If it comes to cancer cure there are so many interesting rabbit holes out there:

* Oxygen therapy by Otto Warburg (Nobel laureate)

* Diet by Galina Shatalova (neurosurgeon)

* 5 biological natural laws by Ryke Geerd Hamer (physician)

* Oil-Protein Diet by Dr. Johanna Budwig (pharmacist)

* Cannabis Oil by Rick Simpson

But everything that heals and doesn't bring money to the pharma mafia is pseudoscience.
