Persistent Breast Lesion: Symptoms and Concerns - Obstetrics and Gynecology

When it comes to persistent breast lesions, it’s essential to approach the situation with a clear understanding of the symptoms and potential underlying conditions. Based on your description, it sounds like you have a lesion located beneath the areola of your right breast that has been present for about a year. The fact that it produces pus upon squeezing suggests that it may be an infected cyst or an abscess rather than a malignant condition like breast cancer.

Breast lesions can arise from various causes, including benign conditions such as cysts, fibroadenomas, or infections. In your case, the presence of pus indicates that there may be an infection involved, which could be due to a blocked milk duct or a skin infection. The fact that it is not painful and does not have an unpleasant odor is somewhat reassuring, as these characteristics are often associated with more serious conditions.

One possibility you mentioned is a "乳線瘤" (lactiferous duct cyst), which can occur when a milk duct becomes blocked, leading to fluid accumulation and potential infection. These cysts can sometimes resolve on their own, but if they become infected, they may require medical intervention, such as drainage or antibiotics.

It’s important to note that while breast cancer can present as a lump or lesion, it typically has other associated symptoms, such as changes in the skin, discharge that may be bloody or have an unusual odor, or changes in the shape or size of the breast. Your lesion's characteristics—being present for a year, producing pus, and not being painful—are more suggestive of a benign process.

Given the duration of your symptoms and the fact that the lesion has not resolved, it is highly advisable to seek medical evaluation. A healthcare provider can perform a physical examination and may recommend imaging studies, such as an ultrasound or mammogram, to further assess the lesion. In some cases, a biopsy may be necessary to definitively determine the nature of the lesion.

In the meantime, avoid squeezing or manipulating the lesion, as this can exacerbate any underlying infection and lead to further complications. Keeping the area clean and dry is essential, and if you notice any changes, such as increased redness, swelling, or fever, you should seek medical attention promptly.

In summary, while your concerns about breast cancer are understandable, the characteristics of your lesion suggest a more benign condition, possibly an infected cyst. However, only a healthcare professional can provide a definitive diagnosis and appropriate treatment plan. It’s crucial to follow up with a medical provider to ensure that you receive the care you need and to alleviate your concerns.
