M = Metastasis
The M category tells you if there are metastases to
distant sites. Lung cancer tends to spread to the brain,
adrenal gland, and to the lung without the primary tumor.
M scores for lung cancer include:
M0
means the cancer hasn’t spread to distant sites.
M1
means the cancer has spread to distant sites.
M1a
means the cancer has spread: a) from one
lung into the other lung; b) into the lung’s lining
(pleura) and has formed secondary tumors; or c)
into the fluid within the tissue lining around the
lungs or the heart.
M1b
means the cancer has spread to areas
outside the chest area.
4.3 Stages of lung cancer
Table 1 shows the staging groups labeled by Roman
numerals 0–IV. Occult carcinoma is also included. In
general, earlier cancer stages have better outcomes.
However, doctors define cancer stages with information
from thousands of patients, so a cancer stage gives an
average outcome. It may not tell the outcome for one
person. Some people will do better than expected. Others
will do worse. Other factors not used for staging cancer
are also very important. Some of these factors include
your general health, type of lung cancer, and molecular
test results.
