A 13-member medical board that held a meeting around 11:00am today to decide the course of Muktamoni's treatment came up with the decision after receiving her biopsy report last evening.

"Her situation is critical and we will primarily focus not to amputate her affected hand," said Dr Samanta Lal Sen, national coordinator at National Institute of Burn and Plastic Surgery of the DMCH told The Daily Star.

The medical board members will be present during the surgery.

On Saturday, DMCH doctors conducted the biopsy on Muktamoni, who has been afflicted by the disease mainly in her right hand, the condition leading to her hand swelling up like a bee hive. But it all started a long time back.

When Muktamoni was three years old, her parents observed a small swelling in her chest. After a few days, the marble-like protrusions appeared underneath her left armpit. Thus began a round of treatment that has continued till this very day.

First, Ibrahim took his daughter to local doctors but no improvement was seen.

He said she always feels unbearable pain in the affected hand which is infested with parasitic worms.

"We gave her homeopathy treatment too, for nearly one and a half years, but it did not work," he said
