The occipital lobe of the brain is located at the back of the skull. The occipital lobe connects the parietal and temporal lobes to the cerebellum. It is part of the cerebrum, the upper and largest portion of the human brain.
A brain tumour in the occipital lobe of the brain causes total or partial blindness, misunderstanding of visual information, comprehension problems with written words and seizures.
The World Health Organization (WHO) classifies brain tumours from inactive or benign at Grade I to the most aggressive, or malignant at Grade IV. Each grade helps identify rate of growth and predicted tumour behaviour.
Brain tumours in the occipital lobe are identified first by an MRI or CT scan after symptoms like severe headaches, nausea, vomiting and an intolerance to light present themselves. Even after an MRI or CT scan, the tumour may not show up until it grows considerably larger.
Treatment for an occipital lobe tumour is determined by where it is located. One option is surgery to remove the growth, targeted radiation over several weeks to shrink the tumour, chemotherapy to poison the cells and immunotherapy, which uses biological agents to destroy the tumour cells.
Inoperable vs. Operable
Brain tumours, depending on their location, may be inoperable. If the tumour is growing deep within the brain matter, and the surgeon cannot remove it without causing severe damage to the brain, the tumour is inoperable.
