Wounds inside the mouth, known as mouth sores or oral mucositis, are most commonly linked to lung cancer treatments rather than antibiotics directly. They're a well-known side effect of chemotherapy and, less commonly, radiation therapy.

Here's why they happen:

- Chemotherapy targets rapidly dividing cells — but it doesn't only hit cancer cells. It also damages the healthy cells lining your mouth and throat
- Some targeted therapy medications used for lung cancer can also trigger mouth sores
- When chemotherapy weakens the immune system, it becomes easier for mouth infections to develop, which can worsen sores Specific lung cancer medications known to cause mouth sores include:

- Cisplatin, Etoposide, Fluorouracil, Methotrexate
- EGFR inhibitors like erlotinib, afatinib, osimertinib, and dacomitinib

It's really important to let your oncology team know about these sores as soon as they appear. Left unmanaged, they can make eating and drinking painful, potentially leading to dehydration and weight loss — which nobody needs on top of everything else!

Your care team can recommend treatments like prescription mouth rinses ("magic mouthwash"), pain relief, and simple diet adjustments to help keep things manageable.
