Q: Breast Lumps: Causes and When to Seek Ultrasound

Dear AKI： It may be a skin cyst, which can sometimes disappear on its own. <br>However, if it enlarges or presents symptoms, surgical removal may be necessary.

Breast lump

Hello, doctor.
I would like to ask about a round hard lump I found today on the inner side of my lower left chest, near the xiphoid process.
It is less than 1 centimeter, painful to touch, and does not move.
I did not notice it a few days ago.
What could be the cause of this? Should I get an ultrasound for examination?

Breast lumps can be concerning, and it's essential to understand their potential causes and when to seek further evaluation, such as an ultrasound. Based on your description of a round, hard lump located near the sternum (the breastbone) that is less than 1 cm in size, tender to touch, and not movable, there are several possibilities to consider.

1. Fibroadenoma: This is a common benign tumor found in young women. It typically feels like a smooth, firm lump and can be movable. However, if it is tender and hard, it may not fit this description perfectly.

2. Cysts: Breast cysts are fluid-filled sacs that can develop in the breast tissue. They can sometimes be tender, especially if they are inflamed or if there is a change in hormonal levels. Cysts can vary in size and may feel firm or soft.

3. Fibrocystic Changes: Many women experience fibrocystic breast changes, which can lead to lumps that may be painful, especially before menstruation. These changes are usually related to hormonal fluctuations and can cause lumps that may feel tender and can vary in size.

4. Infection or Inflammation: Conditions such as mastitis (an infection of breast tissue) can cause painful lumps. This is more common in breastfeeding women but can occur in others as well. If there is redness, warmth, or discharge, this could be a sign of infection.

5. Other Causes: Less commonly, breast lumps can be caused by more serious conditions, including breast cancer. While the characteristics you describe (small size, tenderness) are more typical of benign conditions, any new lump should be evaluated.

Given that the lump is new, tender, and you have not noticed it before, it is advisable to seek further evaluation. An ultrasound is a non-invasive imaging technique that can help differentiate between solid masses and cysts and provide more information about the lump's characteristics. It is particularly useful in assessing breast lumps in women of all ages and can guide further management.

When to Seek Ultrasound:
- If the lump is new and persistent.

- If there are changes in the lump's size or characteristics.

- If you experience additional symptoms such as changes in the skin over the breast, discharge from the nipple, or significant pain.

- If you have a family history of breast cancer or other risk factors.

Conclusion:
In summary, while many breast lumps are benign, it is crucial to have any new or concerning lumps evaluated by a healthcare professional. An ultrasound can provide valuable information and help determine the appropriate next steps. It is always better to err on the side of caution when it comes to breast health. If you have any further concerns or if the lump changes, please consult your healthcare provider as soon as possible.
