My mother has non-small cell lung cancer. I'm seeing a change in her skin. She has bumps appearing on a good portion of her face. Could that be from the cancer?

Skin eruptions in lung cancer patients have the same potential causes they would have in all other patients, plus a few more rare causes. Some patients treated with erlotinib (Tarceva) or gefitinib (Iressa) experience a rash much like acne. Just about all commonly used drugs can cause skin rashes with varying frequency, ranging from quite common to extremely rare.

Your mother's doctor will have the best idea of where to begin when determining if this skin change you have seen is related to her cancer, her cancer treatment or some other unrelated cause. It’s also possible that she might need to see a dermatologist if no cause is readily apparent.
