German doctors remove 40-pound tumor from woman

This is not yet the world's biggest tumor, but it is still unbelievable. German doctors successfully removed a 40-pound (18kg) malignant bone tumor from a Saudi Arabian woman. The tumor was growing in her pelvis and represented 1/3 of her body weight.
It was previously thought the woman would only live for a few more weeks when she arrived in the hospital in September, but after five operations, the patient is well enough to go home now.

The biggest tumor ever removed is a 45kg tumour which is 4 feet 5 inches in dimension. The tumor has been growing in the patient's buttocks since the age of 12 and after 24 years, doctors in the province of Guangdong removed it in a operation that took more than eight hours.
