Cancer
Night sweat is an early symptom of some cancers. Asides from it being a symptom, it can also be a symptom of some cancer treatments. Example of some common types of cancer associated with night sweat include lymphoma, leukemia, breast cancer in women, and prostate cancer in men, and some other undiagnosed cancer that can cause night sweat. In attempt to treat cancer, the doctor may decide to perform either surgery, radiation therapy, or chemotherapy. These surgeries may also provoke night sweats. Although in this case, the doctor may prescribe some drugs to use to help fight against night sweat.
