...Epstein-Barr virus, a member of the herpes family that is carried by an estimated 90% of American adults. Researchers speculate that stress, an immune-system deficiency or even environmental toxins could activate EBV, which is known to cause most cases of infectious mononucleosis and has been linked to Burkitt's lymphoma...
...severe sore throat during her tour and wondered if she had somehow passed along an infection that caused cancer. Poring over medical books in local libraries, they found no reference to a viral cause of non- Hodgkin's lymphoma. Instead, they came upon another cancer of immune-system cells, Burkitt's lymphoma, which afflicts black African children and is strongly associated with infection by the Epstein-Barr virus. Even though the stricken family is white, says the Georgia victim, "it was the only viral- caused cancer that we could find. Because of that and because of where our visitor came...
Confronting their doctors, the victims asked if they might have Burkitt's lymphoma, caught from their visiting aunt. A typical reaction, says the Georgian, was " 'Don't you ever say anything like that. If you came into my office and said that cancer is contagious, it would empty out.' " In desperation, a family member called Dr. Seymour Grufferman, a cancer epidemiologist at Duke University Medical Center, explained the contagion idea and sent him biopsy slides of the victims' tumors...
Grufferman too was skeptical -- until examination of the slides showed that one patient indeed had Burkitt's lymphoma. With Dr. Joseph Pagano, a cancer virologist at the University of North Carolina, Chapel Hill, he promptly launched an investigation.

The Epstein-Barr virus has been associated with a couple of types of cancer. In Central Africa and New Guinea, it has been linked to Burkitt's lymphoma, an immune-cell cancer that primarily strikes children. In southern China, the virus plays a role in nasopharyngeal carcinoma, a malignancy of the nose and throat that afflicts more than 50,000 people a year. Retroviruses are known to cause cancer in a wide range of animals, from...
