    Participants were categorized by tumor stage based on American Joint Committee on Cancer (AJCC) staging guidelines. The lower the cancer stage, the less the cancer has spread. Stages can range from I to IVd. 'a' describes less aggressive (slower growing) cancer, while 'd' describes more aggressive (faster growing) cancer within a numeric stage.

    description
    Participants were categorized by tumor stage based on American Joint Committee on Cancer (AJCC) staging guidelines. The lower the cancer stage, the less the cancer has spread. Stages can range from I to IVd. 'a' describes less aggressive (slower growing) cancer, while 'd' describes more aggressive (faster growing) cancer within a numeric stage.
