DDX for breast swelling of 2 year duration

There are several potential differential diagnoses (DDX) for breast swelling of 2 year duration, including:

1. Fibrocystic breast changes: This is a very common condition that causes lumps, swelling, and tenderness in the breasts. It is due to hormonal changes and often occurs in premenopausal women.

2. Fibroadenoma: This is a benign breast tumor that is usually painless and feels like a smooth, firm lump. It is more common in young women.

3. Breast infection (mastitis): This can cause breast swelling, redness, warmth, and pain. It is more common in breastfeeding women but can also occur in women who are not breastfeeding.

4. Lipoma: This is a benign fatty tumor that can occur in the breast and cause swelling. It is usually painless and feels soft.

5. Breast cancer: While breast cancer is less likely to be the cause of breast swelling in a young woman, it is still important to consider.

6. Breast abscess: This is a more serious type of breast infection that can cause a painful, swollen lump in the breast. It is often associated with fever and requires medical attention.

7. Hormonal imbalances: Certain hormonal conditions, such as polycystic ovary syndrome (PCOS), can cause breast swelling.

It is important to see a healthcare professional for a thorough evaluation and appropriate testing to determine the underlying cause of the breast swelling.
