How to Check Your Breasts for Lumps and Changes

Checking your breasts means getting familiar with how they normally look and feel so you can spot changes early. The process takes about five minutes and involves two parts: looking in a mirror and feeling the tissue with your fingers. When breast cancer is caught while still localized, the five-year survival rate is 99.3%. When it’s caught after spreading to distant parts of the body, that number drops to 31%. Knowing your own baseline is one of the simplest things you can do to catch a change quickly.

What Guidelines Actually Recommend

The American Cancer Society no longer recommends a formal, scheduled breast self-exam as part of routine screening. Large studies found little evidence that structured self-exams reduce breast cancer deaths in women who also get regular mammograms. But the ACS is clear that this doesn’t mean you should never check. Their current position centers on “breast self-awareness”: know what’s normal for you and report any changes to a healthcare provider right away.

Some people still prefer a regular self-exam as a way to track what their breasts look and feel like over time, and that’s a reasonable approach. Think of it less as a screening test and more as building a mental map of your own body so that something new or different stands out.

When to Check

If you menstruate, the best time to check is a few days after your period ends. Hormone shifts during your cycle cause breast tissue to swell and feel lumpy or tender, which can make it harder to tell what’s normal. After your period, those hormonal effects settle down and the tissue is at its softest and least tender.

If you’re postmenopausal, pick a consistent day each month, like the first of the month, so it becomes a habit. If you’re pregnant, do the same: the first of each month works well. If you’re breastfeeding, check on a set day after you’ve nursed or pumped so your breasts are as empty as possible.

The Visual Check

Stand in front of a mirror with your top off and your arms at your sides. Look at both breasts for anything that looks different from last time. Then raise your arms overhead and look again. Finally, press your hands firmly on your hips and flex your chest muscles. Each position shifts the tissue slightly and can reveal changes that aren’t visible in other positions.

You’re looking for:

  • Skin changes like dimpling, puckering, or a texture that looks like orange peel
  • Swelling or distortion in the size or shape of either breast
  • Redness or flaky skin on the breast or around the nipple
  • Nipple changes such as a nipple that’s recently started pulling inward
  • Discharge from the nipple that happens on its own, especially if it’s bloody or clear

Most breasts are not perfectly symmetrical, and that’s normal. What you’re watching for is change from your own baseline, not perfection.

How to Feel Your Breasts

Lie down on your back. This position spreads the breast tissue more evenly across your chest, making it thinner and easier to feel through. Place one arm behind your head and use the opposite hand to examine that breast. Use the pads of your three middle fingers, not your fingertips.

Move your fingers in small, gentle circles about the size of a coin. At each spot, press at three different levels: light pressure to feel the tissue just beneath the skin, medium pressure to reach the tissue in the middle, and firm pressure to feel the tissue closest to your ribs and chest wall. Use all three pressures before moving to the next spot.

Cover the entire breast using a systematic pattern so you don’t miss any area. One approach is to move in vertical strips, starting at the outer edge near your armpit and working across the breast in straight lines, like mowing a lawn. Another is to imagine your breast divided into wedge-shaped sections like slices of pie and work through each wedge from the outer edge in toward the nipple. Either pattern works as long as you’re thorough.

The area you need to cover is larger than you might expect. Go from your collarbone down to the bottom of your breast, and from your armpit across to your breastbone. Breast tissue extends into the armpit, and lumps can appear there too. After finishing on your back, repeat the exam while standing or in the shower. Wet, soapy skin makes it easier for your fingers to glide and can help you notice subtle textures.

What Normal Feels Like

Breast tissue is naturally lumpy and uneven. It’s a mixture of fatty tissue, fibrous connective tissue, and glandular tissue, and the proportions vary from person to person. Younger people tend to have denser, lumpier tissue. After menopause, more of the tissue is replaced by fat, which generally feels softer. A firm ridge along the bottom curve of each breast is a normal structural feature.

The point isn’t to diagnose anything during a self-check. It’s to learn your particular landscape of lumps, ridges, and textures so that when something new appears, you notice it.

Changes Worth Reporting

The CDC lists these warning signs of breast cancer:

  • A new lump in the breast or underarm
  • Thickening or swelling of part of the breast
  • Irritation or dimpling of the skin
  • Redness or flaky skin on the nipple or breast
  • Pulling in of the nipple, or nipple pain
  • Nipple discharge other than breast milk, including blood
  • Any change in the size or shape of the breast
  • Pain in any area of the breast

Most breast lumps are not cancer. Cysts, fibroadenomas, and hormonal changes account for the majority of lumps that people find. But there’s no way to tell the difference by touch alone, so any new lump or persistent change deserves a professional evaluation.

What Happens If You Find Something

If you notice a change, your provider will start with a physical exam of your breasts, chest wall, underarms, and neck, both while you’re sitting up and lying down. From there, the next step is usually imaging. A diagnostic mammogram (an X-ray of the breast) and a focused ultrasound (which uses sound waves to see the tissue) are the most common first-line tests. An MRI is used less often and typically reserved for specific situations.

If imaging doesn’t explain the lump, the provider may recommend a biopsy, which means taking a small tissue sample for lab testing. This is the only definitive way to determine whether a lump is cancerous. The process from “I found something” to a clear answer usually moves fairly quickly, often within a few weeks, because providers prioritize new breast concerns.
