The American Cancer Society has happily announced that cancer deaths have declined for the second straight year. This is big news -- mostly because our population is growing and aging and it's entirely possible this could have led to an increase in cancer deaths. Not only is this not true, but the drop in deaths for this second year is eight times greater than the drop during the first year. Amazing.

It's hard to imagine in light of this great news that there are still less hopeful statistics out there on the cancer front. But there are so many dimensions to this disease -- prevention, detection, diagnosis, treatment, survival -- that the numbers can vary tremendously depending on perspective.

From the perspective of diagnosis, one in two men and one in three women in America today will develop cancer during their lifetimes. These staggering statistics, based on data collected during 2001 through 2003, are detailed in a pivotal paper appearing in The Oncologist -- a monthly peer-reviewed journal for doctors devoted to cancer patient care.

Dr. Matthew Hayat and colleagues, who worked on this paper for the National Cancer Institute, reveal other worrisome numbers and facts.

It seems the number of new cancer patients is expected to more than double from the current 1.36 million in 2000 to almost 3 million in 2050. Five-year survival for all cancer stages combined ranges from as low as 16 percent for lung cancer patients to 100 percent for prostate cancer patients. And black Americans are reported to have the highest cancer incidence and mortality rates for men and women for all cancers combined.

So while less people are dying from cancer, diagnosis of the disease seems to be on the rise. Not exactly a perfect scenario -- but if science and research can keep up, perhaps those diagnosed with cancer will need to prepare not for death, but for the management of a chronic condition.

Technology has come a long way over the years -- and now the technology behind digital mammography is allowing life-saving screenings for the toughest patients to diagnose with breast cancer.

This is no small technological breakthough. It is a critical component for lowering the breast cancer death rate the American Cancer Society reports has declined 2.3 percent each year between 1990 and 2002. Since breast cancer is a treatable disease if caught early, digital mammography will up the odds of survival for women with this disease.

Digital mammography operates according to a computer-based technique that allows for digital manipulation of a breast X-ray. It exceeds the capability of film mammography -- and is much like the comparison between digital photography versus film photography. Both work. But one works better.

Studies show digital mammograms have a lot to offer. They detect tumors better in young women with dense breast tissue, for example. They allow for ease of storage and retrieval of images. And they can easily become part of a woman's electronic medical record.

There are still benefits of traditional mammography and women are still urged to use this less expensive option. They are also urged to conduct self-breast exams and to report for clinical exams with physicians. It's the whole package that contributes to comprehensive breast health, not just one isolated test. When used in combination with all other screening methods, digital mammography makes for a more accurate overall picture.

Cervical cancer is the second leading cause of cancer deaths among women worldwide. The World Health Organization has estimated that each year over 500,000 women will be diagnosed with cervical cancer and over 300,000 women will die of the disease. Cervical cancer is caused by a chronic infection with high-risk subtypes of the human papillomavirus (HPV). Two of these high-risk subtypes cause more than sixty percent of cervical cancers globally.

The impact of the widespread adoption of the HPV vaccination in Mexico showed that it could potentially drop the cases of cervical cancer by 59 percent. They showed that the biggest impact would be to girls given the vaccination at the age of ten.

Dr. Adriana Bermudez, who is a professor of gynecologic oncology and vice president elect of the International Gynecologic Cancer Society, says "This study shows the potential impact of the new prophylactic HPV vaccines in the Americas. We will need a major public-private partnership to make these vaccines available to the girls and women of the Americas, as well as a major educational campaign to alert parents to the importance of protecting their daughters from cervical cancer."

The International Gynecologic Cancer Society is a non-profit professional society with 1200 members from 80 countries dedicated to reducing the global burden of women's cancers through education and research.
