Cancer Treatment
Interventional radiologists can deliver treatments for cancer directly to the cancer without significant side effects or damage to nearby normal tissue. There are two main methods by which interventional radiologists can treat cancer. The first is to use the vascular system to deliver chemotherapy medicine directly to the cancer's vascular supply. This limits damage and toxicity to the rest of the body while delivering the highest dose of the chemotherapy to the cancer. The second method interventional radiologists use to treat cancer is to "cook" or "freeze" the cancer by placing a small, energy-delivering needle directly into the cancer that heats or freezes the cancer without significant damage to nearby normal tissue. These needles are placed using ultrasound, X-ray or CT scan technology, which allows very precise placement.
Since these techniques are delivered at the cancer specifically, patients have fewer overall side effects making this especially useful in patients with other significant medical problems. According to the National Cancer Institute, "targeted cancer therapies will give doctors a better way to tailor cancer treatment."
