Can Keytruda cause ground glass nodules on the lungs? This is a really important question to explore.
Keytruda (pembrolizumab) is an immunotherapy that works by helping your immune system attack cancer cells. One known side effect is pneumonitis — inflammation of the lung tissue — which can show up on scans as ground-glass opacities (hazy, frosted-glass-looking areas).
These ground-glass changes are not the same as nodules, but they can look similar on imaging. They are worth taking seriously. A MyLungCancerTeam member shared their experience developing pneumonitis as a reaction to their lung cancer medication, which led to hospitalization and a prolonged recovery involving steroids and antibiotics.
If you notice new or worsening symptoms like:
- Shortness of breath
- A new or worsening cough
- Chest pain or discomfort
- Fever
...it's really important to contact your oncology team right away. Pneumonitis from immunotherapy can be serious but is manageable when caught early. Don't wait on this one — reach out to your care team promptly.
