Being diagnosed with stage 1 lung cancer can feel frightening, but the good news is that early detection often means more effective treatment options. One of the most advanced and minimally invasive procedures available today is Video-Assisted Thoracoscopic Surgery (VATS).
VATS is rapidly becoming the standard of care for patients with early-stage lung cancer due to its precision, quicker recovery time, and reduced post-surgical complications. In this blog, we’ll explore what VATS is, how it works, its benefits, potential risks, and why it’s considered a breakthrough for stage 1 lung cancer patients.
What Is Stage 1 Lung Cancer?
Lung cancer is classified into stages based on how far the disease has spread. Stage 1 lung cancer is considered early-stage, meaning the tumor is small and has not spread to lymph nodes or other parts of the body.
Stage 1 is further divided into:
- Stage 1A: Tumor is 3 cm or smaller.
- Stage 1B: Tumor is larger than 3 cm but smaller than 4 cm, or it has grown into nearby structures like the visceral pleura (lung covering), but without lymph node involvement.
Because the cancer is still localized, surgical removal is often the best and most effective treatment option — and this is where VATS plays a major role.

What Is Video-Assisted Thoracoscopic Surgery (VATS)?
Video-Assisted Thoracoscopic Surgery (VATS) is a minimally invasive surgical technique used to operate inside the chest. Instead of making one large incision, as in traditional thoracotomy, surgeons use two to four small cuts to insert a tiny camera and special surgical tools.
How VATS Works:
- Small incisions (typically 1–2 cm) are made between the ribs.
- A thoracoscope (a camera on a thin tube) is inserted, sending real-time images to a video monitor.
- The surgeon uses these visuals to guide instruments and remove the tumor, a section of lung, or lymph nodes.
- Once complete, the instruments are removed, and the incisions are closed.
Why Is VATS Used for Stage 1 Lung Cancer?
Since stage 1 lung cancer is localized and has not spread, it’s ideal for surgical treatment. The goal is to completely remove the tumor and any potentially affected tissue before the cancer progresses.
VATS is often used for procedures such as:
- Lobectomy – removal of one lung lobe (standard surgery for early lung cancer)
- Segmentectomy – removal of a lung segment
- Wedge resection – removal of a small, wedge-shaped portion of the lung containing the tumor
Benefits of VATS Over Traditional Surgery
Compared to traditional open thoracic surgery, VATS offers several significant advantages:
1. Minimally Invasive
- VATS avoids the need for large incisions or rib spreading.
- Small cuts result in less trauma to the chest wall.
2. Faster Recovery
- Patients usually spend less time in the hospital (2–5 days).
- Recovery at home is quicker, often within 4–6 weeks.
3. Less Pain
- Smaller incisions mean reduced postoperative pain.
- Lower dependence on strong painkillers.
4. Lower Risk of Complications
- Reduced risk of infection and bleeding.
- Lower chances of lung function issues or respiratory complications.
5. Comparable Long-Term Results
- Survival rates with VATS are similar, if not better, than those of traditional surgery in early-stage lung cancer cases.
Who Is a Candidate for VATS?
VATS is an excellent option for many patients with stage 1 non-small cell lung cancer (NSCLC). However, it’s not suitable for everyone. Eligibility depends on:
Ideal Candidates:
- Tumor is small and well-located
- No involvement of nearby lymph nodes
- Good overall health and lung function
- No prior extensive chest surgeries
VATS May Not Be Suitable If:
- Tumor is difficult to access via minimally invasive tools
- Cancer has spread to lymph nodes or surrounding structures
- Patient has severe lung or heart disease
- There is significant scar tissue in the chest
In such cases, open surgery or alternative treatments like radiation therapy may be considered.
What Happens Before, During, and After the Procedure?
Before Surgery:
- Preoperative tests: Imaging (CT, PET), pulmonary function tests, blood work.
- Consultations: Anesthesiologist and surgical team evaluations.
- Preparation: Instructions may include fasting, stopping certain medications, and quitting smoking.
During Surgery:
- The patient is placed under general anesthesia.
- Surgeon performs the procedure using the thoracoscope and small instruments.
- Duration: Usually 2 to 3 hours.
- A chest tube is placed post-operation to drain fluid and help the lung re-expand.
After Surgery:
- Monitoring in the recovery room, followed by a hospital stay.
- Pain is managed with medications.
- Breathing exercises and walking are encouraged to promote recovery.
- Chest tube is usually removed after a few days.
- Follow-up appointments to monitor healing and review pathology results.
Risks and Possible Complications
While VATS is considered safe, as with any surgery, there are potential risks:
Common Risks Include:
- Bleeding
- Infection
- Air leak from the lung
- Blood clots
- Pain or numbness around the incision site
Rare but Serious Risks:
- Reaction to anesthesia
- Need to convert to open surgery mid-procedure
- Damage to surrounding organs
Choosing an experienced thoracic surgeon significantly reduces the risk of complications.
How Effective Is VATS for Stage 1 Lung Cancer?
Numerous studies have shown that VATS is highly effective for early-stage lung cancer, offering:
- Excellent survival rates
- Low recurrence rates when the tumor is fully removed
- Better postoperative quality of life
- Comparable (or better) outcomes than open surgery
In stage 1 lung cancer, VATS lobectomy is considered the gold standard when surgery is indicated.
Alternatives to VATS
While VATS is often the best surgical choice, some patients may not be surgical candidates. Alternative treatments include:
1. Stereotactic Body Radiation Therapy (SBRT):
- Delivers high-dose radiation to the tumor
- Used for patients who cannot undergo surgery
2. Radiofrequency Ablation (RFA):
- Uses heat to destroy cancer cells
- Mostly for small tumors or patients who are not surgical candidates
These options can be effective, but surgical removal remains the preferred treatment for eligible patients with stage 1 lung cancer.
The Future of Minimally Invasive Lung Surgery
Surgical techniques continue to evolve. Some of the emerging advancements include:
Robotic-Assisted Thoracic Surgery (RATS):
- Uses robotic arms and 3D imaging for greater precision
- Allows more complex procedures to be performed minimally invasively
Enhanced Recovery After Surgery (ERAS) Protocols:
- Focus on pain control, early mobility, and nutrition
- Improve recovery outcomes following VATS
As technology and training improve, more patients with early-stage lung cancer will benefit from less invasive, highly effective treatments like VATS.
Conclusion
Video-Assisted Thoracoscopic Surgery (VATS) is a transformative option for patients with stage 1 lung cancer. It combines the effectiveness of traditional surgery with the benefits of a minimally invasive approach. With smaller incisions, reduced pain, quicker recovery, and strong long-term outcomes, VATS has become a leading choice for early lung cancer treatment, especially when performed by experienced thoracic surgeons like Dr Harsh Vardhan Puri.
