Fever and night sweats
Fever (when the temperature of the body is above 38°C or 100.4°F) is normally caused by an infection, but there may be other less common reasons, including lymphoma. In the case of blood cancer, fevers are usually mild and go away quickly.
Lymphoma can also cause drenching, or night sweats, that can make pajamas and bedsheets soaking wet. Although they are called “night” sweats, they can also take place in the daytime. Night sweats can happen in any type of lymphoma, but the exact reason is unknown. Some believe that this is the way our body reacts to chemicals produced by lymphoma cells. Others think that this symptom is a natural response to fever, when the body’s temperature gets higher than normal, and the body tries to cool down through sweating.
Other possible reasons for night sweats include infection, anxiety, menopause, an overactive thyroid gland and some medicine. Be sure to see a doctor if you have night sweats together with other symptoms such as fever or unexplained weight loss. [8]
