M = Metastasis
The M category tells you if the cancer has spread to distant sites. Para-aortic,
common iliac, inguinal, supraclavicular, scalene, and cervical lymph nodes are distant
from the prostate. These nodes are shown in Figure 5. Prostate cancer tends to
metastasize to bone then the lungs and liver. M scores for prostate cancer include:
means it is unknown if cancer has spread to distant sites.
means that there is no growth to distant sites.
means that the cancer has spread to distant sites.
is cancer that has spread to distant lymph nodes.
