Explanation

When you find a lump in your breast, it can be worrisome. Most breast lumps are not cancerous, but it's important to know when to see a doctor.

When to be Concerned:

Hard or Firm Lumps: If the lump feels very hard or firm, it might need more attention.
Growing Lumps: If the lump is getting bigger over time, it's a good idea to get it checked.
Skin Changes: Look for changes in the skin over the lump, like dimpling or redness.
Pain or Tenderness: Some lumps can be painful. Pain alone doesn't mean it's serious, but it's worth checking out.

See a Doctor: If you notice any of these signs, make an appointment with your doctor. They might do tests to find out more about the lump.
