Do cancer cause fever?

My uncle has been having on-and-off fever for some time now, even without any apparent infection. He is worried about what it could be, and I read something online about cancer causing fever. Is this true?

My dad had a continuous low-grade fever when he was diagnosed with kidney cancer. It is often one of the first signs of the body fighting something big. If the fever is not going away with normal medicine, get proper blood tests done.

Yes, cancer can cause fever, especially if it is lymphoma or leukemia, or if there is an infection due to low immunity. My uncle had persistent mild fever which we ignored initially, leading to complications later. Please don't ignore unexplained fever and consult a doctor immediately.

Haan, cancer ki wajah se fever aa sakta hai, particularly night sweats ke sath na. Sometimes treatments like chemotherapy also cause fever. Isko halka mat lo, please doctor se consult karke checkup karvao jald se jald.

Our bodies are so complex, even a small imbalance can cause a fever. But if it is persistent, don't sit at home trying to guess the reason or getting scared by searching online. Just go to a good hospital and let the doctors do their job.

Unexplained fever is a warning sign that the body is under stress, and it can indeed be linked to cancer. If you are experiencing this, avoid strenuous workouts or heavy walking. Rest completely and let a doctor evaluate the symptoms thoroughly.

Fever can be a symptom because of how the illness affects the immune system. While eating fresh, nutrient-rich food and staying hydrated helps support the body, it is absolutely essential to seek professional medical advice to find the real root cause of the fever.

During my cancer treatment, fever was a major red flag for infections. We were told to monitor temperature every few hours and report anything above 100.4 F to the oncologist immediately. Keep a digital thermometer handy and maintain a log.
