A man who has brain cancer said that an appointment with an optician saved his life.

The optician referred Voice to an eye clinic at a local hospital, and in May 2020 doctors diagnosed him with a brain cancer, called an astrocytoma, which arises from the cells that surround the nerve cells in the brain.

"I was told it was on the left and right side of my brain and that it would become aggressive," Voice said.

Brain cancers are rare, and the chance that a person in the US will develop a malignant tumor of the brain or spinal cord in their lifetime is less than 1%, according to the American Cancer Society.

In July 2020, Voice underwent surgery to remove 70% of the tumor on the right side.
