Liver cancer is a common type of tumor in the digestive system in China, and patients with early-stage liver cancer generally do not experience significant changes in their hair. This is because the tumors in early-stage liver cancer patients are relatively small, and the treatment often involves surgical removal, which does not require chemotherapy or other anti-tumor treatments, so the impact on the patient's hair is minimal. As the disease progresses, some patients may need to undergo chemotherapy or other anti-tumor treatments, which can lead to hair loss or changes in hair color. However, hair changes after chemotherapy in liver cancer patients are generally reversible, and hair can regrow after the end of chemotherapy. Changes in hair color, on the other hand, are generally caused by pigment deposition induced by some chemotherapy drugs.
