The 15|35 Society
Testicular Cancer Foundation
Testicular cancer strikes men as young as 15 and peaks between 15 and 35. It's survivable — but only when caught early. Members of The 15|35 Society fund the education, awareness, and support that make early detection possible.
Two numbers. One mission.
$15 represents the age when risk begins. Men as young as 15 are diagnosed with testicular cancer every year, yet most have never been told to check, never learned the signs, and never heard that it's survivable when caught early.
$35 represents the age when risk peaks and begins to decline. Advocates who give at the $35 level have passed through the window. They give for the men still inside it.
Most men in the 15–35 window have never performed a self-exam. Early detection changes everything. Monthly giving funds the education that changes that.
Every dollar does real work.
Education & Awareness
Funding self-exam education, school programs, and digital campaigns that reach men in the 15–35 window before a missed diagnosis becomes a crisis.
Patient Support
Resources, navigation support, and community for men and families moving through a testicular cancer diagnosis, from first symptoms through survivorship.
Research & Advocacy
Advancing research into treatment, late effects, and quality of life outcomes, and advocating for young men's health at the national level.
Most men who die from testicular cancer didn't die because it was incurable. They died because no one taught them to look.
