About BTSS

“We come together from all walks of life, from many different circumstances. We need not walk alone.”

Who are we?

We are a community of brain tumour patients, caregivers and friends who come together from all walks of life and many different circumstances to support and help each other in our journeys so that no one with a brain tumour would walk alone.

Established in March 2014, BTSS was accorded Institution of Public Character(IPC) status by the Ministry of Health on 8 June 2022.


The diagnosis of a brain tumour can be devastating. BTSS patients and caregivers understand this first-hand. We want to share our experience and knowledge to help patients and families at every stage – from the diagnosis to the treatment, rehabilitation and assimilation back to society.

Supporters celebrate the establishment of Brain Tumour Society (Singapore).
