Eat above to starve cancer.
In autopsies of people who died in car accidents, doctors have found microscopic cancers in 40% of woman (breast) and 40% of men (prostate). Something like 70% of older people have microcancers in their thyroid. But the cancer is harmless -- "cancer without disease." If you block angiogenesis the cancer can't grow. "It's a tipping point between harmless cancer and deadly one."
Li showed a photo of a poor dog with gnarly tumor hanging off its side. The vet gave the dog three months to live. They started antiangiogenesis drugs. In a few weeks, the tumor shrank away completely. They also cured a dolphin of mouth cancer and saw a complete remission of a deadly lip cancer on a horse.
Today there 12 different antiangiogenesis drugs available for people and dogs. They are quite effective for many cancers, but not much for liver, lung, and breast cancers. The problem with these cancers is that by the time they are detected they have progressed too far for antiangiogenesis drugs to do their work.
The good news, Li says, is that "we eat to starve cancer." Lots of foods contain naturally occuring inhibitors of angiogenesis, and many are even better than drugs for blocking angiogenesis (see image above).
