What Does a Lump in Your Breast Feel Like During a Breast Self-Exam?

Doing regular breast self-exams is one of the best ways to detect changes in your body and catch breast cancer early. But what does a lump in your breast actually feel like—and when is it something to be concerned about?

At BASS Medical Group, our Primary Care Providers and the team at the BASS Cancer Center are here to help you understand what’s normal, what’s not, and what steps to take if you find something unusual.

Is It Normal to Feel Lumps in Your Breast?

Yes—breast tissue naturally feels lumpy or rope-like, especially in people assigned female at birth. Hormonal changes during the menstrual cycle can also make the breasts feel more tender or dense.

However, some lumps stand out more than others and may feel:

• Firmer or harder than the rest of the tissue
• Round, oval, or irregular in shape
• Distinct from surrounding tissue
• Moveable (though some are fixed)
• Varying in size (from pea-sized to larger)

Most breast lumps are benign (non-cancerous), but any new or unusual lump should be evaluated by your doctor.

What Should You Do if You Find a Lump?

If you find a lump, don’t panic. Many are caused by cysts, fibrocystic changes, or hormonal shifts. However, you should schedule an appointment with your BASS Medical Group Primary Care Provider to be safe. They may refer you to the BASS Cancer Center for further testing, such as a mammogram, ultrasound, or biopsy.

Additional signs to watch for:

• Skin dimpling or puckering
• Nipple inversion or discharge
• Redness, swelling, or itching
• Pain that doesn’t resolve after your menstrual cycle
• Noticeable changes in lump size or texture

How to Perform a Breast Self-Exam (Step-by-Step)

You don’t need any special equipment—just a few minutes each month and a mirror.

1. Visual Inspection

Stand shirtless in front of a mirror with your arms at your sides. Look for:

• Size, shape, or symmetry changes
• Skin dimpling, puckering, or redness
• Changes to the nipple (like inversion or discharge)

Repeat this with your arms raised overhead and again with hands pressed on your hips.

2. Physical Exam (In Shower or Lying Down)

• Use the pads of your fingers and move in small circular motions
• Cover the entire breast, including the outer edges and underarm
• Use light, medium, and firm pressure
• Check both breasts for symmetry or irregularities

Do this once a month, preferably a few days after your menstrual cycle ends when breasts are least tender.

When to See a Doctor

Make an appointment if you:

• Discover a new lump or noticeable change
• Have nipple discharge, pain, or swelling
• Have a family history of breast cancer
• Are over 40 and haven’t had a recent mammogram
