Cancer
Various studies have suggested that hives could be associated with particular types of cancer like lung and gastrointestinal cancer, as well as lymphoma. When hives are accompanied by some of the cancer symptoms like abdominal pains, loss of weight, night sweats, jaundice, hemoptysis, lymphadenopathy, or just coughing, then your doctor needs to carry out some tests to find the cause. A combination of some of these symptoms with hives may be a serious call for alarm and should be diagnosed immediately.
