Smokler revealed in 2024 that she had been diagnosed with glioblastoma, an aggressive and fast-growing form of brain cancer that is considered one of the most difficult cancers to treat.

A mother of three, Smokler was candid about her diagnosis from the very beginning, documenting her journey through treatment and sharing the realities of living with cancer with the same honesty that made her famous.

She openly discussed everything from radiation treatments to hair loss, helping countless others facing similar challenges feel less alone.

In one memorable description, Smokler compared the disease to "an octopus with tentacles," a powerful image that captured how glioblastoma spreads into healthy brain tissue, making it nearly impossible to completely remove through surgery.

Just weeks after her diagnosis, Smokler learned the cancer had advanced to Stage 4.

Despite the devastating prognosis, she continued to share her experience with courage, humour and remarkable transparency.

Smokler launched Scary Mommy in 2008 while she was a stay-at-home mom looking for an honest outlet about the realities of parenting.

At a time when many parenting websites focused on perfection, Smokler built a community around the messy, exhausting, hilarious and sometimes overwhelming truth of raising kids.

Her humour, self-deprecating style and willingness to say what many parents were thinking helped turn Scary Mommyinto one of the internet's most successful parenting brands.

For countless moms and dads, she was one of the first voices to say that parenting didn't have to be perfect to be meaningful.

Her legacy lives on in the community she created and in the millions of parents who felt seen because she was willing to tell the truth.
