I’m at the airport smiling as I go through check in. My emotions are tightly packed into my 7kg carry on baggage. False bravado. I’m not leaving on holidays, but everyone is telling me to enjoy my trip. The truth is I’m leaving Yangon to go to hospital in Bangkok. A suspicious looking mole on my arm has changed appearance in recent weeks and the Yangon doctor fears it might be skin cancer. Living in Myanmar, I’ve been wary of illnesses like dengue, malaria and hepatitis.
