Breast Cancer, the 75 year perspective
In the era of "The Greatest Generation", the 1940's, only 72% of women diagnosed with Breast Cancer lived for five years. Today the five-year survival is 97%. This remarkable improvement in the results of treatment has several causes. Of significant importance is the education of women to pay attention to themselves. Regular self-examination of the breasts by women was previously strongly encouraged, but large studies have questioned the value of self-exam. It appears to result in more surgery with no influence on cancer mortality. A more modest goal of increased breast self-awareness has gained support recently. This personal awareness, along with increased public awareness of the issue has helped significantly.

A second reason for the improved statistics is the routine use of mammography. The American Cancer Society has recommended all women have a mammogram every year starting at age 45 and then every other year after age 55. This use of mammography means that the average size of the tumor detected is a fraction of what it was 50 years ago. These small tumors are much more easily treated.

The third reason for the improvement in Breast Cancer statistics is the treatment available to patients today. In the first half of the twentieth century the treatment for breast cancer was to remove the entire breast, the underlying muscles and all the lymph nodes in the armpit. The resulting wound was both ugly and in many cases disabling.

These women had difficulty using the arm afterward and often skin grafts were needed to close the large incisions. The patients were then treated with high doses of both radiation and chemotherapy, often with severe and unpleasant side effects. Since the 1980's, due to the small size of the tumors, many patients do not have the breast removed. Studies have shown that equal results can be obtained with simple removal of the cancer with a rim of normal tissue, followed by radiation of the remaining breast.

A sample of the lymph glands in the armpit is removed to determine if the cancer has spread outside the breast. Instead of the 5 to 7 day hospital stays of years gone by, the typical patient stays one night or less. Chemotherapy is still used but the improvements are remarkable. The drugs are far more specific for the tumor and the doses are adjusted to be effective without making the patient so ill. One, less toxic, treatment is an anti-estrogen drug such as Tamoxifen. These drugs block the female hormones that stimulate breast cancer growth, and are well tolerated even by elderly patients.

The future of breast cancer treatment may eventually lead away from surgery altogether. The development of specific medical treatment to kill or turn off cancer cells while leaving normal cells alone is the goal of many research efforts. The genetic mechanisms that change a normal cell into a cancer cell are becoming better understood and newer therapies designed to prevent that change may make breast cancer a rare problem someday.

For the present Breast Cancer remains a significant health problem. There are nearly 250,000 new cases in the United States every year. One out of every 8 women in Montana will develop breast cancer in her lifetime. Breast self-awareness and timely mammography remain the best hope for an early diagnosis. New developments in breast cancer treatment will aid in successful control of this common medical problem.

Women who have noticed a change in their breast or who haven't had a mammogram recently are encouraged to contact their personal doctor to have a mammogram ordered or to be seen.
