Watch This Marine Surprise the Mother He Hasn't Seen for Nearly Two Years During Her First Chemotherapy Counseling Session

One mother of seven received the surprise of a lifetime when the son that she had not seen for almost two years disguised himself as a doctor at her first chemotherapy counseling appointment this month.

After Toronto, Ohio, woman Mary Glasure, 59, was diagnosed with breast cancer a few weeks ago following several body scans and tests, she had prepared herself for even more "horrible news" as she walked into a room at the Tony Teramana Cancer Center March 16 to begin chemotherapy counseling, CBS News reported. Although most of her seven children were there at her side, one son, Marine Cpl. Corey Hoffmaster, was still in Yuma, Arizona, where he had been stationed for nearly two years — or so she thought.

As she sat and waited with her children, someone who appeared to be a doctor dressed up in blue scrubs and a surgical mask entered the room, saying, "I have a lunch appointment to get to; let's hurry up."

"I couldn't understand what he was saying to me. I was thinking: Oh my God, now what?" Glasure told CBS News.

In a video of the encounter, Glasure can be seen, confused, as she responded, "Uh, OK" to the "doctor" as she nervously chuckled and turned toward her children, throwing her hands in the air. But after she turned back around, the "doctor" pulled down his mask and she became instantly overcome with joy and sobs at the sight of her son.

"Hi, mama," Hoffmaster said in the video as he wraps his mother in a giant hug.

 "When he took his mask off, I just went nuts," Glasure told CBS News.

"I needed my spirits boosted," Glasure said to NBC's "Today." "It was once-in-a-lifetime thing for me. I never in a million years thought he would be coming back."

The video of the emotional reunion, which was filmed by another son, Cody Glasure, was posted to YouTube. Cody credits his sisters with coming up with the plan for their brother to surprise their mother with a visit in disguise, according to "Today."

"We were all in tears; it was pretty amazing," Cody told CBS News. "I'm still in shock that he did that. It was just a crazy and very emotional and amazing moment."
