When I describe the cancerous lump I found in my breast almost three Novembers ago, I explain that it felt like a hard, frozen green pea. The port used for chemotherapy infusions and sewn under the skin near my collarbone? It looked like a bottle cap popping up for all to see. My kids called it a stone. I had to numb my skin prior to treatments -- the needle inserted into the center of the port was just too big and painful. I slathered on my numbing lotion prior to each dose of drugs. Imagine the size of a quarter. I used twice this much. I was wimpy.

There's something about visual descriptions that help us remember some of the more important things in life. Here's a good one:

According to Jeffrey Dover, MD and associate clinical professor of dermatology at Yale School of Medicine, we must not skimp when we apply sunscreen. How do we know if we are cutting ourselves short? We should be using a shot-glass full of sun protection to cover our bodies. Anything less is not enough.

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.
