"As a practicing medical oncologist, I meet with patients and families every day to help manage their course through this disease called cancer. This experience provides unique insight into the needs of cancer patients, their families and loved ones and brings into sharp focus the need for reliable information to be readily available in terms that can be easily understood." — Dr. Timothy Moynihan
Dr. Timothy Moynihan believes that providing consumers accurate, timely information on the broad, complex topic of cancer is the biggest challenge facing medical Web sites. As the guiding force behind our cancer coverage, he makes sure Mayo Clinic meets the test.
Dr. Moynihan, born in Las Vegas, N.M., but raised in Denver, is a consultant in medical oncology at Mayo Clinic and an associate professor at Mayo Clinic College of Medicine. He is board certified in internal medicine, medical oncology, and hospice and palliative care medicine. He did his medical oncology training at Johns Hopkins Hospital in Baltimore, and then went on to the University of Minnesota and St. Paul Regions Medical Center in St. Paul, Minn., for seven years before moving to Mayo Clinic in 1999. Dr. Moynihan is director of the palliative care program at Mayo Clinic and associate medical director of the Mayo Clinic hospice.
Dr. Moynihan currently serves as the education chair for the Department of Medical Oncology and fellowship program director. Four times he has been selected as Teacher of the Year in medical oncology and elected to the Teacher of the Year Hall of Fame. Past honors include distinguished clinical teacher at the University of Minnesota Medical School, best internist at the Medical College of Wisconsin and recipient of The Upjohn Achievement Award for Excellence in Medicine. He serves on several national committees for the American Society of Clinical Oncology.
"The Internet provides a ready source of information on a wide range of topics of interest to those affected by cancer," Dr. Moynihan says. "The difficulty is trying to decide which sites provide reputable information and which information is relevant to each individual patient. The long history and tradition of excellence associated with Mayo Clinic assures you that information provided will be reliable, up-to-date and comprehensive."

Question
Atypical cells: Are they cancer?
Do atypical cells usually mean cancer?
Answer
from Timothy Moynihan, M.D.
Atypical cells appear abnormal, but they aren't necessarily cancerous. Many factors can make normal cells appear atypical, including inflammation and infection. Even normal aging can make cells appear abnormal.
Atypical cells can revert to normal if the underlying cause is removed or resolved. In some cases this happens spontaneously. In other cases, it's the result of a specific treatment.
Although atypical cells don't necessarily mean cancer, it's important to remember that some cancers first appear as atypical cells. If your doctor identifies atypical cells, close follow-up is essential. In some cases, the doctor may simply monitor the atypical cells to make sure they don't become more abnormal. In other cases, the doctor may recommend a particular treatment to try to reverse the process that's causing the atypical cells. And sometimes, the doctor may need to obtain a larger sample of tissue — such as a biopsy — to make sure cancer or another more serious condition isn't present.
