It may be caused by taking drugs, such as frequent contact with drugs such as rizosin, onion forest, insect repellent, etc., which can also cause yellow nails. It has also been reported that taking anti-inflammatory and analgesic drugs Blaximine and methotrexate can also cause yellow nails.

What should I do about this phenomenon? After the patient stops taking the medicine, his nails will return to normal for a while, so don't worry too much. Ensure daily work and rest, take medicine on time, and don't affect sleep and mood because of anxiety.

There is no basis for saying that the thickening and yellowing of toenails is cancer.

The thickening and yellowing of toenails are mostly caused by the above reasons, and have nothing to do with cancer. Don't believe this groundless statement and cause unnecessary panic. At present, if the patient has cancer, the toenails may appear black, accompanied by pain, bleeding, irregular nail edges and other abnormal phenomena. This phenomenon requires vigilance and timely medical treatment.
