Is this fir real?

Surgeons operating on a man for lung cancer found a FIR TREE growing inside him, according to today's British Daily Mail.

Russian doctors discovered the 5cm tree when they opened up 28 year old Artyom Sidorkin to remove what they thought was a tumour.

Medical staff believe that Sidorkin inhaled a seed, which later sprouted into a small fir tree inside his lung.

Doctors say Sidorkin's coughed of blood which was caused by the tiny pine needles piercing blood capillaries.

"It was very painful. But to be honest I did not feel any foreign object inside me," said Sidorkin. "I'm so relieved it's not cancer."
