I have a question, if we start growing tank meat, cells that have cancer like qualities might be very successful in a tank. Cells with no density or attachment growth inhibition will kill the host. (or at least create an ugly tumor in the carcass) Removing the animal removes this filter. How dangerous is to eat cooked cancerous cells? How much more dangerous would this be if they were human, or even my cells? I wouldn't want to end up looking like this: https://en.wikipedia.org/wiki/Devil_facial_tumour_disease https://en.wikipedia.org/wiki/Devil_facial_tumour_disease could we solve this by growing complex tissues, rather than a loose cell soup?
