Skin changes can reveal hidden health issues. A condition called acanthosis nigricans—where skin becomes darker, thicker, and velvety—can sometimes signal cancer.
Though more often linked to obesity, diabetes, or hormonal imbalances, it may rarely indicate cancers like stomach, liver, or lymphoma. Areas to watch include:
-
Neck – Persistent dark, thick patches that resemble dirt.
-
Armpits – Sudden darkening with a velvety feel.
-
Groin – Rapid changes in color or texture.
-
Elbows/Knees – Unusual thickening and deepening of shade.
-
Around Lips/Eyes – Dark patches that resist treatment.
If these changes appear suddenly or are paired with fatigue, weight loss, or digestive issues, see a doctor promptly. Early detection saves lives.
