Tree Growing in mans Lung? How is this possible~,,

"Russian media has reported that a man who complained to doctors of severe chest pains was told he had a fir tree growing inside his lung.Reports say Artyom Sidorkin, 28, from the Urals region of Russia, is believed to have inhaled a seed which then sprouted inside him.
Doctors were convinced he had cancer after he came to them complaining of agonising chest pains and coughing up blood.
An X-ray showed what was believed to be a tumour, and he was rushed to the operating theatre.
Surgeon Vladimir Kamashev from Izhevsk in the Urals was quoted as saying "We were 100% sure."
"We did X-rays and found what looked exactly like a tumour. I had seen hundreds before, so we decided on surgery."
Before removing the major part of the man's lung, the surgeon investigated the tissue taken in a biopsy.
"I thought I was hallucinating," said Dr Kamashev.
"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."
The 2in (5cm) spruce, which was said to be touching the man's capillaries and causing severe pain, was removed.
Mr Sidorkin, now recovering after the op, said in reports: "To be honest I did not feel any foreign object inside me. But I'm just so relieved it's not cancer."
Biologists are sceptical about a plant growing inside human body.
"It is absolutely impossible for a green plant to grow from this small seed inside a man's body. In order for a plant to start growing from the seed, it needs a lot of conditions - light, then water and certain temperature," said Olga Baranova, a university professor."
