BUTTE, Mont. -

A Butte family told NBC Montana they want Mairissa Peoples to be remembered as a woman involved in the community who shared her story many times. 23-year-old Peoples passed away this week after a 7-year battle with cancer.

Her family said she was diagnosed her junior year of high school and because she was sick, Marissa spent a lot of her time at the Seattle Children's Hospital.

When Marissa found out she has to miss her junior prom, she and the nurses decided to hold a prom at the hospital. The community donated dresses for the children and makeup artists and photographers covered the event for free. It was just one of the ways Mairissa tried to touch the lives of everyone around her.

"Well you could describe her a lot of ways, but what comes up right to it, she was just a beautiful person and she touched so many lives," said Mairissa's grandfather, Don Peoples Sr.

"Just how proud I am that I got to be her mom and bring her into the world and her to leave the mark that she has left," said Mairissa's mother, Barb Peoples.

After high school, Peoples attended the University of Montana. She organized the Relay for Life event and gave inspirational speeches to the Montana Grizzly football team, Watch program, and others.

Mairissa's family says they plan to honor her by helping others who are fighting cancer.
