Myanmar's front-line medical workers are finding themselves in a precarious position, torn between their patients and working for a military government enforcing a brutal crackdown on the country. Moe is 53 years old and has stage three breast cancer. She used to go for radiotherapy treatment every three weeks at the state-run Mandalay General Hospital in northern Myanmar. But the day after the military deposed Myanmar's elected government in a coup on 1 February, the hospital closed its doors. Doctors, nurses and other medical workers all walked out in protest and have not returned.
