Breast Self-Exam: How to Check for Breast Cancer Symptoms at Home

Performing a breast self-exam is a simple yet powerful tool in detecting early signs of breast cancer. While women over 40 are encouraged to get regular mammograms, younger women can take charge of their breast health at home.

Doing a self-exam monthly helps you understand what’s normal for your body—so if something changes, you’ll know.

Here’s how to perform a breast self-exam at home and what symptoms to watch for.

Step-by-Step Guide to a Breast Self-Exam

1. Look in the mirror.
Stand with your shoulders straight and arms on your hips. Look for any visible changes such as:

• Changes in breast size or shape
• Swelling, dimpling, or puckered skin
• Redness, rash, or inverted nipples

2. Raise your arms.
With your arms above your head, look again for the same signs. Check for:

• Skin changes
• Unusual swelling
• Nipple discharge (if not breastfeeding)

3. Lie down and feel for lumps.
Use your opposite hand to check each breast. Using the pads of your fingers:

• Move in a circular motion across the entire breast
• Apply light, medium, and firm pressure to feel all layers of tissue
• Don’t forget the armpit area and up to the collarbone

4. Repeat in the shower or while standing.
Many people find it easiest to do this part in the shower when the skin is slippery. Follow the same circular pattern and pressure technique.

Tip: Choose the same day each month to stay consistent.

What to Look for During a Breast Self-Exam

While it’s normal for breasts to feel a little lumpy, new or unusual changes should be reported to your doctor. Signs of possible breast cancer include:

• A new lump in the breast or underarm
• Thickening or swelling of part of the breast
• Redness, flaking, or irritation of the skin
• Nipple changes or discharge
• Persistent pain or tenderness

Even though these symptoms don’t always indicate breast cancer, it’s best to consult a doctor if you notice anything out of the ordinary.

When to See a Doctor for a Breast Lump

If you discover a new lump or see any of the above symptoms, schedule an appointment with your primary care provider or breast specialist. Depending on your findings, your doctor may recommend:

• A clinical breast exam
• A mammogram
• An ultrasound or breast MRI
• A biopsy if needed
