Chemotherapy drugs are cytotoxic. The causes of skin itching following chemotherapy may include dry skin, drug allergy, and immune system disturbances. Dry skin is often triggered by the toxic side effects of chemotherapy. Mild itching can be gradually relieved by washing with lukewarm water and avoiding exposure to direct sunlight.

Drug allergies occur because medications used during chemotherapy to achieve anti-tumor effects may lead to allergic reactions in the body. Such reactions could also stem from immune system dysregulation, resulting in autoimmune-like allergic responses. Patients can visit a local hospital for evaluation and, under a doctor's guidance, take antiallergic medications such as paclitaxel.

In addition, slowed skin metabolism may also contribute to itching. During treatment, patients should maintain a positive mindset, pay attention to skin care, and actively manage their condition.
