A fir tree was found in a man's lungs suspected of having cancer!

In 2009, Russian doctors operated
on Artyom Sidorkin to remove what they
thought was a tumor in his lung. When
they opened him up, they were surprised to
find a fir tree growing instead! Doctors
speculate that the man must have inhaled
a seed that eventually sprouted and grew
inside him. The growing branches were
even started to cause him to cough up
blood because they were puncturing his
lungs!
