Illness Hallenga was diagnosed with breast cancer in 2009, at the age of 23. Her doctor originally dismissed a tumour on Hallenga's breast, leading to a late diagnosis. As a result, she lived with stage four breast cancer. Despite Hallenga's cancer having spread to her liver and her bones, and having had a lesion on her brain, she survived her original prognosis by having terminal cancer for over five years. In 2021, Hallenga's condition was stable and her cancer had not been progressing for three years.

CoppaFeel! Hallenga and her twin sister Maren decided to devote themselves to educating young people about breast cancer. The charity received frequent media coverage. In January 2017, Hallenga stepped down as the CEO of CoppaFeel! to move to Cornwall and write a memoir; Natalie Haskell succeeded her as CEO.
