This is what most people think of first. A lump in the breast or underarm area.

What it can feel like: Hard, painless, with irregular edges. Or soft, tender, and smooth. Not all breast cancer lumps are hard and painless.

What to do: Any new lump—especially one that doesn’t go away after your period—should be evaluated by a doctor. Most lumps are benign, but they all deserve attention.

2. Skin Dimpling or Puckering

This is the sign I had. A small indentation that looks like the skin of an orange (peau d’orange).

What it looks like: Dimpling, puckering, or a texture that resembles an orange peel. May be more visible when you raise your arm or bend forward.

Why it happens: A tumor can pull on the ligaments (Cooper’s ligaments) that connect the breast skin to the underlying tissue.

What to do: Any new dimpling or puckering should be evaluated.

3. Nipple Changes

What to look for:

• A nipple that suddenly turns inward (inversion)

• Nipple flattening

• A change in nipple position

• A rash, crusting, or scaling on the nipple or areola

What to do: Nipple changes can be caused by benign conditions, but they should always be evaluated.

4. Nipple Discharge

What to look for: Discharge that happens without squeezing (spontaneous). Discharge that is clear, bloody, or yellow. Discharge that comes from only one breast.

What to do: A small amount of milky discharge from both breasts when squeezed is usually normal. Spontaneous, bloody, or one-sided discharge should be evaluated.

5. Swelling or Thickening

What it looks like: A portion of the breast that feels thicker or heavier than the surrounding tissue. Swelling that doesn’t go away with your cycle.

What to do: Any area of persistent thickening or swelling should be evaluated.

6. Redness or Warmth

What it looks like: Red, warm, or inflamed skin on the breast. May be accompanied by swelling or dimpling.

Why it happens: Inflammatory breast cancer (a rare but aggressive form) can cause redness and warmth without a distinct lump.

What to do: Any persistent redness, warmth, or inflammation should be evaluated promptly.

7. Change in Breast Size or Shape

What it looks like: One breast becomes noticeably larger or lower than the other. A change in the overall contour of the breast.

What to do: Asymmetry is normal, but new or worsening asymmetry should be evaluated.

8. Pain (Mammary Pain)

What it feels like: Persistent pain in one specific area of the breast. Pain that doesn’t fluctuate with your cycle.

What to do: Most breast pain is not cancer. But persistent, localized pain should be evaluated.

What About the “Invisible” Signs? (Things You Can’t See or Feel)

Some signs of breast cancer are not visible or palpable. They’re detected through screening.

• Microcalcifications: Tiny calcium deposits seen on a mammogram. Most are benign, but some patterns can indicate early cancer.

• Architectural distortion: Changes in the normal structure of the breast tissue seen on imaging.

This is why regular mammograms are so important—they can catch changes before you can feel or see them.

The Importance of Regular Screening

Let me give you the current guidelines.

High-risk individuals (strong family history, genetic mutations, previous chest radiation) may need earlier or more frequent screening. Talk to your doctor.

When to See a Doctor (The “Don’t Wait” List)

Let me make this simple.

See a doctor if you notice:

• A new lump or mass (especially if it doesn’t go away)

• Skin dimpling or puckering (like an orange peel)

• Nipple changes (inversion, flattening, crusting, scaling)

• Spontaneous nipple discharge (especially if clear, bloody, or one-sided)

• Persistent swelling, thickening, or warmth

• A change in breast size or shape

• Persistent pain in one area

You do NOT need to see a doctor for:

• Cyclical pain that comes and goes with your period

• Mild, occasional lumpiness that changes with your cycle

• Small, tender lumps that appear before your period and disappear afterward

When in doubt, ask. There’s no shame in being cautious. Doctors have seen everything. They will not think you’re silly for getting a lump checked.

How to Do a Breast Self-Exam (The Right Way)

Breast self-exams are no longer formally recommended as a screening tool (because they haven’t been shown to reduce mortality). However, self-awareness—knowing what is normal for your breasts—is still valuable.

The method (if you choose to do self-exams):

Step 1: Stand in front of a mirror with your shoulders straight and your hands on your hips. Look for dimpling, puckering, changes in size or shape, or nipple changes.

Step 2: Raise your arms above your head. Look for the same changes.

Step 3: Lie down. Use the pads of your three middle fingers to feel your breast tissue. Use a circular motion, covering the entire breast from collarbone to bra line, and from armpit to breastbone.

Step 4: Feel for lumps, thickening, or hardened knots.

Step 5: Repeat on the other side.

How often: Once a month, a few days after your period ends (when breasts are least tender).

Important: Self-exams are not a substitute for mammograms or clinical exams. They are an additional tool for self-awareness.

What About Dense Breasts? (A Special Consideration)

Dense breast tissue is normal. It’s not a disease. But it does make mammograms harder to read.

What it means: Dense breasts have more glandular and connective tissue than fat. On a mammogram, dense tissue appears white, and tumors also appear white—so tumors can be “hidden” in the density.

What to do: If you have dense breasts, your radiologist may recommend additional screening (ultrasound, MRI). Talk to your doctor.

The good news: You can’t change your breast density. It’s genetic. But you can be aware of it and advocate for appropriate screening.

The Emotional Side: Fear, Anxiety, and Self-Advocacy
