When searching for cancer fighting natural compounds the most interesting are those that cause apoptosis (natural cancer cell death without damaging healthy cells)
Most promising are certain polyphenols like resveratrol, curcumin. lycopene, egcg, and lupeol
The real magic is in the synergetic effect of combining.
Some combinations improve the uptake like curcumin and piperin from black pepper, or adding olive oil to tomato sauce or soup to improve the uptake of both lycopene and lupeol, or resveratrol found in wine grapes with egcg found in green tea
And some combinations combine to target the different pathways to cause the wanted apoptosis (cancer cell death). See illustrative image

Interesting to note is that all mentioned polyphenols are hydrogen oxides. A simpleton would say it is like water (h2o) but it is not. Even tho water is an hydrogen oxide, these molecules are far more complex and give several food the dark, red, blue, purple, or green color

Besides polyphenols look at the minerals selenium and zinc where zinc needs a zinc ionophore like green tea egcg or quercetin to improve intake. And look for the vitamins, c, d, e, and b2 in relation to anti cancer
