Woman I knew had a spot on her lungs during a checkup, went in for a biopsy. Doctor that did the biopsy fucked up and hit an artery filling her lungs with blood. Barely pulled through, but then died a couple of weeks later from a blood clot caused by the mess.

If it's one thing I've learned, it's that the more you are able to avoid hospitals, the healthier you are likely to become.
