Understand the disease to help ease some of the fear around it.
A breast cancer diagnosis comes with a lot of anxiety and worry. Learning what you can about the disease can help ease some of the fear it brings. Here's what you need to know about your risk of developing breast cancer, just how common it is, and more.
Does Breast Cancer Affect Just the Breasts?
Breast cancer encompasses diseases of the many types of tissues that make up the breast, with each type and cause of uncontrolled growth having its own prognosis and mode of treatment. Cancer is a disease of uncontrolled cell growth, so those cells can then invade areas near the breast (such as the lymph nodes under the arm) or other parts of the body (like the lungs, liver or brain).

How Common Is Breast Cancer?
Breast cancer is the second-most common cancer in women, according to the CDC. Almost one in eight women will develop cancer that invades surrounding tissues and requires treatment over the course of their life. While that number sounds frightening, the good news is that most women diagnosed with breast cancer will survive. While diagnoses have remained steady over the last decade, death rates from cancer have fallen and survival at five years has increased.
What Is My Risk of Developing Breast Cancer?
Simply being female and aging -- two things you can't control -- are the two biggest risk factors of developing breast cancer. But there are a variety of other risk factors too:
- Overweight or obesity, especially if weight is gained after menopause
- Lifestyle factors like physical inactivity or drinking more than one alcoholic drink per day
- Never having had children or having children after 30
- A previous history of breast cancer or radiation therapy to the chest
What About Genetics?
Most breast cancers are not genetic, even in cases where a woman might have a relative with a history of breast cancer. In the U.S., only 5-10% of breast cancers are hereditary. In some cases though, there is a genetic component. The BRCA1 and BRCA2 mutations are the best known and dramatically increase a woman's risk of developing breast cancer. However, these mutations are rare within the general population. Learn more about hereditary breast cancer here.
What Can I Do to Protect Myself?
While there's no sure way to avoid breast cancer, but there are a few things you can do to protect yourself. An important thing you can do is get mammogram screenings. Here's a rundown of the procedure and when you should start getting them -- and how often.
You should also do breast self-exams at home. Click here to see the easy steps and what exactly to feel for.
What Is the Treatment for Breast Cancer?
Breast cancer can be treated effectively depending on the stage of the cancer when it's discovered. This is why screening is so important. The earlier a cancer is detected, the easier it is to treat. Because of the variability in cancer stage and type, exact treatments are decided on and individualized with help from a doctor. Treatment can range from hormonal therapy to surgery and radiation.
