The world's largest brain tumor, weighing a staggering 4.12 pounds, has been successfully removed by a team of surgeons in India.
But in a seven-hour operation, surgeons successfully removed the massive tumour along with skull bone which had invaded into the brain.
Pal had apparently complained of progressive swelling on his scalp, along with headaches and a loss of vision in both of his eyes - all of which are indicators of a brain tumour.
It appeared as if there are two heads mounted on top of each other.
"We have checked all the available medical texts", Nadkarni said. Doctors expect Pal's vision to improve.
Dr Nadkarni added: "Such large tumours are rare and are a surgical challenge".More news: Kamal to start his political journey today

He was then investigated with CT and MRI scans of the brain where specialised CT angiography was performed to study blood supply in the tumor.
The doctors said that the pressure on the brain led to the patient losing his eyesight. Only about 10 percent of the tumor developed inside the skull.
Pal needed 11 units of blood during the entire procedure, and had to be placed on a ventilator right after.
But his wife, Manju, told newspaper The Hindu that they had been told by doctors at three different hospitals in Uttar Pradesh that his large tumour was inoperable.
Pal and his relatives were informed about the high risk of surgery who prepared themselves for seven-hour long surgery which was successful.
The tumor has been sent for tests to detect malignancy (a term used for diseases in which abnormal cells divide without any control and can occupy tissues that are near them), The Hindu reported.
Pal is now recovering in the intensive care unit and is in stable condition, according to The Hindu. He is hopeful that he will eventually regain his sight.
