When New England Patriots quarterback Tom Brady won the Super Bowl in 2017, his mother, Galynn, was battling breast cancer. But this year, she was able to celebrate her son’s sixth championship win cancer-free.

In 2016, Galynn was diagnosed with an aggressive form of breast cancer.

“I just remember sitting in the doctor’s office and them telling me, you know, ‘You have breast cancer,” Galynn told NFL 360 in 2017. (You can view the interview above.)

She underwent two lumpectomies, chemotherapy and radiation. Although her treatment caused her to miss Brady’s games, she watched on television every Sunday.

“He wanted to know what was happening,” said Tom Brady Sr. “He was in touch with us on an extraordinarily regular basis.”

Galynn’s last chemo treatment ended two weeks before Super Bowl LII, but she wasn’t cleared to travel to the big game until just one day before her scheduled departure. “I put my mask on, got on the airplane and decided to go,” she said. “I just wanted to be there for Tommy.”

Even with her completed rounds of chemotherapy and five weeks of radiation, Galynn’s type of cancer had a high risk of recurrence. So she was screened every three months.

In August 2017, her scan showed no signs of cancer.

On Sunday, following his Super Bowl LIII win, Brady posted an Instagram photo with his family. Galynn could be seen next to her son.

Brady gave an update on his mom in August.

“She’s doing really well,” he told WEEI Radio’s Kirk and Callahan, reported 24/7 Sports. “She gets her scans I think every three months, and she’s really done well. It’s been a while since she finished her treatments.”

He continued, “We’re always kind of praying and hoping they come back clean. So far they have, and we’re very blessed. It’s touched our lives, and it’s touched my mom’s life, and it gives you perspective on life when you go through those things. I think we’re very thankful for all the people who supported her and for all the people that are doing great work in the world.”
