What Cancer Can Cause Itchy Skin?

Itchy skin, also known as pruritus, can be associated with various types of cancer. Here are some cancers that can cause itchy skin:

  1. Lymphoma: Hodgkin lymphoma and certain types of non-Hodgkin lymphoma, such as cutaneous T-cell lymphoma (CTCL), can present with persistent itching and skin rashes. The itching is often more pronounced after a warm shower or during periods of increased body temperature.
  2. Leukemia: Chronic lymphocytic leukemia (CLL) and some other types of leukemia can cause itchy skin. The exact mechanism is not fully understood, but it may be related to the release of chemicals by cancer cells or the immune system response.
  3. Liver cancer: Itchy skin can be a symptom of hepatocellular carcinoma (primary liver cancer) or intrahepatic cholangiocarcinoma (bile duct cancer). It is believed to be associated with the buildup of bile salts in the bloodstream due to impaired liver function.
  4. Pancreatic cancer: Itchy skin can occur in pancreatic cancer due to the release of substances called histamines, which can stimulate nerve endings and cause itching.
  5. Gallbladder cancer: Itchy skin may be a result of bile duct blockage caused by gallbladder cancer. The accumulation of bile salts in the bloodstream can lead to itching.
  6. Skin cancer: Melanoma, a type of skin cancer, can occasionally cause itching or a pruritic rash. However, it’s important to note that most cases of skin itching are not caused by melanoma or other skin cancers.

Itchy skin can also be associated with other non-cancerous conditions or side effects of cancer treatment. If you are experiencing persistent itching or any other concerning symptoms, it is important to consult with a healthcare professional for a proper evaluation and diagnosis. They can help determine the underlying cause and provide appropriate management.
