Cancer treatment has come a long way. For many patients, the word “cancer” still brings images of major surgery, long hospital stays, and harsh side effects. But modern medicine offers another path. Interventional oncology uses image-guided, minimally invasive procedures to treat cancer directly. These treatments target tumors with precision, spare healthy tissue, and often allow patients to recover faster.
At Southern Vascular, interventional radiologists use advanced technology to deliver cancer therapy through tiny incisions, sometimes no larger than a pencil tip. This guide explains what interventional oncology is, how it works, and why it matters for patients in Mississippi, Tennessee, and Kentucky.
What Is Interventional Oncology?
Interventional oncology is a subspecialty of interventional radiology. It focuses on delivering cancer treatment using needles, catheters, and other small instruments guided by real-time imaging like CT, ultrasound, or fluoroscopy.
Unlike traditional surgery, interventional oncology does not require large cuts or general anesthesia in many cases. Instead, the interventional radiologist accesses the tumor through a small nick in the skin. The result: less pain, fewer complications, and shorter recovery times.
Southern Vascular’s interventional oncology services are designed for patients who:
- Have tumors that are hard to reach with conventional surgery
- Need symptom relief when cancer has spread
- Want treatment options with less downtime
- Cannot tolerate major surgery due to other health conditions
How Interventional Oncology Works: The Interventional Radiology Advantage
Interventional radiologists are physicians specially trained in both diagnostic imaging and minimally invasive procedures. At Southern Vascular, they use this expertise to target cancer cells while leaving healthy tissue alone.
The process typically follows these steps:
- Imaging guidance – The doctor uses CT, ultrasound, or X‑ray to see the tumor clearly.
- Small incision – A tiny cut is made, often smaller than a fingernail.
- Precision treatment – A catheter or needle is guided to the tumor.
- Delivery of therapy – The treatment (heat, cold, radiation, or medication) is applied directly.
- Recovery – Most patients go home the same day or after a short observation.
This approach is a true alternative to open surgery. It also works alongside chemotherapy, radiation, or immunotherapy.
Common Minimally Invasive Cancer Treatments Offered in Interventional Oncology
Southern Vascular provides several interventional oncology procedures. Each one targets cancer in a different way.
1. Tumor Ablation (Heat and Cold)
Ablation destroys tumors by changing their temperature. Two common types are:
- Radiofrequency ablation (RFA) – Uses heat from radio waves to burn cancer cells.
- Cryoablation – Uses extreme cold to freeze and kill the tumor.
These techniques work well for small tumors in the liver, kidney, lung, or bone. The dead tissue stays in place and the body naturally removes it over time.
2. Chemoembolization (Transarterial Chemoembolization or TACE)
This treatment delivers chemotherapy directly to a liver tumor while cutting off its blood supply. A tiny catheter is threaded into the artery that feeds the tumor. Then, high-dose chemo is injected, followed by small particles that block the vessel. The cancer cells receive a powerful dose of medicine, but the rest of the body gets very little.
TACE is a standard option for patients with liver cancer or tumors that have spread to the liver.
3. Radioembolization (Y-90)
Radioembolization uses tiny glass or resin beads filled with radioactive yttrium-90. These beads are injected into the artery supplying a liver tumor. The beads lodge in the small vessels around the cancer and deliver radiation directly to the tumor for days or weeks. Healthy liver tissue is largely spared.
Cancer that spreads to bones can cause severe, hard-to-control pain. Interventional oncology offers targeted pain relief.
- Nerve blocks – Medication is injected around specific nerves to stop pain signals.
- Cryoanalgesia – A small probe freezes a nerve temporarily, providing weeks or months of relief.
- Kyphoplasty – For spinal tumors that cause fractures, a balloon is inserted into the collapsed vertebra, inflated, and filled with bone cement. This stabilizes the bone and reduces pain dramatically.
These procedures help patients reduce their need for opioid painkillers and improve quality of life.
5. Catheter-Directed Therapies for Other Cancers
Interventional radiologists can also place ports, drains, or stents to manage cancer complications. For example:
- Bile duct stents for obstructive jaundice
- Feeding tubes for patients who cannot eat
- Drains for fluid buildup in the chest or abdomen
Who Is a Candidate for Interventional Oncology?
Many patients can benefit from these treatments. The best candidates include those with:
- Primary liver cancer (hepatocellular carcinoma)
- Colorectal cancer that has spread to the liver
- Kidney tumors
- Lung tumors
- Bone metastases causing pain
- Neuroendocrine tumors
Even patients who have been told they are not candidates for surgery may qualify for interventional oncology. The team at Southern Vascular evaluates each case individually.
Benefits of Minimally Invasive Cancer Treatment
Compared to traditional surgery, interventional oncology offers clear advantages:
- Smaller incisions – Less scarring, lower infection risk
- Less pain – Often requires only local anesthesia or mild sedation
- Shorter hospital stay – Many procedures are outpatient
- Faster recovery – Return to daily activities in days, not weeks
- Repeatable – Can be performed multiple times if new tumors appear
- Preserves healthy tissue – Targets only the tumor
- Lower risk for frail patients – Safer for elderly or those with other illnesses
What to Expect During an Interventional Oncology Procedure
Understanding the process can ease anxiety. Here is what a typical experience looks like at Southern Vascular.
Before the procedure:
You will have imaging (CT, MRI, or ultrasound) to map the tumor. Your doctor explains the steps and answers questions. You may need to stop certain medications or avoid food for a few hours.
During the procedure:
You lie on a table. The skin over the treatment area is numbed. The interventional radiologist makes a tiny incision and guides the catheter or probe using live imaging. You might feel pressure but rarely sharp pain. Most procedures take one to two hours.
After the procedure:
You rest in a recovery area. Some patients go home the same day. Others stay overnight for observation. Your care team gives you specific instructions about activity, wound care, and follow-up.
Honoring Oncology Nursing Month: The Role of Oncology Nurses in Your Care
May is Oncology Nursing Month. This is a time to recognize the dedicated nurses who support cancer patients every day. At Southern Vascular and in cancer centers across Mississippi, Tennessee, and Kentucky, oncology nurses do far more than take vitals.
They:
- Help you understand complex procedures and what to expect
- Manage pain and side effects before, during, and after treatment
- Coordinate care between your interventional radiologist, oncologist, and primary doctor
- Provide emotional support for you and your family
- Teach you how to care for yourself at home
Oncology nurses are often the consistent presence in a patient’s cancer journey. They answer questions at 2 a.m., hold hands during difficult moments, and celebrate small victories. Southern Vascular thanks every oncology nurse for their skill, compassion, and commitment.
Why Interventional Oncology Matters for Mississippi, Tennessee, and Kentucky
The region Southern Vascular serves faces high rates of cancer risk factors, including smoking, diabetes, and obesity. Access to specialty care can be limited, especially in rural areas like the Mississippi Delta, West Tennessee, and Western Kentucky.
Interventional oncology offers a practical solution. Many procedures are outpatient, so patients do not need to travel far or stay in a hospital for weeks. Treatments are less physically demanding, which matters for older adults or those with other chronic diseases.
Southern Vascular operates clinics in Southaven, MS; Olive Branch, MS; Memphis, TN; Union City, TN; and Fulton, KY. This local presence means patients can receive advanced cancer therapy close to home.
