Yellowing nails may be a sign of liver cancer, but it depends on the case and cannot be generalized. Some abnormal manifestations of the body may be signs of some diseases, such as changes in nail color, which can indicate different pathologies. Normal nails are light red, tough, not easy to break, and the nail surface is smooth. However, when suffering from liver and gallbladder diseases, such as hepatitis, liver cancer, cholecystitis, etc., abnormal bile circulation may cause jaundice, and the nails, skin and conjunctiva may be yellow stained and appear yellow, and the yellow color may gradually deepen as the disease progresses, and the nails are rough and lusterless. If the above situation occurs, it is recommended to go to the liver department of the hospital as soon as possible to clarify the cause and then actively take treatment to avoid delaying the disease. If your nails turn yellow, especially when accompanied by symptoms such as gastrointestinal discomfort and abdominal pain, you should not be careless and need to seek medical attention promptly. You can usually take in foods rich in vitamin C, such as kiwi, etc.
