Diagnosis and Treatment of Cancer through Imaging Guided Biopsy

Introduction

Cancer is a leading cause of mortality worldwide, with millions of people diagnosed every year. However, with the advancement of medical technology, there are various ways to diagnose and treat cancer. One such method is imaging-guided biopsy, which allows doctors to collect tissue samples for diagnosis and treatment. This article will discuss the procedure of diagnosis of cancer through imaging-guided biopsy, its preparation, and various treatment options.

Understanding Imaging-Guided Biopsy for Diagnosis of Cancer

Imaging-guided biopsy is a medical procedure in which doctors use imaging technology, such as ultrasound, MRI, CT scan, or X-rays, to locate the tumor and collect tissue samples. The procedure is minimally invasive, and patients can return home on the same day. However, before the procedure, patients need to follow specific guidelines and prepare themselves for the biopsy.

How is the Preparation for the Procedure?

Before the procedure, patients need to avoid eating and drinking anything for a few hours. The doctor will give specific instructions on how to prepare for the procedure, which includes avoiding blood-thinning medications and informing the doctor about any allergies or medical conditions.

How is the Port Placed?

A port is a small device that is placed under the skin and connects to a vein. It allows doctors to inject medication, take blood samples, or perform the biopsy without repeatedly inserting needles. The placement of the port is done under local anesthesia and can be done a few days before the biopsy.

Local Treatments in Liver Cancers

Liver cancer is one of the most common types of cancer that can be treated using imaging-guided biopsy. Local treatments such as Radiofrequency ablation (RFA), Microwave ablation (MWA), and Cryoablation can be used to destroy the cancerous cells in the liver. These procedures are done under imaging guidance, and the recovery period is minimal.

Other Cancers Where Ablation Therapy Is Used

Apart from liver cancer, ablation therapy can also be used to treat tumors in the lungs, kidneys, and bones. In lung cancer, the procedure is known as Radiofrequency Ablation (RFA), which uses radio waves to heat and destroy the tumor. In bone cancer, Cryoablation is used to freeze and destroy the cancerous cells.

Chemoembolization

Chemoembolization is a minimally invasive procedure that is used to treat liver cancer. The procedure involves injecting chemotherapy drugs directly into the tumor and blocking the blood supply to the tumor, which starves the cancer cells of oxygen and nutrients, leading to their death. The recovery time for chemoembolization is minimal, and the patient can return home on the same day.

Radioembolization

Radioembolization is a newer form of treatment that is used for patients with liver cancer. It involves injecting tiny radioactive particles into the blood vessels that feed the tumor. The radiation kills the cancerous cells while minimizing the damage to healthy tissues. This procedure is minimally invasive and has a shorter recovery period than traditional cancer treatments.

Other Supportive Interventional Methods in Oncology

Apart from the above-mentioned procedures, there are other supportive interventional methods in oncology that can be used to treat cancer. These include Percutaneous Drainage, Stenting, Embolization, and Vertebroplasty. These procedures are done under imaging guidance, and the recovery period is minimal.

Conclusion

Imaging-guided biopsy is a minimally invasive and effective method of diagnosing and treating cancer. With the help of imaging technology, doctors can locate the tumor and perform biopsy procedures that help in the diagnosis and treatment of cancer. Furthermore, the local treatments such as ablation therapy, chemoembolization, radioembolization, and other supportive interventional methods in oncology offer effective and minimally invasive treatment options with minimal recovery time. Therefore, it is crucial to consult with a doctor and discuss the available treatment options for the best possible outcome.
