Post-Surgery Complications to Watch For After NSCLC Surgery

After lung cancer surgery, it's important to know what side effects and complications can occur so you can report them to your healthcare team promptly. According to the NCCN Guidelines for Patients: Non-Small Cell Lung Cancer, here are the key complications to monitor:

Common Side Effects After Surgery

Pain and Swelling

  • Pain can be intense immediately after lung surgery, but typically fades over weeks
  • Swelling near the surgical area is normal and usually resolves gradually
  • Numbness near the surgical site may persist longer-term

Infection

  • Watch for signs of infection, which can develop after any surgery
  • Pneumonia (lung infection) is a possible complication—report fever, cough, or difficulty breathing to your doctor immediately

Collapsed Lung (Pneumothorax)

  • This occurs when air leaks into the space around your lung, causing it to collapse
  • Symptoms include sudden shortness of breath, chest pain, or difficulty breathing
  • This requires immediate medical attention

What to Report to Your Care Team

According to NCCN Guidelines, you should let your treatment team know about any new or worsening symptoms, including:

  • Increased pain not controlled by medication
  • Fever or signs of infection
  • Persistent cough or coughing up blood
  • Shortness of breath or difficulty breathing
  • Chest pain or pressure
  • Swelling that worsens instead of improves
  • Drainage from the surgical wound
  • Any unusual symptoms

Important Context

The specific complications you might experience depend on several factors your surgical team will discuss with you:

  • The type of surgery you had (lobectomy, segmentectomy, wedge resection, or pneumonectomy)
  • Whether minimally invasive surgery (VATS or robotic-assisted) or open surgery was used
  • Your overall health and lung function before surgery
  • Whether you received neoadjuvant therapy (treatment before surgery)

Questions to Ask Your Surgical Team

  1. What type of surgery am I having, and what specific complications should I watch for?
  2. What pain management options will be available after surgery?
  3. How long should I expect pain and swelling to last?
  4. What symptoms require immediate emergency care versus a phone call to your office?
  5. When can I resume normal activities, and what restrictions will I have?
  6. Will I need pulmonary rehabilitation or breathing exercises after surgery?
