Breast cancer, the second-leading cause of cancer deaths in American women, is the disease women fear most. Experts predict 178,000 women will develop breast cancer in the United States in 2007. Breast cancer can also occur in men, but it’s far less common. For 2007, the predicted number of new breast cancers in men is 2,000. causes of breast cancer

Previous diagnosis of breast cancer

If you have had breast cancer before, you are more at risk of developing the condition in your other breast. If this is the case, you should be closely monitored by your treatment team, such as your oncologist (specialist in cancer) and your breast nurse, so that any recurring cancer can be detected as soon as possible.

Age and gender — Your risk of developing breast cancer increases as you get older. The majority of advanced breast cancer cases are found in women over age 50. Women are 100 times more likely to get breast cancer then men.

Even if the antiperspirant were concentrated in the armpit lymph nodes, the lymphatic fluid would not drain away to the breast. The direction of lymphatic fluid flow starts in the breast, and drains out through the armpit lymph nodes, toward the neck, and back into circulation. Additionally, there are one-way valves along the lymphatic drainage channels that keep the fluid moving in one direction (AWAY from the breast, not TO the breast).

The exact cause of breast cancer is not known. Female hormones and increasing age play a part. The chances that you will develop breast cancer increase as you age. In the United States, about 1 in every 8 women who live to be 80 will have been diagnosed with breast cancer at some point in her life.2

No one knows what causes breast cancer, and no one can clearly say why we are seeing an increase in breast cancer cases. More women develop breast cancer than men — about 100 cases in females for every one in a man. Women’s bodies make more estrogen than men’s. Therefore, the conventional wisdom has been that estrogen causes breast cancer.

Light pollution seems to have other untoward consequences, including harmful effects on animals like migratory birds and sea turtles. But the apparently carcinogenic effects of light pollution have received—and arguably deserve—the lion’s share of scientists’ attention. No one has paid more notice to the light-cancer connection than Richard Stevens, the University of Connecticut Health Center epidemiologist who first proposed a possible link more than two decades ago. Stevens collaborated on the new study with four colleagues in Israel, and I asked him to comment on its significance.
