Risk of Breast Cancer

The term “risk” is used to refer to a number or percentage that describes how likely a certain event is to occur.
When we talk about factors that can increase or decrease the risk of developing breast cancer, either for the first time or as a recurrence, we often talk about two different types of risk: absolute risk and relative risk.

Absolute risk

Absolute risk is used to describe an individual’s likelihood of developing breast cancer.
It is based on the number of people who will develop breast cancer within a certain time period. Absolute risk also can be stated as a percentage.

When we say that 1 in 8 women in the United States, or 13%, will develop breast cancer over the course of a lifetime, we are talking about absolute risk.

On average, an individual woman has a 1-in-8 chance of developing breast cancer over an 80-year lifespan.

The absolute risk of developing breast cancer during a particular decade of life is lower than 1 in 8. The younger you are, the lower the risk

Breast Cancer Risk

By now you may be familiar with the statistic that says 1 in 8 women will develop breast cancer. Many people misinterpret this to mean that, on any given day, they and the women they know have a 1-in-8 risk of developing the disease. That’s simply not true.
People tend to have very different ways of viewing risk. For you, a 1-in-8 lifetime risk may seem like a high likelihood of getting breast cancer. Or you may turn this around and reason that there is a 7-in-8, or 87.5%, chance you will never get breast cancer, even if you live to age 80. How you view risk often depends on your individual situation —
for example, whether you or many women you know have had breast cancer, or you have reason to believe you are at higher-than-normal risk for the disease — and your usual way of looking at the world.

Even though studies have found that women have a 13% lifetime risk of developing breast cancer, your individual risk may be higher or lower than that. Individual risk is affected by many different factors, such as family history, reproductive history, lifestyle, environment, and others.

This section is designed to help you better understand breast cancer risk and some of the factors that can increase risk.

symptoms

Breast Cancer symptoms

breast cancer may not cause any symptoms. A lump may be too small for you to feel or to cause any unusual changes you can notice on your own. Often, an abnormal area turns up on a screening mammogram (x-ray of the breast), which leads to further testing.

According to the American Cancer Society, any of the following unusual changes in the breast can be a symptom of breast cancer:

• swelling of all or part of the breast
• skin irritation or dimpling
• breast pain
• nipple pain or the nipple turning inward
• redness, scaliness, or thickening of the nipple or breast skin
• a nipple discharge other than breast milk
• a lump in the underarm area

These changes also can be signs of less serious conditions that are not cancerous, such as an infection or a cyst. It’s important to get any breast changes checked out promptly by a doctor.
