Interventional Radiology Treatments for Cancer


If you have cancer, you may receive “image-guided treatments” known as interventional radiology. Today, more people survive cancer than ever before. This is partly because of innovations in imaging technology, including CT scans and MRIs. Modern imaging procedures let doctors catch cancer early. They also help doctors perform cancer treatments without the risks of surgery.

What is Interventional Radiology?

Interventional radiology is an important field within the specialty of radiology. Doctors who specialize in this field are interventional radiologists. They use sophisticated imaging technology and minimally invasive techniques to treat many diseases.

Most interventional radiology procedures use thin, hollow tubes (catheters). Imaging software helps the doctor guide the tube through blood vessels or other passageways to a specific place inside your body. Your doctor will pass tiny tools or treatments through the tube. These may include stents, balloons, laser energy, radioactive particles or medications.

Common Interventional Radiology Procedures

Interventional radiology procedures may be combined with other cancer treatments. These include radiation therapychemotherapy or cancer surgery. Our interventional radiology services include the following:


Ablation procedures use extreme heat or cold to destroy a tumor. Radiofrequency and microwave ablation procedures burn cancer cells. Cryotherapy freezes cancer cells.


Embolization procedures shrink a tumor or cut off its blood supply. One method inserts tiny beads into the blood vessels that feed the tumor. The beads block the blood vessel, suffocating the tumor. Sometimes beads containing chemotherapy or radioactive material are injected directly into the tumor. These procedures are called chemoembolization and radioembolization. They're usually used to treat liver cancer.

Kyphoplasty & Vertebroplasty

Kyphoplasty and vertebroplasty treat spine fractures caused by spinal tumors or other cancers. During vertebroplasty, your doctor injects bone cement into a collapsed vertebra. During kyphoplasty, your doctor inserts and inflates a small balloon in the vertebra. This creates space for bone cement. Kyphoplasty may be combined with radiofrequency ablation, to heat and destroy spinal tumors while simultaneously reinforcing the vertebrae.


Paracentesis treats a cancer complication called ascites. It occurs when fluid builds up inside your belly, causing abdominal swelling. Paracentesis uses a special needle to drain and collect the excess fluid. This helps reduce pain, improve kidney function and relieve shortness of breath.

Venous Access

Venous access procedures place special tubes under your skin. These tubes include ports, PICC lines and catheters. They let your caregivers draw blood or give medications from the same location, every time. This reduces the number of needle pricks you’ll receive over the course of your treatments.
