A five-centimeter fir tree has been found in the lung of a man who complained he had a strong pain in his chest and was coughing blood.

The 28-year-old patient, Artyom Sidorkin, came to a hospital in the city of Izhevsk in Central Russia last week, Komsomolskaya Pravda daily reports.

Doctors x-rayed his chest and found a tumor in one of the lungs. Suspecting cancer, they made a decision to perform biopsy, but when they cut the tissue, they were amazed to see green needles in the cut.

So the best guess is that this dude "inhaled a small bud, which then started to grow inside his body." Which is just fucking great. As if I needed any-fucking-thing else to worry about.

And yes, this SCIENCE FACT gives horrifying, IRREFUTABLE credence to this beloved children's tale, which totally happened to my friend Alex's cousin's babysitter's grandma, and which gave me no shortage of cold-sweat nightmares as a child.
