Tumor Embolization

IMAGE-GUIDED ONCOLOGY PROCEDURE

Tumor embolization is a minimally invasive, image-guided procedure used to reduce blood flow to selected tumors. It may be used to shrink or control tumors, reduce bleeding risk, support surgery, or deliver therapy directly through tumor-feeding vessels.

Quick Summary

Key takeaway: Tumor embolization blocks or reduces blood flow through vessels that supply a selected tumor.

Depending on the diagnosis and treatment goal, embolization may be used alone, before surgery, or with therapies such as chemotherapy or radiation-based microspheres. Planning depends on tumor type, location, blood supply, liver function when relevant, and overall health.

WHAT IS TUMOR EMBOLIZATION?

Tumor embolization is an image-guided procedure that treats selected tumors by targeting their blood supply. A thin catheter is guided through the arteries to vessels feeding the tumor, where embolic material is delivered to reduce or block flow.

Some tumor embolization procedures use particles alone, while others combine embolization with chemotherapy or radiation-based microspheres. The goal may be to slow tumor growth, reduce bleeding risk, relieve symptoms, or help prepare for another treatment.

Tumor embolization is not appropriate for every cancer or mass. The treatment plan depends on tumor type, location, blood supply, organ function, other treatment options, and overall medical condition.

Who May Be a Good Candidate

  • Selected tumor types
  • Tumor has blood supply
  • Bleeding risk concern
  • Surgery support needed
  • Image-guided option
A full evaluation helps determine whether tumor embolization is appropriate based on diagnosis, tumor blood supply, imaging findings, organ function, and treatment goals.

Conditions Treated

Tumor embolization may be considered for selected tumors or masses where controlling blood supply can support treatment goals.

Liver Tumors

Some liver tumors may be treated through tumor-feeding arteries using embolization-based therapy.

Hypervascular Tumors

Tumors with strong blood supply may be considered for flow reduction or pre-surgical planning.

Bleeding Tumors

Embolization may help control bleeding from selected tumors or abnormal vessels.

Pre-Surgical Tumor Care

Reducing blood flow before surgery may help lower bleeding risk in selected cases.

Benefits of Treatment

  • Targets tumor vessels
  • May reduce bleeding
  • Can support surgery
  • May slow tumor growth
  • Uses image guidance
Benefits depend on tumor type, blood supply, location, organ function, treatment goal, and follow-up care.

How the Procedure Works / What to Expect

Tumor embolization is performed with imaging guidance. A catheter is guided to tumor-feeding vessels, and embolic material or treatment-loaded particles are delivered to the target area.

Preparation Before Treatment

  • Imaging is reviewed
  • Lab work may be checked
  • Treatment goal is confirmed

During the Procedure

  • A catheter is placed
  • Tumor vessels are mapped
  • Blood flow is reduced

Recovery & Aftercare

  • Monitoring may continue
  • Symptoms are tracked
  • Follow-up imaging is needed

Risks / Considerations

  • Pain can occur
  • Fever may occur
  • Non-target flow is possible

Related Treatments / Alternatives

Depending on tumor type, location, and treatment goal, tumor embolization may be considered alongside other image-guided oncology treatments.

Embolization

A broader image-guided technique used to block targeted blood flow in selected conditions.

Tumor Ablation

An image-guided treatment that destroys selected tumor tissue using heat, cold, or other energy.

Frequently Asked Questions

Tumor embolization is a minimally invasive procedure that reduces or blocks blood flow to selected tumors through catheter-guided treatment.
Tumor embolization may be considered for selected tumors with a treatable blood supply, including some liver tumors and certain hypervascular masses.
Not always. Some embolization uses particles alone, while chemoembolization combines embolization with chemotherapy delivered near the tumor.
Yes. In selected cases, embolization may be used before surgery to reduce blood flow and lower bleeding risk.
Risks may include pain, fever, nausea, bleeding, infection, vessel injury, non-target embolization, liver injury when relevant, or need for additional care.
Planning depends on tumor type, location, blood supply, imaging findings, lab results, organ function, and the overall treatment plan.
