Breast Cancer: Early Detection

Why is it important to find breast cancer early?

Breast cancer is the most common cancer in women in the US. It is also a leading cause of death. With regular checks of the breast, most cancers can be found at an early stage, before they spread to other parts of the body. This is very important because when breast cancer is found early, before it spreads, it can be cured.

Some women have a higher risk than others, but any woman can get breast cancer. All women should be alert and check their breasts regularly.

What are the best ways to detect breast cancer early?

You can do 3 things:

• Do monthly breast self-exams of your breasts.
• Have regular medical checkups that include a check of your breasts by your healthcare provider.
• Have regular mammograms, according to your provider's recommendations. Some women who have a higher risk of breast cancer may also need to be screened with magnetic resonance imaging (MRI).

Breast self-examination

Breast self-exams should be done once a month. Do it at about the same time each month.

1. Lie down and put your left arm under your head. This spreads the breast tissue more evenly on your chest. Use your right hand to examine your left breast. With your 3 middle fingers flat, move gently in a small circular motion over the entire area of the breast, checking for any lump, hard knot, or thickening. Use different levels of pressure--light, medium, and firm--to feel breast tissue at different levels in your breast. Then put your right arm under your head. Use your left hand to examine your right breast in the same way you checked your left breast. Be sure to check the whole breast, from your collar bone above your breast and down until you feel only ribs below your breast.
2. Look at your breasts while standing in front of a mirror with your hands pressing firmly down on your hips. Look for lumps, new differences in size and shape, and swelling or dimpling of the skin.
3. While standing or sitting, slightly raise one arm, then the other, so you can check your underarm area for lumps.
4. Squeeze the nipple of each breast gently between your thumb and index finger. Report any discharge or fluid to your healthcare provider right away.

If you want to check to see if you are doing the exam the right way, ask your healthcare provider to show you how to do it.

Exams by your healthcare provider

Ask for yearly breast exams by your healthcare provider. Your provider can identify lumps the size of a pea, smaller than a woman can typically find on her own. In addition, a trained examiner can find lumps that are located in areas that are hard for a mammogram to detect, such as near the chest wall.

If you notice a lump in your breast, have it examined by your provider right away.

Mammograms

A mammogram is a special X-ray of the breast. It can show abnormalities that are too small to feel, so it is an excellent way to screen women for early breast cancer. However, although mammograms show most breast cancers, they do not find all cancers. Because of this, breast self-exams and physical exams by your provider are very important. These exams may find cancers that do not show on the mammogram and cancers that develop between mammograms.

All women age 50 to 70 should have a mammogram every 1 to 2 years, depending on their personal and family history. Comparing mammograms from year to year helps detect early cancer. If you are over 70, ask your healthcare provider how often you should have a mammogram.

If you are told that your mammogram is abnormal or that there are changes from your last mammogram, do not panic. It may be just normal tissue, but you will need to have it checked further. This may be done with more mammogram images, MRI, ultrasound, or a needle biopsy, depending on the opinion of the radiologist.

Remember, early detection is your best defense against cancer.
