Are dizziness or changes in vision signs of lung cancer?

Dizziness or changes in vision would only be symptoms of a very advanced lung cancer. These also could be symptoms of any advanced malignancy (or could potentially signify spread of cancer to the brain—not typical of lung cancer).

Not typically. In rare cases in which there has been spread (or metastases) of the cancer to the brain, certain affected areas can lead to dizziness or visual changes. In other rare situations, lung cancer can change the movement of blood and air in the lung. If the patient already has impaired lung function such as emphysema, then this could lead to lower oxygen levels in the blood which might also manifest as feeling faint or dizzy. Bottom line, however, is that these symptoms are not usually associated with lung cancer.

Dizziness and changes in vision are not commonly associated with lung cancer. If your symptoms are out of the ordinary or persist, talk to your doctor.
