It’s good to be aware of real warning signs—early detection of breast cancer can make a big difference. Here are 10 important symptoms you should never ignore:
1. A new lump in the breast or underarm
Often painless and hard, but can vary.
One of the most common early signs.
—
2. Swelling of part or all of the breast
Even if no distinct lump is felt.
—
3. Skin irritation or dimpling
Skin may look like an orange peel (called peau d’orange).
—
4. Breast or nipple pain
Not the most common sign, but persistent, localized pain matters.
—
5. Nipple retraction (turning inward)
Especially if it’s a new change.
—
6. Redness, scaliness, or thickened nipple or breast skin
Can resemble a rash or infection but doesn’t go away.
—
7. Nipple discharge (other than breast milk)
Especially bloody or clear discharge from one breast.
—
8. Change in size or shape of the breast
Sudden or unexplained asymmetry.
—
9. Swollen lymph nodes
Found under the arm or near the collarbone.
—
10. Persistent warmth or redness in the breast
Could indicate infection—but sometimes linked to inflammatory breast cancer, a rarer but aggressive form.
—
⚠️ Important to remember
Many of these signs can be caused by non-cancerous conditions.
But if a symptom is new, unusual, or doesn’t go away, it’s important to get it checked.
