> Maybe, or maybe we'll discover in 10 years that eating lab grown meat gives you some form of cancer. Until it is used on a large scale for a number of years (as in decades) we have no idea what the effect of consuming lab grown meat has on ones health.

We can know it's safe without a long track record of use because of biology, chemistry, and physics. Cultured meat is the same muscle cells with the same DNA. If it caused cancer but animal meat didn't, that would tell us something new about biology, chemistry, and/or physics.

Your fear-mongering postulates unknown mechanisms of action that science would almost certainly have discovered by now. That's not just unscientific, it's anti-scientific. It's on the same level as, "What if cell phones cause cancer?" or "What if vaping is worse than smoking?"
