What are The Causes of Cancer Hives?

Several things can cause cancer hives. Cancer is a disease in which certain types of abnormal cells uncontrollably grow. They can spread to other parts of the body and eventually kill you. Common causes of cancer hives include Hepatitis B or C, Prostate Cancer, and Crohn’s Disease. There are a lot of treatments for cancer hives but you need to find the right one including medical, surgical, or radiation treatment.

Cancer Hives are red, itchy welts that often appear under the armpits or the breasts. It is a known fact that cancer hives can either be localized or can grow and spread to other parts of the body, metastasizing until they reach a fatal organ. Once they have reached the liver or spleen, death is inevitable. Luckily, cancer hives aren’t that common.

The Causes of Cancer Hives

There are many different causes of cancer hives, including:

  • A reaction to a medication. Your doctor may prescribe medications to treat your cancer that can cause hives. These medications include interferon and interleukin-2.
  • A reaction to biological therapy. Some cancer patients receive biologics, which are proteins that target cancer cells. These proteins can cause hives in some people.
  • A reaction to radiation therapy. Radiation therapy uses high-energy waves to destroy cancer cells. It may also damage the cells around them, which can trigger hives in some people.
  • Cancer hives are caused by the body’s response to cancerous growth in the body. The body can sometimes release histamine as part of this response, which causes hives to form on the skin.

The most common cause of cancer hives is cancer itself, but there are some other causes as well. These include:

Allergic reactions

An allergic reaction can cause histamine levels in the blood to rise, which can lead to hives. Allergies can be caused by food or medications and may also be seasonal for some people.


Certain medications such as antibiotics and antidepressants may cause an increase in histamine levels in your blood, which could lead to hives developing on your skin. This can also happen if you stop taking these medications suddenly or if they interact with other drugs that you may be taking at the same time.

Food allergies

Food allergies can cause an allergic reaction when something is eaten or drunk by someone who has a sensitivity or allergy to it. This can lead to hives forming on their skin or around their mouth area if they have suffered anaphylaxis (a severe reaction) after ingesting something that triggers a response in their body.
