Not conclusively. Some studies find that glyphosate causes increased incidence of non-Hodgkin lymphoma [0], although most environment regulators have minimized these results. Anecdotally, in my hometown, of the two men who over the last several decades personally have applied the most glyphosate (although, to be fair, most other herbicides as well), one is already dead before his time from cancer and the other's health is failing. Humans shouldn't die painfully in their 50s.
It's worth noting that the chemical companies have long histories of inventing a new kind of poison and then covering up what it does to humans so that it takes decades to figure it out. Such was the case with DDT.
Has this been determined?
