Quick Answer

Benign (non-cancerous) causes are most common:

Less common but important causes include:

Even though most breast lumps are not cancer, certain features mean it’s important to have it evaluated.

Contact your doctor: A new breast lump should be discussed with your doctor, even though most are not cancer.

Clinical exam: Your doctor may examine the area and ask about timing, pain, changes, family history, and other symptoms.

Imaging if needed: Your doctor may order a diagnostic mammogram, breast ultrasound, or both, depending on your age and symptoms.

Biopsy only if needed: If imaging shows something unclear or suspicious, a biopsy may be recommended to get a definite answer.

These are the most common questions patients have when they find a breast lump.

Most breast lumps are not cancer. Only a small percentage are.

Common causes include cysts, fibroadenomas, and hormonal changes.

You cannot tell by feel alone, so evaluation is important.

Skin changes or nipple changes are also important signs.

These tests are highly accurate in determining the cause.
