A 40-year-old with a severe form of cancer such as lung or brain cancer could be liable for a $71,880 (£56,000) surcharge, while those with metastatic cancer could see a rise of $140,510, according to calculations by liberal think tank Center for American Progress.
People with colorectal, kidney and other cancers, and those with breast cancer under 50, may have to pay a surcharge of $28,230 (£22,000), and a middle-aged person with autism could have to pay $5,420 (£4,200) for coverage.
And a completed pregnancy, with no or minor complications, would result in a premium hike of $17,060 (£13,200) – a 425% increase.
