It’s Breast Cancer Awareness Month, which means now is a good time to learn the symptoms of breast cancer (if you don’t know them already). Early detection is crucial, and while some people may not show signs, it’s important to recognize common symptoms when they occur.

Here are a few warning signs to be aware of:

• A lump in the breast or underarm
• Unexplained swelling or thickening in part of the breast
• Changes in breast size, shape, or appearance
• Skin irritation or dimpling
