Fewer women are getting mammograms. Facilities offering mammograms are closing. Mammogram machine usage is declining. And we don't really know why.

"We're heading in the wrong direction," says Carol Lee, professor of radiology at Yale University School of Medicine and chair of the American College of Radiology's commission on breast imaging.

"If this decline holds up, it will be very worrisome," she says.

"We're looking at a possible increase in deaths if we see this continue," according to Diana Balma, vice president of public policy at Susan G. Komen for the Cure.

Studies don't show which women -- rich or poor, young or old, educated or uneducated -- are skipping these critical screenings, but there are a few possible reasons for this dangerous drop.

Think about this:

Perhaps there are fewer facilities, staffed by fewer radiologists and technologists due to high lawsuit rates and modest reimbursement. This is scary -- because the number of women old enough to get screened is increasing.

Women may be missing out on all sorts of necessary medical care because of inadequate health insurance or other access problems.

Women may be choosing, for whatever reasons, not to get mammograms, despite strong public urging that women age 40 and older get screened one time every year.

And now think about this:

Recent news about declining breast cancer rates may not be all that good. It may not be that fewer women are developing breast cancer. It may simply be that fewer women are getting early diagnoses because of irregular or nonexistent screening.

In the United States, mammograms are not recommended for women under the age of 40. Other then an annual check-up and a monthly self breast exam, young women with no family history of breast cancer have no medical tools available for preventing and detecting the disease. But no woman is immune to this disease -- and being female is the single most important risk factor for diagnosis. And young women do get breast cancer. I did. And so did Sharon Rutherford, a 36-year-old Ulster woman who was diagnosed in December.

Rutherford is urging health officials to lower the age for screening in Northern Ireland -- where routine breast screening programs are reserved for women between the ages of 50 and 64. Rutherford says this is inadequate as there is an "absolutely chronic" number of younger women suffering from breast cancer.

Although there is a reduced-age screening program that monitors women beginning at age 40, Rutherford would like to see the screening age reduced to 30. Until then, she is educating women about how they can be vigilant about their own care. She urges women to report to doctors anything that just doesn't feel right. And because doctors may excuse symptoms because women are "too young" for breast cancer -- that's what doctors told her -- women must aggressively pursue medical care. Rutherford kept pursuing the thickening she felt in her breast -- and eventually she was referred for screening.

Rutherford has had a partial mastectomy, chemotherapy, and radiation treatment. And she is now active in the Ulster Cancer Foundation's new support group -- specifically for women under the age of 40.
