Vietnamese man has 90kg tumour

Nguyen Dua Hai from Vietnam has a tumour that measures 1.2 meters in diameter and weighs up 90kg.
The 31-year-old from the town of Da Lat is unable to move and can only sleep sitting up.
His mother, 61, has reportedly taken care of all of her son's basic needs. She told Tuoitrenews that she worries her declining health won't let her do that anymore.

Hai was born a normal child but developed the tumour soon after.
When he was four years old, his right leg showed abnormal signs of growing much faster than the left.
At 17, the tumour weighed about 25kg.  He then had an amputation at the knee at Lam Dong General Hospital.

Doctors at the hospital could not diagnose the cancer.
