A change in body odor does not usually mean that a person has a serious illness. It can be associated with diet, sweating, personal hygiene, microorganisms living on the skin, or a variety of health-related factors.
However, certain medical conditions can sometimes affect the smell of the body or breath. In some types of cancer, metabolic changes in the body may produce particular chemical compounds that can potentially be detected in breath or bodily secretions. Scientists have conducted research into whether such chemical patterns could eventually assist with disease detection.
It is important to emphasize, however, that cancer cannot be diagnosed based on a change in smell alone. The same or similar changes can have many other causes, most of which are considerably more common and are not necessarily related to cancer.
For example, persistent bad breath may be associated with dental or gum problems, dry mouth, certain foods and other relatively common conditions. Changes in the smell of sweat can also be influenced by diet, hormonal changes, physical activity, hygiene and numerous other factors.
For this reason, noticing an unusual body or breath odor should not automatically be interpreted as evidence of cancer or another serious disease.
If an unusual change persists for a prolonged period, becomes more noticeable, or occurs together with other concerning symptoms, consulting a healthcare professional is an appropriate next step. A doctor can evaluate the symptoms and determine whether any examinations or tests are necessary.
Past.am reminds readers that a medical diagnosis cannot be made on the basis of a single symptom. In particular, diagnosing cancer requires an appropriate medical assessment and, when indicated, specific diagnostic tests.
