The Life Expectancy Discrepancy
Canadian Men are: 79% more likely to die from heart disease, 57% more likely to die from type 2 diabetes 40% more likely to die from cancer 4 times more likely to commit suicide.

Grade Description . Grade 1 Small, uniform glands with minimal
nuclear changes
Grade 2 Medium-sized acini, still separated by stroma but more closely arranged.
Grade 3 The most common finding in prostate cancer biopsies. Marked variation in glandular size and organization, infiltration of stromal and neighboring tissues.
Grade 4 Markedly atypical cells with extensive infiltration into surrounding tissues.
Grade 5 Sheets of undifferentiated cancer cells.
Gleason Grading
Donald F. Gleason
Gleason, Cancer Chemother. Rep. 1966.
Gleason Score = most frequent grade + 2nd most frequent grade
