What Science Says About... Cancer-Causing Parasites: the Evidence-First Guide to Unexplained

Three parasitic worms are officially recognized as definite causes of human cancer. Only three.Two liver flukes and a blood fluke sit alongside tobacco smoke on the world's shortest list of proven biological carcinogens - the only animals there. Their tumors follow rivers, snails, and local cuisine rather than genetics, which is why bile duct cancer devastates one Thai province and barely registers elsewhere.Yet most infected people never develop cancer. The evidence is stranger still: a Nobel Prize awarded for getting this wrong, a near-identical fluke left unclassified because too few researchers looked, and a real finding inverted online into a dangerous cure myth.Inside, you'll discover: - Why a parasite's chemistry damages DNA decades before any tumor appears - How removing a parasite from a population tests causation itself - Where legitimate scientific disagreement ends and misinformation beginsWhat Science Says About... separates evidence from hype across every subject it examines.Start reading, and follow the evidence.
