Mastectomy

Mastectomy removes the entire breast tissue while lumpectomy (breast-conserving surgery) removes only the tumor with a margin of healthy tissue. For early-stage breast cancer, there is no survival difference between the two approaches—20-year breast cancer death rates are 8.5% for lumpectomy with radiation versus 9% for mastectomy. Choice factors include tumor size, breast size, patient preference, and access to radiation therapy. Mastectomy is preferred for multicentric disease, large tumor-to-breast ratio, prior radiation, or patient choice.

Five main types: (1) Simple/Total Mastectomy removes entire breast including nipple-areolar complex; (2) Skin-Sparing Mastectomy preserves breast skin for reconstruction; (3) Nipple-Sparing Mastectomy preserves both nipple and skin envelope with 0-3.7% recurrence rate for eligible patients; (4) Modified Radical Mastectomy includes axillary lymph node dissection for node-positive disease; (5) Radical Mastectomy (rarely performed) removes breast, chest wall muscles, and all axillary nodes. Thai hospitals offer all five types, with Vejthani providing all 6 variants including bilateral prophylactic mastectomy.

Immediate reconstruction occurs at the same surgery as mastectomy—benefits include one surgery/anesthesia, better cosmesis, and preserved skin envelope. Delayed reconstruction occurs months to years later—benefits include allowing adjuvant therapy first and more decision time. A third option, delayed-immediate (2-stage), places a tissue expander at mastectomy with definitive reconstruction later—best when radiation need is uncertain. Radiation to immediate reconstruction can affect cosmetic outcomes, so sentinel node biopsy BEFORE reconstruction helps assess radiation need.

Two main categories: Implant-based (silicone/saline, 1-2 hour surgery, 4-6 week recovery) and Autologous tissue flaps. Flap options include DIEP (abdominal tissue, muscle-sparing, 6-8 hours, natural results), TRAM (abdominal with muscle, abdominal weakness risk), and Latissimus Dorsi (back muscle, often needs implant for volume). Thai hospitals offer advanced options—Vejthani provides DIEP, TRAM, LD, PAP, TUG, SIEA, IGAP, and SGAP flaps. MedPark offers super microsurgery lymphaticovenular bypass for lymphedema patients.

BRCA1 mutation carriers face 72% cumulative lifetime breast cancer risk by age 80; BRCA2 carriers face 69% risk (per Kuchenbaecker et al., JAMA 2017). Bilateral prophylactic mastectomy reduces breast cancer risk by 90-95%. However, alternatives exist: enhanced surveillance (MRI/mammography alternating every 6 months) or chemoprevention (tamoxifen, raloxifene). Genetic counseling is essential before prophylactic surgery. Multiple Thai hospitals offer comprehensive BRCA1/2 testing—Vejthani also tests p53 and PTEN mutations.

Recommended stays vary by procedure: Simple mastectomy (no reconstruction) 2-3 weeks; Modified radical mastectomy 3-4 weeks; Mastectomy with implant reconstruction 4-6 weeks; Mastectomy with DIEP flap reconstruction 6-8 weeks. CDC recommends delaying air travel 10-14 days after major surgery. DVT risk is elevated for 4-6 weeks post-surgery; cancer increases VTE risk 9-fold per NCCN Guidelines 2024, with additional risk from surgery and prolonged immobility during flights. Graduated compression stockings and prophylactic anticoagulation may be recommended.

Five-year relative survival rates by SEER staging (2014-2020 data): Localized 100%, Regional 86-87%, Distant 29-32% (per NCI SEER Cancer Statistics 2024). The overall 5-year relative survival for all stages combined is 91%. Importantly, mastectomy and lumpectomy with radiation show no survival difference for early-stage disease (per Fisher et al., NSABP B-06, NEJM 2002)—choice depends on tumor characteristics and patient preference.

Lymphedema is permanent arm swelling due to lymphatic system damage. Risk is approximately 5% with sentinel node biopsy only but 17-31% with full axillary lymph node dissection plus radiation (per JCO 2009, meta-analysis 2023). Prevention includes sentinel node biopsy when possible (avoids full dissection in most patients), arm exercises, avoiding blood draws/BP measurements on affected arm, and prompt treatment of arm infections. Note: Air travel is NOT associated with increased lymphedema risk per systematic reviews; however, VTE (blood clot) risk is elevated post-surgery—these are different conditions requiring different precautions. MedPark offers super microsurgery lymphaticovenular bypass for lymphedema patients.

Immediate concerns requiring medical attention: fever, excessive redness, purulent drainage (infection signs); significant bleeding or hematoma expansion. Long-term warning signs: new lumps in chest wall, remaining breast, or axilla; persistent bone pain; shortness of breath or chest pain; persistent headaches; unexplained weight loss; jaundice or abdominal pain. Routine drain management includes emptying and measuring output 2-3x daily—drains typically removed when output <30cc/24 hours (1-3 weeks post-surgery).

Thailand costs (2025-2026 hospital published rates): Simple mastectomy $3,000-$7,000; Modified radical mastectomy $9,000-$12,000; With implant reconstruction $10,000-$15,000; With DIEP flap $15,000-$20,000; Bilateral prophylactic $6,000-$14,000. US costs (per CostHelper/MDsave 2024): Simple mastectomy $15,000-$55,000; Double mastectomy $20,000-$70,000; Total with reconstruction $30,000-$85,000. Bangkok Hospital publishes transparent packages: Modified Radical Mastectomy THB 294,000 (~$8,200 at THB 35.8/USD) including 4-night stay. Cost savings: 60-80% in Thailand versus USA.

Essential documents include: Complete operative report; Pathology report (tumor type, size, grade, margins, receptor status, node status); Discharge summary; Imaging studies on CD/USB; Medication list with dosages; Follow-up recommendations and timeline; Emergency contact information for Thai medical team; Letter for airline if traveling with drains. Video consultations with Thai surgeons are available for post-operative questions. Coordinate with home oncologist for ongoing care including adjuvant therapy planning.

A companion is required for the first 1-2 weeks minimum. They provide assistance with drain care, medication management, and transportation. Caregivers should be trained in drain management before hospital discharge. Emotional support is particularly important during recovery. For extended stays (DIEP flap reconstruction requiring 6-8 weeks), consider companion scheduling if the same person cannot stay the entire time.

All 7 major hospitals offer comprehensive mastectomy services with JCI accreditation (verified January 2026). Bangkok Hospital (Wattanosoth Cancer Hospital) specializes in endoscopic breast surgery and publishes transparent pricing. MedPark lists 13+ breast surgeons and offers super microsurgery for lymphedema. Vejthani provides comprehensive mastectomy options plus extensive flap reconstruction. Bumrungrad's Horizon Cancer Center provides multidisciplinary tumor board coordination. Samitivej offers oncogenetic screening. Choice depends on reconstruction preferences, specific surgeon expertise, and pricing transparency. Verify current services directly with hospitals.
