Alveolar cell carcinoma


Recommended Posts

hi, i tried to do a search, but i couldn't find much info. here's what i found...hope that it helps (you might want to check the websites and do a more thorough search though).


Bronchoalveolar carcinoma or alveolar cell carcinoma is a non-small cell carcinoma that can be found throughout the respiratory tract. When it is discovered as a single mass on a patient's x-ray, this type of lung cancer has an excellent prognosis. Five year survival after surgery is in the 75-90 percent range. If, however, it is found in its diffuse form (meaning it has spread beyond a single mass), the prognosis is quite poor.
