Diagram showing cancer metastasis: At the tumor site, cells invade tissue, then enter blood vessels (intravasation). They travel in the bloodstream (circulation) and exit vessels to form new tumors in tissues (extravasation).

Eminent oncologist and cancer researcher Dr. Wafik El-Deiry is back and doubling down on the unproven claim that COVID vaccines cause "turbo cancers," this time with an added dash of conspiracy theory.
