I personally would not be surprised if cancer is a virus. Mutated cells are linked to cancer, and tumors are parasitic, like viruses. The government actually tells us that cancer can be caused by viruses. For instance, cancer.gov lists several types of cancer caused by HPV’s (human papillomaviruses) on their website https://www.cancer.gov/about-cancer/causes-prevention/risk/infectious-agents/hpv-vaccine-fact-sheet)
And it is also very interesting how the cancer numbers have increased along with the increase in vaccinations, which are known to be contaminated with different viruses from different animal species.
