Boy With Cancer Gets Boost From Superheros at Early Halloween Party

— -- The parents of a 5-year-old are hoping his last months alive will be filled with happy experiences.

Chris and Kelen Lee threw their son, Billy Lee, an early Halloween party on Saturday, and recently took him on a trip to Florida theme parks.

“He’s different than he was 10 months ago. He’s happy. It makes us happy to see him smile,” Chris Lee told ABC affiliate KTRK.

“That’s the point of everything we do,” he added.

Billy was diagnosed with medulloblastoma -- a form of brain cancer -- two years ago and went through four surgeries and chemotherapy before doctors determined the cancer became untreatable, KTRK reported.

Billy is believed to have a little more than a month left to live, so his parents, neighbors and strangers brought Billy Halloween, his favorite holiday a few months early. Billy wore an Iron Man costume at his Avengers-themed party, which was complete with cake and decorations.

“We could continue the chemotherapy for an extra two months, but what is the meaning? You get an extra two months if you need to stay in the hospital for three days?” Kelen Lee told KTRK.

The family recently got back from a two-week Florida vacation, where Billy got to meet his favorite characters at the theme parks, according to the family’s GoFundMe page.

Family, friends and complete strangers have donated more than $26,000 to the family through the GoFundMe page in the past month. ABC News' efforts to reach the family through the GoFundMe page were not immediately successful.

Because of the donations, the Lees were able to take a break from their jobs and enjoy the moments they have left as a family, KTRK reported.

Medulloblastoma is the most common brain cancer in children, according to the Mayo Clinic.
