No, it's an excellent example, you're just missing the point. X-rays DO contribute to the chances of getting cancer, it's just that an X-ray by itself cannot to directly linked to it. There are all sorts of toxins and carcinogens in the world. A person can get some X-rays, then a CAT scan, then go on several international flights, have a few drinks, use some equal in you coffee, smoke a few cigars -- all seemingly benign things, and then at 50...sorry, you have cancer. No doctor is going to say, "Yeah, it's because of that X-ray you had 10 years ago! "
The point is, everything has risks -- some more than others. And you have to proceed with caution. Of course, we all take chances to reap the benefits, but when people say that something is absolutley side effect free, they're fooling themselves. When they offer misinformation as "advice" they're being irresponsible.
If someone chooses to use steroids, or peptides, or Sarms or rev-erb agonists or eat donuts and milkshakes, it's all fine. But keep in mind that there's a limit the body can tolerate and remain healthy.
