When 28-year old Artyom Sidorkin underwent surgery to remove a suspected cancerous tumor that was causing him extreme chest pain, medical staff in Izhevsk in the Urals, Russia, were startled to see a tiny tree growing inside Sidorkin?s lung. The five-centimeter fir tree branch was discovered when surgeon, Vladimir Kamashev, took part of the man?s lung for a biopsy. Dr. Kamashev recalled: ?I thought I was hallucinating; I asked my assistant to have a look: ?Come and see this ? we?ve got a fir tree here.? He nodded in shock. I blinked three times as I was sure I was seeing things.? Doctors think he might have inhaled a seed, which was deposited into his lung tissue. The seed sprouted there, and grew until it started touching capillaries in the tissue, causing Sidorkin extreme pain. The branch was later removed. ?It was very painful. But to be honest, I did not feel any foreign object inside me,? said Sidorkin of his strange experience. ?I?m so relieved it?s not cancer.?
