Microwave Tumor Ablation (MWA)
Precision heat treatment for tumors without major surgery
About Microwave Ablation
MWA uses targeted microwave energy to heat and destroy tumor cells while sparing healthy tissue. This minimally invasive technique is guided by real-time imaging for precision treatment.
How It Works
Microwaves create friction in water molecules, generating heat that destroys tumor cells
Treatment Areas
Liver, kidney, lung, breast, thyroid, and bone tumors
Common Treatment Applications
Liver Tumors
- • Hepatocellular carcinoma
- • Metastatic liver tumors
- • Tumors ≤5cm
Breast Tumors
- • Early-stage breast cancer
- • Benign fibroadenomas
- • ≤2cm tumors
Thyroid Nodules
- • Benign symptomatic nodules
- • Small thyroid cancers
- • Recurrent nodules
The MWA Procedure
1
Preparation
Imaging (CT/Ultrasound/MRI) locates the tumor. Local anesthesia is administered at the insertion site.
2
Probe Placement
A thin microwave antenna is inserted through the skin directly into the tumor under image guidance.
3
Ablation
Microwave energy is delivered for 5-10 minutes, creating a 3-5cm sphere of ablation.
Advantages
- ✓Minimally invasive (no large incisions)
- ✓Preserves healthy tissue
- ✓Outpatient procedure
- ✓Repeatable if needed
Considerations
- •Not suitable for all tumor types/sizes
- •Risk of thermal injury to nearby structures
- •Possible post-procedure pain/discomfort
- •May require multiple sessions
