I am prone to speculate that the faster we run from biology, the harder it bites us. Some women today mature younger, postpone childbirth, finally have one highly prized child but skip breastfeeding, or omit childbearing altogether. We spend years fooling our bodies into thinking they're pregnant. Sometimes our bodies conceive, but mentally we doubt and dicker and thwart nature. Our bodies, ourselves, are marinating in estrogen and confused by our attempts to deny our own anatomy.
Cancer prevention focuses on avoiding alcohol, tobacco, sun exposure, and dietary fat.
Other variables are being studied. Should it strike, there are several methods of treating cancer. Choice of treatment depends on the type and location of the cancer, whether the disease has spread, the patient's age and general health, and other factors. Best odds of successful treatment accompany early detection. See you doctor for a breast exam regularly.
