Breast and Endocrine Surgery
The Department of Breast and Endocrine Surgery diagnoses and treats mammary gland diseases as well as thyroid and parathyroid diseases. Mammary gland disorders range from malignant tumors including breast cancer, phyllodes tumors, and growing benign tumors. Thyroid and parathyroid diseases include thyroid cancers and tumors, as well as parathyroid adenomas.
Medical services
Specialists and certified physicians affiliated with the Japan Surgical Society and the Japanese Breast Cancer Society, as well as highly experienced specialized physicians affiliated with the Japan Association of Endocrine Surgeons and Japanese Society of Thyroid Surgery carry out diagnosis, surgery, and drug therapy (chemotherapy, molecular targeted therapy and hormone therapy).
Treatment policy
When providing medical services, we place utmost value on each patient’s feelings, thoughts and lifestyle. The most appropriate treatment method is selected by a group of specialists based on a careful review of the results of detailed and precise examinations, and this is thoroughly explained to patients before embarking on the course of treatment.
Specialized areas
Suitable treatment based on close cooperation between Breast and Endocrine Surgery, Radiology, Pathology, Plastic, Reconstructive and Aesthetic Surgery, Nephrology and Endocrinology, and the Department of Clinical Genomics
The best course of treatment is determined by reaching a diagnosis through ultrasound examination, mammography, cytology, needle biopsy, mammotome biopsy, CT and MRI, and by closely coordinating with other departments.
Deciding on a treatment based on abundant experience and explaining
Patients are given information that helps them fully understand the treatment before drug therapies such as anticancer chemotherapy and radiation therapy are carried out.
- When necessary, the optimum measure to prevent recurrence is considered through multigene assays (such as Oncotype DX).
Target diseases
Breast cancer, mammary gland cancer, phyllodes tumor, fibroadenoma, intraductal papilloma, other mammary gland tumors, hereditary breast and ovarian cancer, thyroid cancer (papillary cancer, follicular thyroid cancer, medullary cancer, undifferentiated cancer), follicular goiter, adenomatoid goiter, Grave’s disease, other thyroid tumors, parathyroid adenoma.
Advanced treatments/ Specialized treatments
Breast cancer treatment
For patients who require breast reconstruction after a total mastectomy, reconstructive mammoplasty and tissue expander insertion surgery are performed in cooperation with Plastic, Reconstructive and Aesthetic Surgery.
Advice on concealing scars with makeup
After surgery, doctors will advise patients about how they can conceal chemotherapy-induced hyperpigmentation with makeup.
- We place particular emphasis on the treatment of hereditary breast and ovarian cancer syndrome. We coordinate with genomic cancer medicine programs such as the Todai OncoPanel test.
- A team of Obstetrics and Gynecology specialists will be on hand to discuss whether younger patients want children and wish to opt for fertility-sparing surgery before they commence with breast cancer treatment.
