followed by thousands of surgeons worldwide. He serves as an examiner for the European Board of Surgical Oncology and Breast Surgery and holds academic appointments at the University of Aberdeen, Queen Mary University of London and Anglia Ruskin University. He has authored more than 70 peer-reviewed publications, leads major international research collaborations, and contributes to national and international guidelines — ensuring his patients benefit from the most up-to-date, evidence-driven care.

With his combination of surgical expertise, academic leadership and a compassionate, patient-centred approach, Mr Masannat provides a comprehensive and personalised breast service at One Welbeck. His philosophy is that optimal breast cancer care should achieve both oncological safety and the best possible aesthetic outcomes, giving women confidence, clarity and reassurance throughout their treatment journey.
