A Kansas father got a tattoo identical to the scar from his son’s brain surgery after the 8-year-old admitted it made him feel like a “monster.”

Gabriel Marshall was diagnosed with a rare brain tumor called anaplastic astrocytoma in March of 2015, according to Buzzfeed. He underwent surgery and has been off of treatment for the past nine months, his father Josh Marshall, 28, said.

“My son was very self-conscious after he got his surgery. He felt like a monster,” Josh Marshall told ABC news.

“This broke my heart. ... I told him if people wanted to stare, they could stare at both of us,” Josh Marshall told Buzzfeed.

In honor of Father’s Day, Josh Marshall entered St. Baldrick’s Foundation’s #BestBaldDad competition by submitting the photo of his tattoo matching Gabriel’s surgery scar. The photo was captioned: “Me and my son at this year’s St. Baldrick’s event in Wichita, Kansas. Got my son’s scar tattooed to help his self confidence.”

After 55 photo submissions to the contest, St. Baldrick’s Foundation declared Josh Marshall as the winner on June 19. They received more than 5,000 votes.

St. Baldrick’s Foundation thanked those who participated in the contest. “And to all the dads who shave their heads to help kids with cancer, you all are our favorite #BestBaldDads.”
