Persistent bad breath: when it can be a warning sign according to oncology specialists

Bad  breath , known medically as  halitosis , is a common condition often associated with everyday problems such as poor oral hygiene or the consumption of certain foods. However, when this symptom becomes  persistent  and does not improve despite proper care, some specialists warn that it could be linked to more complex conditions, even certain serious illnesses. Among these, certain types of  cancer  have been studied for their possible relationship with changes in breath odor.
