For many patients diagnosed with a lung tumour, concerns about major surgery, recovery time, and overall health are common. While surgery remains an important treatment option, not all patients are suitable candidates for it.

Advances in medical technology have introduced less invasive alternatives. One such option is lung cryoablation, a targeted treatment that uses extreme cold to destroy tumour tissue while preserving as much healthy lung as possible.

Let’s understand how this approach works and who may benefit from it with Prof Zamrin, Cardiothoracic Surgeon at Sunway Medical Centre Velocity.

What Is Lung Cryoablation?

Lung cryoablation is a minimally invasive procedure used to treat certain lung tumours by freezing and destroying abnormal cells.

During the procedure, a specialised probe is inserted through the skin and guided precisely into the tumour using imaging such as CT scan. The probe then delivers extremely cold temperatures, forming an “ice ball” that destroys the tumour cells.

Because the treatment is targeted, surrounding healthy lung tissue can often be preserved.

When Is Lung Cryoablation Considered?

Lung cryoablation may be considered for patients who:

• Have small lung tumours

• Are not suitable for surgery due to age or other medical conditions

• Prefer a less invasive treatment option

• Have tumours that are difficult to remove surgically

• Require treatment for metastatic (spread) tumours to the lung

It is often part of a personalised treatment plan, discussed with a multidisciplinary medical team.

How the Procedure Is Performed

The procedure is typically performed under image guidance, such as CT scan, to ensure accuracy.

A small incision is made on the skin, and a thin probe is carefully inserted into the lung tumour. Once in position, controlled freezing cycles are applied to destroy the tumour cells.

Patients are usually monitored closely during and after the procedure. In many cases, hospital stay is shorter compared to traditional surgery.

Benefits of Lung Cryoablation

One of the main advantages of cryoablation is that it is less invasive than conventional lung surgery.

Because it does not require a large incision, patients may experience less pain and a quicker recovery. The procedure also allows for targeted treatment, helping preserve healthy lung tissue and maintain lung function.

For patients who are medically unfit for surgery or wish to avoid more extensive procedures, cryoablation offers a valuable alternative.

What Are the Risks?

As with any medical procedure, lung cryoablation carries some risks.

The most common complication is pneumothorax, where air leaks into the space around the lung, which may require temporary drainage. Other risks include bleeding, infection, or discomfort at the treatment site.

Your doctor will discuss these risks and determine whether the procedure is suitable based on your condition.

Recovery and Follow-Up

Recovery after cryoablation is generally faster compared to traditional surgery.

Most patients are able to resume normal activities within a shorter period, although follow-up imaging is required to monitor treatment response.

Regular follow-up is important to assess whether the tumour has been fully treated or if additional sessions are needed.

A Personalised Approach to Lung Cancer Care

Lung cryoablation is not a replacement for all forms of lung cancer treatment, but it plays an important role in selected patients.

Treatment decisions are based on tumour size, location, overall health, and patient preferences. A personalised approach ensures that each patient receives the most appropriate and effective care.

Taking the Next Step

A diagnosis of a lung tumour can feel overwhelming, especially when considering treatment options.

For some patients, minimally invasive treatments like cryoablation may offer a balance between effectiveness and recovery.
