What are the risk factors for breast cancer?

A risk factor is anything that affects your chance of getting a disease, such as cancer.
Different cancers have different risk factors. For example, exposing skin to strong
sunlight is a risk factor for skin cancer. Smoking is a risk factor for cancers of the lung, mouth, larynx (voice box), bladder, kidney, and several other organs.

But risk factors don't tell us everything. Having a risk factor, or even several, does not mean that you will get the disease. Most women who have one or more breast cancer risk factors never develop the disease, while many women with breast cancer have no apparent risk factors (other than being a woman and growing older). Even when a woman with risk factors develops breast cancer, it is hard to know just how much these factors might have contributed.

Breast cancer: Do we know the causes ?

Many risk factors can increase your chance of developing breast cancer, but it is not yet

known exactly how some of these risk factors cause cells to become cancerous.

Hormones seem to play a role in many cases of breast cancer, but just how this happens is not fully understood.

DNA is the chemical in each of our cells that makes up our genes—the instructions for how our cells function. We usually look like our parents because they are the source of our DNA. But DNA affects more than how we look.

WHAT IS CANCER?

The body is made up of trillions of living cells. Normal body cells grow, divide into new
cells, and die in an orderly fashion. During the early years of a person's life, normal cells
divide faster to allow the person to grow. After the person becomes an adult, most cells
divide only to replace worn-out or dying cells or to repair injuries.
Cancer begins when cells in a part of the body start to grow out of control. There are
many kinds of cancer, but they all start because of out-of-control growth of abnormal
cells.

WHAT IS BREAST CANCER?

Breast cancer is a malignant tumor that starts in the cells of the breast. A malignant tumor
is a group of cancer cells that can grow into (invade) surrounding tissues or spread
(metastasize) to distant areas of the body. The disease occurs almost entirely in women,
but men can get it, too.
