On 9 April 2019, at
West Kowloon Court, Chan and eight others were found guilty of
public nuisance and
incitement over their roles in the
2014 Hong Kong protests. Earlier, Chan scheduled a full-body
health check-up to reassure her mother that she was physically ready to endure a jail term if this were to happen. Her physical examination was conducted in a private hospital on 4 April. Chan received the results of her health check on 11 April, followed by a consultation in
Canossa Hospital on 17 April. The test results revealed there was something unclear with her brain. On 18 April, Dr Edmund Woo Kin-wai, a
neurologist, found that Tanya Chan had a
meningioma, a type of brain tumour larger than a ping-pong ball. The tumour was considered dangerous as it pressed on Chan's
brain stem,
nerves, and
blood vessels. On 23 April, medics stated that Chan needed open brain surgery to remove the tumour as soon as possible, followed by
radiotherapy sessions. According to medics, there was no clarity whether the tumour was caused by cancer, and an open
brain surgery would be necessary for additional medical insights. On 24 April, the trial at
West Kowloon Court adjourned her sentencing to 10 June, since Chan required brain surgery within two weeks. The other eight Occupy Central leaders were sentenced to different punishments, ranging from 200 hours
community service to 16 months of
jail time. In the same day, Chan asked Legislative Council president
Andrew Leung for leave from her legislative duties while she sought further treatment. Before speaking about her illness, she also asked
Hongkongers to continue their fight for democracy and to believe in their faith. ==Later career==
