 So by the mid-2000s, a new idea is and was being born around cancer. Let's not attack just the cancer cell. Let's attack these homes, these nutrients, these metabolic pathways that cancers build around themselves. And that's where I come in. That's where I grew up. Because I, like many other people, was disappointed but also excited about the idea that maybe the problem is not just the cancer cell, but this home, this environment, micro environment, nutrient environment, metabolic environment, immune environment, vascular blood vessel environment that the cancer builds around itself. The advantage of these environments is that unlike the cancer, they don't mutate. They aren't billions of them. They are relatively static.
