D37: Neoplasm of uncertain or unknown behaviour of oral cavity and digestive organs

The group of conditions categorized as "Neoplasm of uncertain or unknown behaviour of oral cavity and digestive organs" refers to abnormal growths that may be found in the oral cavity (mouth area) or parts of the digestive system, such as the stomach, liver, and intestines. These growths can be benign (non-cancerous), precancerous, or even cancerous, but tests have not yet been able to definitively determine their nature. Affected individuals may experience a range of symptoms depending on the location and size of the neoplasm. These can include difficulty swallowing or feeling a lump in the throat for oral neoplasms, or nausea, abdominal discomfort, changes in bowel habits or unexplained weight loss in case of digestive organ neoplasms. These conditions can develop due to a range of causes such as genetic factors, infection, or exposure to certain chemicals or substances. Essentially, these are conditions of abnormal cell growth where the potential level of harm to the individual is not yet entirely understood.
