Signs and Symptoms
Early breast cancer usually doesn't cause pain. In fact, when breast cancer first develops, there may be no symptoms at all. But as the cancer grows, it may cause changes that you should watch for:
- A lump or thickening in or near the breast or in the underarm area
- A change in the size or shape of the breast
- Nipple discharge or tenderness, or the nipple pulled back (inverted) into the breast
- Ridges or pitting of the breast, making the skin look like the skin of an orange
- A change in the look or feel of the skin of the breast, areola or nipple such as warmth, swelling, redness or scaliness
