Breast Self-Exam Instructions
Just after your period ends (or at the same time each month if you no longer have periods) perform your self-exam. You are looking for any changes in your normal look and feel of your breasts. Report any changes to your doctor. One way women can be familiar with
your breasts is through breast self-examination.
Breast self-exams should begin monthly starting at age 20.
Step 1 - While Lying Down
- Lie down and place your right arm behind your head.The exam is done while lying down, and not standing up. This is because when lying down the breast tissue spreads evenly over the chest wall and it is as thin as possible, making it much easier to feel all the breast tissue.
- Use the finger pads of the three middle fingers on your left hand to feel for lumps in the right breast. Use overlapping dime-sized circular motions of the finger pads to feel the breast tissue.
- Use 3 different levels of pressure to feel all the breast tissue.
- Light pressure is needed to feel the tissue closest to the skin.
- Medium pressure to feel a little deeper.
- Firm pressure to feel the tissue closest to the chest and ribs.
- A firm ridge in the lower curve of each breast is normal. If you’re not sure how hard to press, talk with your doctor or nurse.
- Use each pressure level to feel the breast tissue before moving on to the next spot.
- Move around the breast in an up and down pattern starting at an imaginary line drawn straight down your side from the underarm and moving across the breast to the middle of the chest bone.(sternum or breastbone). Be sure to check the entire breast area going down until you feel only ribs and up to the neck or collar bone (clavicle).
- There is some evidence to suggest that the up and down pattern (sometimes called the vertical pattern) is the most effective pattern for covering the entire breast without missing any breast tissue.
- Repeat the exam on your left breast, using the finger pads of the right hand.
Step 2 - While Standing in Front of the Mirror
-
While standing in front of a mirror with your hands pressing firmly down on your hips, look at your breasts for any changes of size, shape, contour, dimpling, or redness or scaliness of the nipple or breast skin. (The pressing down on the hips position contracts the chest wall muscles and enhances any breast changes.)
-
Examine each underarm while sitting up or standing and with your arm only slightly raised so you can easily feel in this area. Raising your arm straight up tightens the tissue in this area and makes it difficult to examine.
This procedure for doing breast self-exam is different than previous procedure recommendations. These changes represent an extensive review of the medical literature and input from an expert advisory group. There is evidence that the woman's position (lying down), area felt, pattern of coverage of the breast, and use of different amounts of pressure increase the sensitivity of BSE as measured with silicone models. Lying down also made it easier to feel lumps while doing CBE using patient models with known small non-cancerous lumps in their breasts.
