5 Signs You Need a Mammogram

If you’re a woman in your 30s, 40s, or beyond, you may be wondering: When should I get a mammogram? While the answer depends on your age, personal risk, and family history, there are certain signs you shouldn’t ignore—no matter how old you are.

Most major health organizations recommend that women begin annual screening mammograms between ages 40–50, depending on risk factors. However, when you’re experiencing symptoms, you may need a diagnostic mammogram sooner.

Here are 5 signs that it’s time to schedule a mammogram—even if you’re under 40.

1. You Feel a New Lump

A lump in your breast—or even in your armpit—could be a warning sign. While not all lumps are cancerous, only imaging or a biopsy can rule out something serious. Contact your doctor right away if you detect a lump that wasn’t there before.

2. One Breast Changes Size or Shape

Breasts may naturally change over time, but sudden changes in one breast (such as swelling, asymmetry, or distortion) could indicate an underlying issue. If one breast looks or feels different, ask your provider about getting a mammogram.

3. Nipple Discharge or Changes

If you’re not breastfeeding, there should be no discharge from your nipples. Bloody, milky, or clear discharge—especially from just one nipple—is a red flag. Other concerning symptoms include inverted nipples, scaling skin, or unusual redness.

4. Persistent Breast Pain or Swelling

Mild pain before your period is common, but ongoing breast pain or unexplained swelling shouldn’t be ignored. Even without a lump, pain or tenderness can sometimes be linked to early-stage breast cancer.

5. Skin Changes or Dimpling

Redness, irritation, or dimpling of the skin (resembling an orange peel) could signal inflammatory breast cancer. Any change to the skin’s texture on your breast should be examined by a doctor as soon as possible.
