How is breast cancer detected?

A screening mammogram is used to detect breast changes that could be cancerous in people who have no signs or symptoms. The goal is to detect cancer when it’s small and treatment may be less invasive.

Can Breast Cancer Risk be Controlled?

Scientists and doctors don’t know exactly what causes breast cancer, but they do know certain factors are linked to it. Some of these risk factors can be controlled and others cannot. So, while all women are considered at risk for the disease, experts at the American Cancer Society say that you may be able to lower your risk slightly by controlling the factors you can.

Risk Factors You Can Control

• Alcohol: If you consume one alcoholic drink a day, you are at a slightly increased risk for breast cancer. If you consume two to five alcoholic drinks a day, you are at 1 1/2 times the risk.
• Birth control pills: You are at a slightly higher risk of breast cancer if you are using birth control pills. If you stopped using the pills more than 10 years ago, you have no increased risk.
• Breastfeeding: Breastfeeding will slightly lower your breast cancer risk, especially if it lasts a total of two years.
• Weight: Following menopause, carrying excess weight can put you at a slightly higher risk for breast cancer. This is especially true if your extra weight is in the waist, and if you gained the weight in adulthood.
• Exercise: If you exercised as a youth, you may have a life-long reduced risk of breast cancer. If you exercise even a small amount as an adult, you lower your risk.
• Hormone replacement therapy: If you’ve used hormone replacement therapy for relief of menopause symptoms for more than five years, you’re at a slightly increased risk of breast cancer. If you stopped hormone replacement therapy five or more years ago, your risk is reduced.

Risk Factors You Cannot Control

• Age: Your chance of developing breast cancer goes up as you age.
• Family history: Your risk for breast cancer is higher if you have blood relatives who have had the disease.
• Genetic factors: If you have inherited a mutated gene from either parent, you are more likely to get breast cancer.
• Menstrual periods: If you began having your periods before the age of 12 or went through menopause after 55, you have a slightly increased risk of breast cancer. If you have not had children or had your first child after the age of 30, you are at a slightly increased risk.
• Personal history: If you have cancer in one breast, you have a greater chance of getting it in the other or in another part of the same breast.
• Race: If you are Caucasian, you are more likely to develop breast cancer than if you are African American. If you are Asian, Hispanic or American Indian, your risk is lower.

Signs and Symptoms

According to the American Cancer Society, the most common sign that you may have breast cancer is a new lump in your breast. The lump is more likely to be cancerous if it’s painless, hard, and has uneven edges, but some rare cancers are tender, soft and rounded.

Other signs of breast cancer include:

• A lump in your underarm area
• Swelling of part of your breast
• Skin irritation or dimpling
• Nipple discharge other than breast milk
• Nipple pain or your nipple turning inward
• Redness or scaliness of your nipple or breast skin

It’s important to have anything unusual checked by your doctor. If your doctor suspects that you have cancer, you’ll need more testing. If you are diagnosed with breast cancer, the American Cancer Society suggests that that you give yourself time to adequately learn about the disease and your treatment options.

Early Detection

Early detection is the best and most effective tool in the battle against breast cancer. According to the American Cancer Society, there are more than two million breast cancer survivors in the United States. Understanding your risk factors and making wise lifestyle choices is the first step. Regular check-ups and screenings are important, too – the earlier breast cancer is found, the better your chances for successful treatment and recovery. Mammograms play a key role in monitoring your breast health and detecting any changes that warrant further examination.
