Differential Diagnosis for Breast Pain with Bulge Feeling

Single Most Likely Diagnosis

• Fibrocystic Breast Changes: This condition is very common and can cause breast pain, lumps, and a bulge feeling due to the formation of cysts and fibrous tissue in the breast.

Other Likely Diagnoses

• Breast Cyst: A fluid-filled sac within the breast that can cause pain and a bulge feeling, especially if it becomes large or ruptures.
• Fibroadenoma: A benign tumor of the breast that can cause a bulge and may be painful, especially if it grows rapidly.
• Hormonal Fluctuations: Changes in hormone levels during the menstrual cycle or with hormone replacement therapy can lead to breast tenderness and a feeling of fullness or bulge.

Do Not Miss Diagnoses

• Breast Cancer: Although less common, breast cancer can present with pain and a bulge, especially if the tumor is large or located near the surface of the breast. It's crucial to rule out cancer due to its serious implications.
• Breast Abscess: An infection of the breast tissue that can cause pain, swelling, and a bulge, which requires prompt medical attention to prevent serious complications.
• Phyllodes Tumor: A rare type of breast tumor that can be benign, borderline, or malignant and may present with a rapidly growing bulge and pain.

Rare Diagnoses

• Galactocele: A milk-filled cyst that can occur in lactating women, causing a bulge and potentially pain if it becomes infected or large.
• Hamartoma: A benign growth in the breast composed of a mixture of tissues, which can cause a bulge and may be painful.
• Lipoma: A benign tumor made of fat tissue that can occur in the breast, causing a bulge, and may be painful if it presses on surrounding tissues.
