About this approach
Tumor Treating Fields use wearable arrays placed on the skin to deliver alternating electric fields to a tumor region. The treatment is used for specific diagnoses and is worn for many hours each day, usually alongside other cancer care. It is different from radiation, electrical tumor ablation, and implanted stimulation devices.
Where it fits: Device-based treatment for selected brain, lung, and mesothelioma settings
Where this treatment is used
FDA-authorized TTFields devices have disease-specific indications, including glioblastoma, malignant pleural mesothelioma, and selected metastatic non-small cell lung cancer settings. Device use, accompanying medicines, treatment duration, and expected benefit should be matched to the exact indication.
Procedure and practical considerations
Skin irritation beneath the arrays is common. The equipment and daily wear schedule can affect sleep, mobility, work, and quality of life. Eligibility may be affected by implanted devices or other conditions, and the treating team should explain array placement, adherence goals, imaging follow-up, and urgent symptoms.
