Hi, I cannot get a straight answer from anybody regarding this issue, so have come here. I have been an occasional user of Roundup Weedkiller for the past ten years. I have CLL/MCL. I read yesterday that it was declared a "probable" carcinogen, causing B Cell Non-Hodgkin's malignancies. It has no warnings on the packaging. Some research suggests that you need a large exposure; another that not much could do harm. Does anyone have a handle on this?
