He initially responded well to several rounds of antibody-drug conjugates (ADC), a treatment that uses an antibody to deliver a potent drug directly to cancer cells.
Eager to regain his active lifestyle, he returned to marathon training. However, his doctor later discovered the cancer had adapted, and the treatment was no longer effective.
Even after switching to traditional chemotherapy – notorious for its severe side effects – Mr Lim continued training, running four times a week.
When he was diagnosed, he named his tumour Caleb and saw it as something he would have to live with rather than get rid of.
While Mr Lim was determined that his cancer would not define him, he was also upfront about the ways it affected his life.
“Whether in our first year, into our fifth year, or in remission, I now think that perhaps once you have cancer, you never ever truly live a life completely away from it and learning how to live with it is one of the hardest learning curves we’ve had to face,” he wrote on Instagram.
