2. Fever
A fever is a common symptom of many illnesses. However, fevers associated with cancer often occur after it has spread to other parts of the body. Some other common signs that a fever may be associated with cancer are if the onset of a fever happens mostly at night, you experience night sweats, and you don’t have any other signs of infection. Generally, all cancer patients will have a fever at some point as the tumor affects the immune system.
