Not a problem, I also have a colleague at work with the same, they also "think" its caused by roundup. Everything causes cancer and bad health, so I don't pay much mind. I def have empathy to anyone suffering for any reason, don't get me wrong.
As far as your gravel, we use "bareground" herbicide. Its a soil applied blanket treatment. You spray every sq ft of your gravel with a particular chemistry, and it prevents anything from growing. Imazapyr, Ecomazapyr are two good ones. They sterilize everything. The timing is also important. Seasonal moisture will help drive the product down to perennial roots. Sometimes pre emergent products alone will not work, because they are mostly targeting annual weeds and not perennial. I sometimes mix the two classes to really get a true bareground with little to no "escapes." Just read label for rates and uses and precautions
