Hanoi - Vietnam : The largest tumor ever diagnostziert in the country, away from the leg of a young patient. Last month, the tumor, which now weighs 80-90 pounds, grown three inches in diameter and grow. The 31-year-old Duy Hai have been damage to hip and spine and was suffering from respiratory distress, said the director of the Cancer Hospital in Ho Chi Minh City, Le Minh Hoang. Hai lives under constant severe pain and can move in four years hardly. In November, a group of American doctors help in the operation. "It's a long waiting time for surgery," said Shark. "I wish that the foreign doctors could come earlier to help me." The American doctors had been asked for help after experts found in Vietnam last month, no way to remove the overgrowth. The operation should take, according to Minh between eight and 14 hours. Danger exists because the tumor would be fed by major blood vessels. The tumor has been growing for 30 years in the right leg of the Vietnamese - in spite of an attempt 14 years ago, to stop the growth with the aid of a amputated at the knee. Shark family is too poor to afford another surgery may therefore want to take over the hospital in Ho Chi Minh City .
