Cancer survivors band together to inspire others to keep fighting. 

Staten Island University Hospital hosted its "Knock out Cancer" event Sunday at the Hilton Garden Inn. 

The annual celebration marks National Cancer Survivors Day, honoring those with a history of the disease. 

Eighty Staten Islanders who are now in remission attended the event. 

They shared their stories of survival to help others get through the same battle. 

National Cancer Survivors Day is observed on the first Sunday in June each year.
