World Cancer Day means hope, courage and inspiration for cancer patients, caregivers, survivors and supporters.

The annual advocacy day is observed Feb. 4 with events, campaigns and messages that raise awareness about the disease and funds to find a cure.

The day is also an opportunity to share stories of resilience and hope.

Two-time cancer survivor Sean Swarner is one such story. He ran the Boston Marathon after being told by a doctor earlier that he had only two weeks to live, American Way magazine reports.

"I think I had two choices. It was either to fight for my life or give up and die, and I just don't think I was ready to give up," he told WTNH.

And some of the youngest survivors have given back the most.

In April, Leland Camara, a 5-year-old battling leukemia, decided to use one of his wishes from the Make-A-Wish Foundation to feed children in need in his Anchorage, Alaska, community, he told kls.com.

"When I asked him if he was sure he wants to serve other kids, he says, ‘So many people helped me so I want to help others,'" Laure Bruce of the Make-A-Wish Foundation told kls.com.
