Popular mommy blogger dies at 48 two years after devastating cancer diagnosis

As Scary Mommy expanded from a personal blog into a major parenting brand, Smokler built a following with her honest, often self-deprecating take on motherhood. She went on to speak at blogging conferences, author bestselling books, appear on national television programs and earn three Webby Awards, her biography states.

"Jill spent her life telling the truth about motherhood - that it could be wonderful and impossible in the very same breath - and in doing so, she gave millions of women permission to stop pretending and feel a little less alone," her family shared in a statement following her passing.

"She was funny, fearless, generous and entirely herself. More than anything she built, Jill was proudest of her three children, Lily, Ben and Evan. We are heartbroken to lose her, and endlessly proud of the mark she left on the world."

"I am definitely grateful that I don't remember the looks on their faces when I didn't recognize them," she said. "That must have been gutting."

"Thank you, Jill, for everything. May you rest in peace," the Scary Mommy post concluded.

About 13.9% of all brain tumors are glioblastomas, according to the American Brain Tumor Association. More than 12,000 new cases are diagnosed in the U.S. each year.

Median survival is approximately 12 to 18 months after diagnosis, even with treatment. Only about 5% to 7% of patients survive five years after diagnosis, data shows.
