If you read the article, it has an answer for (b) that so far works in culture and in human tumors inside animal models; Not quite the real thing, but probably the farthest you can get before human trials, and it is quite far.<p>With respect to (a) - yes, there are tens or hundreds of fundamentally different cancers. But there&#x27;s a reason we call them all &quot;cancer&quot; - which is they do have common traits (unchecked growth, glycolisys as the preferred and often singular mode of metabolism - a.k.a the Warburg effect mentioned in the article), so it&#x27;s not unthinkable that a few bullets could work for significant majority of cancers. It appears that the naked mole rat, a cancer-free rodent[1], has multiple mechanisms against cancer, one of of which is an overcrowding control.<p>I&#x27;ve read numerous accounts of the usefulness of fasting in fighting cancer (including complete remissions), but no scholarly articles that go far enough. The ignorance about fasting&#x27;s effects on the human body and how long a relatively person can fast with no irreversible damage (hint: close to 50 days), is quite staggering. The body switches to ketones as an energy source, which the vast majority of cancer cells cannot use. I have found peer reviewed papers showing that fasting makes chemotherapy significantly more effective. It could be your (a) bullet, because it relies on the (b) differentiation.<p>Wikipedia[0] doesn&#x27;t list an exact date, but apparently, the Warburg hypothesis dates to around 1920. The Nobel Prize for this discovery was awarded to him in 1931.<p>I&#x27;ve first read about Warburg and his discovery in 1999, and I asked every MD I met at the time about it - not a single one was aware of it. Somehow, everyone is so specialized today that knowledge that should be common isn&#x27;t. I assume once a successful therapy based on this effect is developed, though, it will become common knowledge.<p>[0] <a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Otto_Heinrich_Warburg" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Otto_Heinrich_Warburg</a><p>[1] <a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Naked_mole-rat#Resistance_to_cancer" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Naked_mole-rat#Resistance_to_c...</a>
