A woman who had one of her legs amputated to keep her alive has discovered it is growing back an alarming rate.
Mandy Sellars, 36, suffers from a rare form of Proteus Syndrome which has left with a normal size upper body but giant legs and feet.
The condition is thought to have affected Elephant Man Joseph Merrick in the 19th century.
In January 2010, Mandy, of Bolton Avenue, Huncoat, had her left leg amputated after coming down with a string of infections.
But since then the leg has grown back and now has a circumference of one metre and weighs more than three stones.
Bacup-born Mandy said: "At the time of the operation, a part of me hoped it would stop growing but I think deep down I knew it wouldn’t stop.
"The doctors don’t really know what’s going on.
"My leg seems to have a mind of its own and keeps growing."
Mandy may be the only person in the world with this particular form of Proteus Syndrome which is why doctors are struggling to find answers as to why the leg keeps growing.
Following the amputation Mandy began learning to walk with a prosthetic leg and has undergone days of intensive physiotherapy in Preston.
But the weight of her leg caused the prosthetic one to break.
A new one has been made and Mandy is continuing to learn how walk with it.
Due to her mobility problems she has had to put her volunteer work at the RSPCA centre in Altham on hold for awhile.
Nevertheless Mandy remains incredibly upbeat and positive.
She said: "I have cut down on processed food and I have started to eat more healthily to see if that makes a difference.
"Hopefully I will be walking on my own soon and will have more freedom. I am determined to be as independent possible."
