Aretha Franklin  is battling cancer, according to reports from Detroit.
Fox 2 News  says a close relative of the 68-year-old singer has confirmed the diagnosis, while another relative reportedly told the station that the family is "very concerned."
While neither source disclosed what kind of cancer Franklin has, the Detroit News  cites another person familiar with the situation who says that Franklin has pancreatic cancer. A representative for Franklin did not respond to a request for comment at press time.
After being admitted to a Detroit hospital in late October for undisclosed reasons, Franklin announced in November that she would be cancelling all of her appearances  through May 2011 "at the insistence" of her doctors. Last week, she underwent surgery for undisclosed reasons and released a statement saying that the procedure was "highly successful." 
Rev. Jesse Jackson visited Franklin shortly after the surgery and told the Detroit News  that she was "recovering, and her sprirts are high. She's doing very well. She's very prayerful. She's a woman of deep religious faith."
