A proper breast exam combines two techniques: looking for visible changes in a mirror and feeling the entire breast tissue using your fingertips at three different pressure levels. The whole process takes about 10 minutes and should ideally be done 7 to 10 days after your menstrual period starts, when breast tissue is least swollen and tender. If you no longer menstruate, pick the same day each month so you build a consistent baseline of what your breasts normally feel like.
Start With a Visual Check
Stand in front of a mirror with your arms at your sides and look at both breasts. You’re scanning for anything that looks different from the last time you checked. Raise your arms overhead and look again, then press your hands firmly on your hips to flex your chest muscles and look a third time. Each position shifts the breast tissue slightly, making certain changes easier to spot.
What you’re looking for:
- Dimpling or puckering: Small indentations in the skin that weren’t there before, sometimes making the surface look like orange peel
- Color changes: Patches of red, pink, or purple skin on any part of the breast
- Texture changes: Skin that looks rough, scaly, or uneven
- Shape or size changes: One breast noticeably different from how it looked previously
- Nipple changes: A nipple that has started turning inward, or any spontaneous discharge or bleeding
Most people have some natural asymmetry between their breasts. You’re not comparing left to right so much as comparing each breast to how it looked last month.
How to Feel Your Breast Tissue
Use the pads of your three middle fingers, not the tips. The pads are the flat part of your fingertips and can detect subtle differences in tissue far better than poking with your fingertip ends. Keep your fingers flat and together as you press.
The most effective pattern, based on clinical evidence from Stanford Medicine, is the vertical strip method, sometimes called the “lawnmower” pattern. Starting at the outer edge of your breast near your armpit, move your fingers up and down in a straight vertical line. When you reach the bottom, shift over about a finger-width and move back up. Continue this back-and-forth pattern across the entire breast, from the armpit to the center of your chest. This systematic approach ensures you don’t skip any areas, which is the most common mistake people make.
At each spot, press at three distinct levels of pressure before moving on:
- Light pressure feels the tissue just beneath the skin
- Medium pressure reaches the middle layers of breast tissue
- Firm pressure presses down to the tissue closest to the chest wall and ribs
With firm pressure, you should be able to feel your ribs. If you can’t, press harder. Many people use too little pressure because they’re afraid of hurting themselves, but breast tissue can handle firm touch without damage.
Why Position Matters
Do the palpation in two positions: standing up (or in the shower, where wet skin helps fingers glide) and lying down. When you lie flat, breast tissue spreads more evenly across the chest wall, making it thinner and easier to examine thoroughly. Deeper tissue that’s harder to assess while standing becomes more accessible.
When lying down, place a pillow under the shoulder on the side you’re examining and raise that arm above your head. This spreads the tissue even further. Use your opposite hand to do the exam. Don’t forget to check the area extending up into the armpit, where breast tissue and lymph nodes are present.
What Normal Tissue Feels Like
Breast tissue is naturally lumpy and uneven. The upper outer area near the armpit tends to be the firmest and most textured. The tissue beneath and around the nipple often feels grainier. You may notice areas that feel like a chain of small bumps, which is typical glandular tissue. This is why doing the exam monthly matters: you learn your own normal texture and can detect when something actually changes.
Fibrocystic breast changes are extremely common, especially in the days before a period. Breasts may feel swollen, lumpy, or sore, then return to normal afterward. This is not a sign of disease. It’s also why timing the exam to a week after your period starts gives you the most reliable baseline.
What Should Raise Concern
Not every lump is cause for alarm. Fibroadenomas, the most common benign breast lumps, are smooth, rubbery, and move freely when you push them. Cysts are fluid-filled and usually feel soft, though deeper ones can feel firmer. Lipomas are soft fatty lumps that also slide around under your fingers.
A lump that’s more concerning typically has a different set of characteristics. As one breast surgeon at Mass General Brigham describes it, a tumor feels more like a rock than a grape. It’s usually hard rather than squishy, has irregular or angular edges rather than smooth ones, and tends to stay fixed in place when you press on it instead of moving freely. A lump that doesn’t go away after your next menstrual cycle, or that seems to be growing, warrants medical attention.
Other changes worth getting checked include skin dimpling or puckering that develops between exams, persistent redness, nipple discharge (especially if it’s bloody or comes from only one breast), or a noticeable change in breast shape.
What Happens if You Find Something
The first step is usually a diagnostic mammogram, which is a more detailed X-ray than a routine screening mammogram, focused on the specific area of concern. Your doctor may also order an ultrasound, which uses sound waves to determine whether a lump is solid or fluid-filled. Cysts filled with fluid are almost always benign. Solid masses need further evaluation.
In some cases, an MRI provides additional detail. If imaging suggests something suspicious, a biopsy removes a small sample of tissue for examination under a microscope. This is the only test that can definitively determine whether a lump is cancerous. The vast majority of lumps that get biopsied turn out to be benign.
Breast Exams for Men
Male breast cancer is uncommon, but it does occur. Men have a small amount of breast tissue behind the nipple, and the self-exam technique is the same: use your fingertips to feel the chest area for lumps or thickening, and visually check for skin changes, nipple discharge, or scaling.
Men with a known genetic risk factor for breast cancer, such as a BRCA2 mutation, should become familiar with the normal feel of their chest tissue and check regularly. If you’ve had gender-affirming chest surgery, a small amount of breast tissue typically remains, so periodic self-checks still apply. Any new lump, skin dimpling, nipple discharge, or change in how the area looks or feels is worth reporting to your doctor.
