A sudden wet and productive cough can feel alarming, especially with lung cancer. There are several possible reasons this might be happening.
A wet cough can be linked to:
- The cancer itself — lung cancer can cause increased mucus or phlegm production in the airways
- Treatment side effects — chemotherapy, radiation, or immunotherapy can irritate the throat and lungs, triggering a wetter cough
- Excess mucus buildup — sometimes the lungs produce more watery phlegm, a condition called bronchorrhea
- A respiratory infection — an infection in your airways can cause a sudden increase in mucus One important thing to watch — if the phlegm appears pink or red, contact your oncologist right away, as coughing up blood can be a sign of a complication that needs prompt attention.
A MyLungCancerTeam member shared that their cough varied between loose and dry depending on where they were in their treatment cycle, so changes in cough type are not uncommon.
It's really worth flagging this new development with your care team as soon as possible so they can identify the cause and help manage it.
