Umhlaza wemiphunga
Inkcazo emfutshane:
Umhlaza wemiphunga (okwaziwa ngokuba ngumhlaza we-bronchial) ngumhlaza wemiphunga onobungozi obangelwa zizicubu ze-epithelial ze-bronchial ezine-caliber eyahlukileyo. Ngokwembonakalo, wahlulwe waba yi-central, peripheral kunye ne-large (mixed).
I-Epidemiology
Umhlaza wemiphunga yeyona thumba ixhaphakileyo kwaye yeyona nto ibangela ukufa kwabantu abanesifo somhlaza kumazwe aphuhlileyo. Ngokwedatha ye-International Cancer Research Institute, kukho malunga nesigidi esinye seziganeko ezintsha zomhlaza wemiphunga kwihlabathi liphela minyaka le, kwaye ama-60% ezigulana ezinomhlaza ziyafa ngenxa yomhlaza wemiphunga.
ERashiya, umhlaza wemiphunga uphakathi kwezifo zethumba, ubanga i-12% yale ngxaki, kwaye ufunyaniswa njengomhlaza wemiphunga kwi-15% yezigulana zethumba ezifileyo. Amadoda anenani eliphezulu lomhlaza wemiphunga. Ithumba elinye kuzo zonke ezine ezinobungozi emadodeni ngumhlaza wemiphunga, kwaye elinye kwishumi elinesibini lezigulana emadodeni ngumhlaza wemiphunga. Ngowama-2000, umhlaza wemiphunga wabulala amadoda angama-32% kwaye i-7.2% yabasetyhini bafunyaniswa benezigulana ezinobungozi.
