"I will remain very much involved with my team and day-to-day operations here at UNC and expect to return to my sideline responsibilities as soon as possible," Hatchell said in a statement. "My veteran staff and team will be well prepared and meet any challenges until my return. Don't forget I am a Tar Heel woman!"
Hatchell, 61, was inducted into the Naismith Memorial Basketball Hall of Fame last month. She's preparing for her 28th season with the Tar Heels and has 908 career victories, making her one of only three head coaches in the sport to win 900 games.
Hatchell has led UNC to the 1994 NCAA championship, three Final Fours and eight Atlantic Coast Conference tournament championships.
Dr. Pete Voorhees, a medical oncologist at the Lineberger Cancer Center, will lead the team of doctors in charge of Hatchell’s treatment. Voorhees in a statement said Hatchell “remains strong and in good spirits.”
"Sylvia has our complete support and is in our thoughts and prayers for a full recovery," athletic director Bubba Cunningham said in a statement. "Sylvia is a fighter and her enduring spirit will aid her greatly."
Hatchell has received a ton of support from fellow coaches, such as former Tennessee head coach Pat Summitt and UNC men’s coach Roy Williams, as well wishers via twitter.
"I know how much Sylvia loves to coach and compete with her team so any time that she misses will be difficult," Williams said. "But she's tough and she will fight this with everything she has. All of us at Carolina and all of her friends in the coaching community will support her 100 percent in this fight."
Associate head coach Andrew Calder will lead the program while Hatchell is away. He has been on Hatchell's staff throughout her tenure, which includes six 30-win seasons.
In addition, former Campbell men's head coach Billy Lee will be added as an assistant coach on a temporary basis during Hatchell's absence. Lee has been the team's director of video and scouting, and special assistant to the head coach.
The Tar Heels, who went 29-7 and advance to the second round of the NCAA Tournament, lost their top two starters from last year. However, sophomore Xylina McDaniel (11.3 points, 7.1 rebounds) returns and UNC brought in a recruiting class ranked No. 1 nationally by ESPN HoopGurlz -- featuring McDonald's All-Americans Diamond DeShields, Stephanie Mavunga and Jessica Washington.
