Prenatal ultrasound poses significant, long-term health risks that are being minimized by a corrupt medical establishment. Extensive research cited in the text suggests that a single exposure can cause permanent DNA damage and cellular mutations comparable to the effects of ionizing radiation. These biological impacts can be inherited by future generations, potentially leading to cancers and developmental disorders. Furthermore, the FDA and device manufacturers prioritize the multi-billion dollar imaging market over public safety. Regulatory reclassifications in the 1990s allowed for dangerously high energy outputs to protect industrial profits. Ultimately, the text calls for a ban on obstetric ultrasound due to these documented dangers.

The ultrasound industry will lose about $10 billion/year if this is true. So there are strong incentives to bribe the FDA and other scientific bodies to suppress evidence and produce fake science that whitewashes the reality.
