Mom Diagnosed at 36 Now Helps Thousands Fight Cancer

When doctors kept telling Marielle McLeod her symptoms were just stress, she knew something wasn't right. The South Carolina mother of four pushed for a colonoscopy that revealed a shocking discovery: colorectal cancer at just 36 years old.

"It was not where I expected to be at 36 years old," McLeod told Good Morning Charleston. "Being blindsided by a late-stage cancer diagnosis completely threw me for a loop."

The diagnosis came by accident after McLeod advocated for herself when symptoms grew worse. A series of surgeries and treatments followed, turning her career goals and family life upside down during what should have been the prime years of her life.

But McLeod couldn't shake the feeling that her struggle had a bigger purpose. As soon as she finished treatment, she stepped into advocacy work, determined to help others navigate the same frightening journey.

This June marks nine years cancer-free for McLeod. She now serves as director of a national cancer nonprofit, focusing particularly on the Latino community where colorectal cancer screening rates remain lower than other groups.

Why This Inspires

McLeod transformed her darkest moment into a career helping thousands of patients and families. She works daily to ensure others don't feel alone during their cancer journey, turning her pain into purpose and her fear into fuel for change.

Her advocacy has reached a national stage. This month, during colorectal cancer awareness month, McLeod will be honored at the 2026 Cologuard Classic in Tucson, Arizona, where over 400 patients, survivors and advocates will be celebrated at the PGA Tour Champions event.

Her message to anyone worried about their health is simple and direct: "Screening saves lives. We know our bodies better than anyone else. Don't let anyone tell you that your symptoms are to be dismissed."

McLeod encourages people to keep seeking answers if one doctor won't listen. "Go to one doctor, then another, and another one, until someone listens to you," she said. "It literally will save your life."

From a scared mom facing late-stage cancer to a national advocate saving lives through awareness, McLeod proves that even our hardest battles can become our greatest gifts to others.
