11 Critical Mouth Cancer Symptoms to Recognize Early

7. Bad Breath

Obviously bad breath alone does not indicate mouth cancer, however, persistent bad breath may indicate an early warning sign of cancerous cells. Bad breath may be a sign of oral, stomach, esophageal, pulmonary, or pharyngeal cancer. In many cases, this is due to decay. Of course, individuals may find smoking can also contribute to bad breath through a combination of dry mouth, bacteria, and the tobacco itself. Thus, it is important for individuals to consider other potential causes behind their bad breath and, if needed, bring this information to a dentist or doctor who can further help them narrow the causes.
