New Delhi: If you do not suffer from cancer, fever is a sign of defence that your body is fighting against infection. Usually, fever is not of much concern unless the temperature shoots up really high.
However, things are really different when you have cancer, and as these cells spread quickly, the immune system keeps getting weaker by the day. As you keep losing immunity, you are prone to frequent fever attacks, also known as Pyrexia.

However, common cancers like breast cancer, lung cancer, and bowel cancer are less likely to cause any fever. But if the tumour spreads to the liver, you may get slightly under the weather.

Health experts believe that it may also indicate that cancer is causing a blockage somewhere in the body.

What exactly causes fever in cancer?

Doctors say cancer fevers often rise and fall during the day, and sometimes they peak at the same time.

A progressing tumour, according to doctors causes infections that produce pyrogens, that enter the body through outside sources like bacteria, viruses, fungi, drugs, and toxins. The cells of your immune system like cytokines can also build pyrogens.

Pyrogens also hinder the functioning of the hypothalamus, a part of the brain that controls body temperature. The hypothalamus is connected to various other areas of the body like the nervous system, endocrine system, skin, muscles, and sweat glands to help boost processes that take place without us thinking about them, such as blood pressure, breathing, heartbeat, regulation of body fluids, salt concentration and body temperature.

When you are undergoing cancer treatment, a fever may destroy white blood cells and weaken your immune system, making you more vulnerable to inflammation and infection.

Even prescribed medications like steroids and morphine can cause fever.

How to cope with a fever?

According to health experts, if you feel your body temperature is going high (normal body temperature is 98.6° F (36° C), take the following steps before reaching out to the doctor:

  • Do not take aspirin, ibuprofen, or any fever-reducing analgesic medicine without consulting the doctor.
  • Drink a lot of water. Avoid drinking coffee, tea, or any caffeinated product and alcohol.
  • Take adequate rest
  • Put a cold cloth or ice bag on your head or take bath with cold water to reduce temperature.
  • Eat nutritious food which includes fruits and vegetables that have vitamins and antioxidants.
