Each year 185,000 U.S. women learn that they have breast cancer. Because less than a quarter of them have genetic or other known risk factors, the diagnosis often comes as a devastating surprise.

The emotional turmoil that results can affect a woman's physical health as well as her psychological well-being.

These questions and answers explain how psychological treatment can help such women harness the healing powers of their own minds.

What impact does a breast cancer diagnosis have on psychological well-being?

Receiving a diagnosis of breast cancer can be one of the most distressing events women ever experience. And women may not know where to turn for help.

Distress typically continues even after the initial shock of diagnosis has passed. As women begin what is often a lengthy treatment process, they may find themselves faced with new problems. They may find their personal relationships in turmoil, for instance. They may feel tired all the time. They may be very worried about their symptoms, treatment and mortality. They may face discrimination from employers or insurance companies. Factors like these can contribute to chronic stress, anxiety and depression.

Why is it important to seek psychological help?

Feeling overwhelmed is a perfectly normal response to a breast cancer diagnosis. But negative emotions can cause women to stop doing things that are good for them and start doing things that are bad for anyone, but especially worrisome for those with a serious disease. Women with breast cancer may start eating poorly, for instance, eating fewer meals and choosing foods of lower nutritional value. They may cut back on their exercise. They may have trouble getting a good night's sleep. And they may withdraw from family and friends. At the same time, these women may use alcohol, cigarettes, caffeine or other drugs in an attempt to soothe themselves.

A breast cancer diagnosis can also lead to more severe problems. Researchers estimate that anywhere from 20 to 60 percent of cancer patients experience depressive symptoms, which can make it more difficult for women to adjust, participate optimally in treatment activities and take advantage of whatever sources of social support are available. Some women become so disheartened by the ordeal of having cancer that they refuse to undergo surgery or simply stop going to radiation or chemotherapy appointments. As a result, they may get even sicker. In fact, studies show that missing as few as 15 percent of chemotherapy appointments results in significantly poorer outcomes.

How can psychological treatment help women adjust?

Licensed psychologists and other mental health professionals with experience in breast cancer treatment can help a great deal. Their primary goal is to help women learn how to cope with the physical, emotional and lifestyle changes associated with cancer as well as with medical treatments that can be painful and traumatic. For some women, the focus may be on how to explain their illness to their children or how to deal with a partner's response.

For others, it may be on how to choose the right hospital or medical treatment. For still others, it may be on how to control stress, anxiety or depression. By teaching patients problem-solving strategies in a supportive environment, psychologists help women work through their grief, fear and other emotions. For many women, this life-threatening crisis eventually proves to be an opportunity for life-enhancing personal growth.

Breast cancer patients themselves aren't the only ones who can benefit from psychological treatment. Psychologists often help spouses, who must offer both emotional and practical support while dealing with their own feelings, for instance. Children, parents and friends involved in caring for the patient can also benefit from psychological interventions.
