Breast Cancer Treatment in South Korea

Advanced Breast Cancer Surgery, Robotic Breast Surgery & Oncoplastic Breast Care in Seoul

Breast Cancer Treatment in Seoul, South Korea at Asan Medical Center offers international patients access to advanced breast cancer diagnosis, surgery, reconstruction planning, and multidisciplinary cancer care. Breast cancer surgery may include breast-conserving surgery, mastectomy, robotic breast surgery, oncoplastic breast surgery, lymph node assessment, and breast reconstruction when medically appropriate. Patients choose Asan Medical Center for breast cancer care because treatment is planned according to tumor type, cancer stage, imaging results, pathology findings, breast anatomy, and each patient’s long-term health needs. The goal is to remove cancer safely while supporting breast shape, physical recovery, emotional confidence, and coordinated follow-up care.

🔍 What Is Breast Cancer Treatment?

Breast cancer treatment is a medical and surgical care pathway designed to diagnose, remove, control, and manage cancer that develops in breast tissue.

The treatment plan depends on several factors, including tumor size, tumor location, lymph node involvement, hormone receptor status, HER2 status, genetic risk, overall health, and whether the cancer is early-stage, locally advanced, recurrent, or metastatic. Breast cancer surgery is often a central part of treatment for patients whose cancer can be surgically removed. Surgery may involve removing only the tumor and a margin of healthy tissue through breast-conserving surgery, or removing the whole breast through mastectomy when necessary. The surgical approach is selected after reviewing imaging, biopsy results, staging, breast size, tumor position, and patient preference. Robotic breast surgery and oncoplastic breast surgery may be considered for selected patients when clinically suitable. These techniques are not suitable for every patient, so eligibility must be confirmed after detailed assessment by the breast surgery team. Breast cancer treatment may also include chemotherapy, radiotherapy, endocrine therapy, targeted therapy, breast reconstruction, rehabilitation, and long-term follow-up.

🩺 Types of Breast Cancer Treatment & Surgery

Breast-Conserving Surgery – Removes the cancerous tumor and surrounding tissue while preserving most of the breast.
Mastectomy – Removes the entire breast when breast-conserving surgery is not suitable or not preferred.
Sentinel Lymph Node Biopsy – Checks the first lymph nodes likely to receive cancer spread from the breast.
Axillary Lymph Node Surgery – Removes lymph nodes from the underarm area when cancer spread is suspected or confirmed.
Robotic Breast Surgery – Uses robotic surgical technology in selected cases where this approach is medically appropriate.
Oncoplastic Breast Surgery – Combines breast cancer removal with reshaping techniques to support better breast contour.
Breast Reconstruction After Mastectomy – Restores breast shape using implant-based or tissue-based reconstruction when suitable.
Immediate Breast Reconstruction – Reconstruction performed during the same operation as mastectomy for eligible patients.
Delayed Breast Reconstruction – Reconstruction performed after cancer treatment, recovery, or additional therapy is completed.
Multidisciplinary Breast Cancer Treatment – Combines surgery, oncology, radiotherapy, imaging, pathology, rehabilitation, and long-term follow-up.

🩺 Who Is a Good Candidate?

Breast cancer treatment at Asan Medical Center may be suitable for patients who need expert evaluation, surgery, or a second opinion for confirmed or suspected breast cancer. The right treatment depends on accurate diagnosis and staging, so every patient requires a personalized review before a surgical plan is confirmed.

✔️ Patients with locally advanced breast cancer requiring multidisciplinary planning
✔️ Individuals who need breast cancer surgery in Seoul, South Korea
✔️ Patients considering breast-conserving surgery or mastectomy
✔️ Patients who may need robotic breast surgery if medically suitable
✔️ Patients interested in oncoplastic breast surgery for cancer removal and breast reshaping
✔️ Patients requiring lymph node evaluation or axillary surgery
✔️ Individuals seeking breast reconstruction after mastectomy
✔️ Patients who need chemotherapy, radiotherapy, endocrine therapy, or targeted therapy planning
✔️ Patients seeking a second opinion after biopsy, imaging, or previous treatment recommendations

📝 Consultation & Preparation

A detailed consultation and preparation process is essential before breast cancer surgery. The medical team must confirm the diagnosis, understand the tumor biology, review the patient’s general health, and decide whether surgery should be performed first or after systemic treatment.

✔️ Review of breast biopsy results and pathology report
✔️ Breast imaging review, including mammogram, ultrasound, MRI, CT, or PET-CT when required
✔️ Evaluation of tumor size, location, stage, and lymph node involvement
✔️ Review of hormone receptor status, HER2 status, and other tumor markers
✔️ Assessment by breast surgery specialists for surgical planning
✔️ Multidisciplinary review with oncology, radiology, pathology, radiation oncology, and plastic surgery when needed

🩺 Recovery & Aftercare

Recovery after breast cancer surgery depends on the type of operation, lymph node procedure, reconstruction plan, and whether additional treatment is required. Most patients need careful wound care, arm movement guidance, pain control, follow-up visits, and emotional support during the healing period.

✔️ Mild to moderate pain, swelling, tightness, and bruising may occur after surgery
✔️ Surgical drains may be used after mastectomy, lymph node surgery, or reconstruction
✔️ Patients receive instructions for wound care and drain care before discharge
✔️ Arm and shoulder movement may be limited at first and gradually improved
✔️ Rehabilitation guidance may help restore mobility and reduce stiffness
✔️ Patients should avoid heavy lifting and strenuous activity during early healing
✔️ Follow-up appointments are needed to review healing and pathology results
