( CNN ) -- Farrah Fawcett , whose public battle with anal cancer has brought new attention to a rarely discussed disease , has not been given a timetable from her doctor about how much time she has left , according to her friend Alana Stewart . Farrah Fawcett , seen here in 2006 , has waged a very public battle with anal cancer . `` No one has said to her you have two months to live , '' Stewart said Monday . `` So I 'm looking at that as a really good sign . '' Stewart talked with Lara Spencer , host of `` The Insider , '' who discussed her interview with Fawcett 's close friend on CNN 's `` Larry King Live '' Monday night . Spencer said Fawcett , her family and friends are clinging to hope for a recovery . `` She [ Alana Stewart ] does n't want to throw out a number . And neither does Farrah . ... They 're still hoping for that miracle , '' Spencer said . `` Farrah 's Story , '' a documentary-style program that has followed the course of her illness and showed her grueling treatment in graphic detail , aired on NBC Friday and was viewed by almost 9 million people . Fawcett and partner Ryan O'Neal watched the show together , Spencer confirmed . `` Alana said it was the ultimate in bittersweet , '' Spencer said . `` You know , they 're reliving two years of hell that they 've endured together . '' King asked Spencer whether Fawcett , who made her name a household word on the hit '70s TV series `` Charlie 's Angels , '' and O'Neal might marry . `` He said you never know . He was cagey about it , '' Spencer said . `` And , you know , I think he would in a second . He 's so madly in love with her . '' King also had a panel of medical experts on his show to discuss Fawcett 's cancer . Dr. Thomas Vogl , who at one time treated the actress in Germany , called her medical condition `` very , very serious . '' Dr. Allyson Ocean , a medical oncologist in New York , said only about 5,000 cases of anal cancer are diagnosed in the United States yearly . Unlike Fawcett 's case , it usually does n't spread , and only about 10 to 15 percent of cases are advanced , Ocean said . Fawcett 's cancer , however , is in Stage 4 and has spread to her liver . Ocean said there are various causes of anal cancer . `` One of the causes is a virus called the human papilloma virus , which is a sexually transmitted virus . It seems to be more common in women , in general , outside of any viral infections . Smoking is actually a risk factor , '' she said . King asked Dr. Paul Song , a radiation oncologist , if he had seen Stage 4 cancer cured . `` Not with anal cancer . I have seen it with other GI malignancies such as rectal cancer , '' Song said . `` But anal cancer is a little bit more difficult to treat . '' Despite the bleak outlook , Song had praise for Fawcett and her documentary . `` I think one of the most powerful things that Miss Fawcett did in this documentary was give patients a sense of hope and to just show how she 's handled this with such courage and dignity , '' Song said . CNN 's Dr. Sanjay Gupta told King that doctors have to strike a delicate balance when they are caring for patients such as Fawcett . `` You have to be absolutely honest with patients , but , you know , you do n't want to strip away their hope and optimism , either . There are people , Larry , as you know , who beat the odds , '' Gupta said . Vogl told King he developed a close relationship with Fawcett during the time he treated her in Germany and expressed admiration for his one-time patient . `` From a lot of treatments and contact and communication , I think she is extremely special , an extremely brave person , '' he said .
