Zoleka was first diagnosed with breast cancer at 32 and was in remission when the cancer resurged last year. She had been receiving treatment for metastatic cancer in her spinal cord, liver, hip, lung and ribs, according to her Instagram, where she documented her treatment journey.

She developed the hashtag #TerminallyFree and started a series where she aimed to remind followers “that within us all lies a power to fight for continuance, albeit terminal cancer.” She launched a YouTube series under the same name.
