Hello! It is recommended to undergo an ultrasound at a general surgery or breast surgery department.
Your description is most likely indicative of a fibroadenoma or a fibrocystic condition.
Given your age, I suggest that the hospital retains the ultrasound and mammogram for future comparison.
After all, breast cancer is becoming more prevalent among younger individuals, so close monitoring is the safest approach.
Changhua Hospital cares about you!

More Info

Breast lumps can be a source of concern for many individuals, especially when they notice changes in their breast tissue. Understanding the causes, symptoms, and when to seek medical attention is crucial for maintaining breast health.

Causes of Breast Lumps
1. Fibrocystic Changes: This is one of the most common causes of breast lumps, particularly in women of reproductive age. It is characterized by the presence of cysts and fibrous tissue in the breast, which can lead to lumps that may change in size and tenderness in relation to the menstrual cycle.

2. Fibroadenomas: These are benign tumors made up of glandular and connective tissue. They are usually painless, movable, and can vary in size. Fibroadenomas are most common in younger women and may also fluctuate in size with hormonal changes.

3. Cysts: Fluid-filled sacs that can develop in the breast tissue. They can be tender or painless and may vary in size. Cysts are often influenced by hormonal changes, particularly during the menstrual cycle.

4. Infections or Inflammatory Conditions: Conditions such as mastitis or abscesses can cause lumps in the breast, often accompanied by pain, redness, and swelling.

5. Breast Cancer: While many breast lumps are benign, it is essential to be aware that breast cancer can also present as a lump. Cancerous lumps are typically hard, irregular in shape, and may be fixed to the surrounding tissue.

Symptoms to Monitor
- Size and Shape Changes: If the lump changes in size, especially if it enlarges after menstruation, it may be related to hormonal fluctuations. However, any persistent change should be evaluated by a healthcare provider.

- Pain: While many benign lumps are painless, any new pain associated with a lump should be assessed, especially if it is persistent or worsening.

- Skin Changes: Look for any changes in the skin over the lump, such as dimpling, puckering, or redness, which may indicate a more serious condition.

- Nipple Discharge: Any unusual discharge from the nipple, especially if it is bloody or occurs without squeezing, should be evaluated.

When to Worry
You should seek medical attention if you notice any of the following:
- A lump that persists through your menstrual cycle or does not change in size.

- A lump that feels hard, irregular, or fixed to the surrounding tissue.

- Any new or unusual changes in the breast, such as skin changes or discharge.

- A family history of breast cancer or other risk factors that may increase your likelihood of developing breast cancer.

Recommended Actions
1. Self-Examination: Regular breast self-exams can help you become familiar with your breast tissue and identify any changes early.

2. Professional Evaluation: If you find a lump, especially one that is new or has changed, it is essential to consult a healthcare provider. They may recommend imaging tests such as a mammogram or ultrasound to further evaluate the lump.

3. Follow-Up: If a lump is found to be benign, regular follow-up may be necessary to monitor any changes. If there are concerns about cancer, a biopsy may be performed to determine the nature of the lump.

In conclusion, while many breast lumps are benign and related to hormonal changes, it is essential to monitor any changes and consult a healthcare provider for a thorough evaluation. Early detection and intervention are key to managing breast health effectively.
