Understanding
Lung Cancer -- An Overview
Types
of Lung Cancer
Cancers
that begin in the lungs are divided into two major types, nonsmall
cell lung cancer and small
cell lung cancer, depending on how the cells look under a
microscope. Each type of lung cancer grows and spreads in
different ways and is treated differently.
Non-small
cell lung cancer is more common than small cell lung
cancer, and it generally grows and spreads more slowly. There
are three main types of nonsmall cell lung cancer. They are
named for the type of cells in which the cancer develops: squamous
cell carcinoma (also called epidermoid
carcinoma), adenocarcinoma,
and large cell carcinoma.
Small
cell lung cancer, sometimes called oat
cell cancer, is less common than nonsmall cell lung
cancer. This type of lung cancer grows more quickly and is
more likely to spread to other organs in the body.

The features of their growth and spread are very
different, so is their treatment.
