The report, from the McCabe Centre for Law and Cancer and commissioned by Cancer Council Victoria, surveyed more than 200 Victorians affected by cancer, including people with lived experience, carers and the professionals supporting them.
Neroli Padfield was diagnosed with breast cancer in 2024 and underwent surgery, chemotherapy and radiotherapy. Even with private health insurance, she spent about $10,400 on specialist appointments, tests and medications.
"As I was putting it all into a spreadsheet, I thought: 'Wow, this is ridiculous,'" she said. "The costs started even before I was diagnosed."
Ms Padfield, who describes herself as "lucky" to have kept working during treatment with flexible hours, said the financial burden continues long after active treatment ends. "I'm still paying for having had cancer, and I think I will be paying for a number of years."
Hayley Jones, director of the McCabe Centre for Law and Cancer, said many people told researchers they felt "completely blindsided" by out-of-pocket fees as they left specialist appointments, and some said they skipped medications because they could not afford them.
"Some of the people we interviewed had up to $10,000 in expenses in about two years," Ms Jones said. "That ranges from specialist fees to medications, treatment and reconstructive surgery, as well as travel to appointments and accommodation, particularly if people live regionally."
Hospital parking, diagnostics and medication also came with unexpected costs, the report found.
"A cancer diagnosis is life-changing, but unfortunately it also comes with unnecessary legal and financial burdens," Ms Jones said. "These challenges … often arise at times of crisis and are shaped by systems that are complex, fragmented and poorly aligned with the realities of cancer and caring."
The report's key recommendations include strengthening enforceable workplace rights and protections, reforming superannuation, and increasing awareness of the financial impacts of a cancer diagnosis.
