Cancer Caused by Parasites? Known Since the 1990's

I saw this on a site called Hat's on Telegram's platform. It was uploaded January 18, 2024.
Dr Lee Merritt : “Doctors around the world are showing that cancer is intracellular parasites”😳
“If you look at cancer under a light microscope, its essentially indistinguishable from parasite egg sacs”
Is that why they tried so hard to shut down Ivermectin and other anti-parasitics during Covid?
