Using catheters or needles, physicians can deliver radiation or chemotherapy drugs directly into tumors, sparing healthy, surrounding tissue.
Interventional treatments include:
- Chemo-embolization, in which chemotherapy drugs are injected into an artery supplying a tumor with blood
- Tumor ablation, in which cold, heat or radiofrequency waves are used to destroy tumor cells
Treatments are less invasive and typically involve less pain and quicker recovery. Many can be performed on an outpatient basis or with a short hospital stay.
