Bad breath



Can bad breath be a symptom of cancer?


Bad breath [halitosis] occurs because of several reasons. For example - mouth diseases, cavities, gum disease, eating certain foods with onion, garlic, spicy ingredients, and tobacco use can cause bad breath. Furthermore, systemic diseases such as respiratory disease, gut disease, liver disease and certain kidney diseases can also contribute to bad breath. Cancer of the mouth can be included under mouth disease.
