The five-year survival rate for men with prostate cancer and a Gleason score of 7 is 98 percent, according to Cancer Research UK. A Gleason score of 7 indicates an intermediate level of cancer.
The Gleason scale rates cases of prostate cancer on a scale of 2 to 10, with higher scores assigned to cancers that are growing more quickly. A Gleason score of 7 indicates a moderate growth rate. While doctors are likely to watch and wait when a cancer has a low score of 2 to 6, with an intermediate score of 7, they are more likely to suggest surgery or radiation treatments, as Cancer Research UK explains.
