What is Breast Cancer?

Breast cancer is a disease where abnormal cells in the breast grow out of control and form tumors. These tumors can spread throughout the body in nearby lymph nodes or other organs.

How Common is Breast Cancer?

Breast cancer is the second leading cause of cancer death among women. In 2020, about 2.3 million women were diagnosed with breast cancer globally and it caused 685,000 deaths. Annually in the United States, about 240,000 women and 2,100 men are diagnosed with breast cancer, with 42,000 women and 500 men dying each year from it.

What Increases Risk of Breast Cancer?

There are various factors that can increase your risk of breast cancer. As only 0.5-1% of breast cancers occur in men, simply being a female is a major breast cancer risk factor.

Other factors include: reproductive history (e.g., age of menarche and age of first pregnancy), family history of breast cancer, obesity, history of radiation exposure, tobacco and alcohol use, age, and postmenopausal hormone therapy.

How Can You Reduce Your Risk?

Although many factors are out of your control (e.g., family history and age), there are some factors that you can influence. With most diseases, it is important to lead a healthy lifestyle. This includes being physically active, avoiding tobacco products, keeping a healthy weight, and only drinking alcohol in moderation or not at all.

It is also important to consult with your doctor about your individual risk and plan. For example, if your risk is higher than average, it may be necessary to start screening for breast cancer sooner/more frequently.

What Are Common Symptoms?

There are various symptoms of breast cancer to look out for. It is important to know how your breasts look and feel throughout the month so you notice when there are any changes. Symptoms can include:

  • change in appearance in the nipple and/or areola

  • change in breast size, shape, or appearance
  • a lump in the breast
  • dimpling, redness, or other changes in the skin of the breast

Because many people will not experience any symptoms when the cancer is still early, screenings are crucial for early detection.

There different types of breast cancer screenings. First and foremost, monthly self-exams are typically recommended so you can become familiar with how your breasts look and feel, as well as notice if there are any changes.

A Mammogram is an x-ray of the breast. The United States Preventive Services Task Force (USPSTF) recommends that 50-74 year old women who are at average risk of breast cancer get a mammogram every two years.

A Magnetic Resonance Imaging (MRI) takes images of the barest using magnets and radio waves. Doctors sometimes use MRIs along with mammograms for those at a higher risk of breast cancer.

How is Breast Cancer Treated?

Treatment for breast cancer varies and can depend on the kind of breast cancer and how far it has spread. Multiple treatment options may also be combined to minimize the chances of the cancer coming back. These treatment options include:

  • surgery
  • chemotherapy
  • radiation therapy

If a patient is diagnosed with breast cancer, a team of doctors will become involved. This may include a medical oncologist, a radiation oncologist, a surgeon, and more.

  1. Please include a diverse group of women picture in your reporting as women from different backgrounds and ethnicities are also affected by breast cancer.

    1. We do strive for inclusivity in our photography but are sometimes constrained by available photography. In this case, we wanted an image that included women with the Breast Cancer Awareness ribbon and this was the best available image.
