"Man's Bizarre White Lines on Fingernails Reveal Cancer Drug Side Effects"
Originally Published 2 years ago — by Daily Mail
A cancer patient's concern over white lines on his fingernails led doctors to diagnose him with transverse leukonychia, a benign condition caused by chemotherapy drugs. While the patient's nail changes were harmless, marks, bruises, and lines on fingernails can sometimes indicate cancer or other health issues. Fingernail abnormalities can also be signs of heart problems, circulation issues, infections, or nutritional deficiencies. Regular self-examination of nails and maintaining good nail hygiene is recommended to monitor for any warning signs.
