Introduction to IO
Interventional oncology (IO) is a specialty that uses minimally invasive procedures done through small cuts in the skin to treat cancer. Doctors use imaging tools like ultrasound, CT scans, or MRIs to guide the treatments, so they can target tumours accurately and avoid damage to healthy tissue.
One type of IO treatment uses a thin needle with an active tip placed through the skin into the tumour. Microwave energy from the needle is used to destroy the cancer cells. Another type of treatment involves sending radiation or chemotherapy directly into the tumour’s blood supply.
Interventional oncology can be a good option for patients who cannot have traditional surgery or want to explore other treatment options.
Interventional oncology can help treat liver cancer, kidney cancer, and lung cancer, as well as cancer that has spread from other parts of the body (metastasised) to the liver, lungs and the bones. Your treatment plan will depend on your health and the type of cancer you have.
❕Always talk to your doctor or an interventional oncologist if you have any questions or concerns.
Interventional oncology treatments have many advantages:
🔹Minimally invasive: IO procedures usually use only small incisions, which leads to less pain and a faster recovery compared to traditional surgery.
🔹Precise: Doctors use advanced imaging to accurately target tumours while protecting healthy tissue.
🔹Shorter hospital stay: Many IO treatments are done as outpatient procedures, so you can go home the same day or after a short recovery.
🔹Effective for certain cancers: IO works especially well for liver, kidney, lung, and some other types of cancer.
Even though IO procedures are minimally invasive, there are some risks, including:
🔸Infection at the needle site
🔸Bleeding or hematoma (a collection of blood under the skin)
🔸Injury to nearby organs or tissues
🔸Allergic reaction to contrast dye or medications
Your interventional oncologist will explain these risks before the procedure and take steps to keep you as safe as possible.
