For the past several years a 31-year-old man from India had been watching the tumor emerge from the back of his skull.

Following treatment, including chemotherapy, the mass continued to grow. He was feeling a heaviness in his head, which ached constantly, and his vision was blurred. Doctors in India say his brain tumour grew so big that it weighed nearly four pounds and measured nearly 20cm by 30cm by 30cm.
Doctors successfully removed the mass during an intensive, six-hour operation and explained that about 10 percent of the tumor was growing within the patients skull, putting pressure on his brain and causing him to lose his eyesight; if not treated successfully, it could have caused neurological damage or paralysis.
He is now recovering well and is expected to regain full eyesight.
