Her friend, Betty Slick, 73, of Hagerstown, is a nine-year colon cancer survivor. She said after beating cancer, she is no longer bothered by the "little things."
"You just want to be around positive people," Slick said.
Susan Lopp, administrative director of the John R. Marsh Cancer Center, said Sunday was the largest turnout in the picnic's history.
"People are surviving cancer longer," she said. "People come back every year."
Patti Koons, 78, of Halfway, said she is a 17-year survivor of colon cancer. After doctors removed 17 inches of her colon, the cancer never returned, she said.
Sunday was her first time at the picnic. Koons said she and her husband, George Koons, have stayed away in the past because they don't like to be around large crowds.
Dolores Kreps, 71, of Williamsport, was first diagnosed with breast cancer 23 years ago. The cancer returned for the third time late last year. She takes a small pill each day and said her health has improved.

Leslie Shirley, 77, of Hagerstown, said he is a five-year prostate cancer survivor. He was attending his first John R. Marsh Cancer Center picnic Sunday with his wife, Charlotte Shirley.

"You're never rid of it," he said.
Teresa Downs, 51, of Silver Spring, Md., said she was in town visiting her mother, Hagerstown resident Evelyn Downs, and they decided to attend the picnic together.
Teresa is a two-year survivor of breast cancer and has been undergoing chemotherapy since February. Her last treatment is Wednesday.
"Then I'll start radiation," she said.
Evelyn Downs said it has been hard to watch her daughter go through the grueling treatments.
"I'm being supportive," she said. "(Teresa's) doing fine."
Sigrid Byers, 64, of Hagerstown, has survived breast cancer for more than three years, and said she couldn't have done it without support from friends and family.
"She's been my angel," Byers said of her friend Emily Webster of Hagerstown.
Byers' husband died of lung cancer nearly two years ago. She said she has some advice for those in a similar situation.
"Have a lot of willpower," she said. "Believe in God. Lots of prayers. I love life. I want to live."
