Lung cancer can be classified as --
--- bronchoalveolar- alveolar
--- large cell carcinomas
There is approximately 75- 85% of non-small cell lung cancer and 15- 25% of small cell cancers of the lung.
Non-small cell cancer of the lung.
develop in the outer portion of the lung.
does not have any symptoms found on a chest x-ray.
it may spread to other parts of body. Such as, the central nervous system, the adrenal gland and the other half of the lung.
b) Bronchoalveolar Carcinoma
Can be found throughout the respiratory trait.
Seen as a mass on a chest x-ray.
About 75- 90% survival for 5 years after the surgery.
c) Squamous cell carcinomas.
Can be found in the more central portion of the lung.
Cause symptoms in early stage. The common symptoms are coughing, stortness of breath or pneumonia.
d) Large Cell Carcinomias
No significant structural characteristics when viewed under a microscope.
Small Cell Cancer of the lung.
Grow rapidly and metastasize to other parts of the body at early stage.
Can be found as a mass in the central portion of the chest on chest x-ray.

(2) ---> blood stream ---> bone
( ---> spread )
