5. Hand & Finger Pain

Other warning signs of lung cancer that most people tend to ignore include fatigue and aches in your fingers. A disfiguring symptom called “tripe palms”, named so due to its appearance occurs in more than 35% of stomach cancer and 11% of lung cancer patients.

Here, the skin of the palm thicken and become whitish with prominent folds. Resulting from a change in bodily processes caused by cancer, it occurs because the palmar skin cells become hyper-stimulated. This results in buildups of thick, scaly, skin.
