3. Cancer
If you start sweating more, especially at night it can be a cause for alarm. However, just because you are sweating more does not necessarily mean that you have cancer. It is important to know that there are some types of cancer that can cause night sweating as a symptom.
Some types of cancer that may cause night sweating include leukemia, lymphoma, carcinoid tumors, liver cancer, bone cancer, and mesothelioma. Night sweating is not the only symptom that a person suffering from these cancers will experience.
Typically, a person with one of these types of cancer will also have some other symptoms such as a rapid weight loss. They may also experience fevers for no reason. Once again, the best thing to do if you start experiencing excessive sweating is to make sure that you let your doctor know so that the underlying cause can be determined.
