Breast Fold Lines: Should You Worry About Breast Cancer? - Breast and Thyroid

Folds beneath the areola?


Hello Doctor: In the past two days, I have noticed a fold line under each areola.
The fold on the left side is more pronounced due to the asymmetry in breast size.
The folds are visible when standing or sitting, but less noticeable when lying down.
I have previously undergone breast ultrasound and mammography, and the doctor mentioned the presence of cysts and calcifications, so I have been monitored annually (with breast ultrasound and mammography) for many years.
The most recent examination was in April of this year, and the doctor advised that the calcifications should continue to be monitored.
I would like to ask, could this be breast cancer? Thank you for your response.

Based on your description of the breast cancer risk, it should not be a concern for breast cancer.
Some of these issues may even be related to lymphatic circulation swelling.

More Info


Breast fold lines, or the creases that can appear beneath the areola, are often a normal anatomical feature and can be influenced by various factors, including breast size, skin elasticity, and body position. In your case, the observation of these lines, particularly if they are more pronounced when standing or sitting, is likely related to the natural movement and positioning of breast tissue rather than an indication of breast cancer.

Breast cancer typically presents with more concerning symptoms, such as a palpable lump, changes in breast shape or size, skin changes (like dimpling or puckering), or unusual discharge from the nipple. The presence of fold lines alone, especially if they have not changed significantly over time, is not a common indicator of breast cancer.
You mentioned that you have a history of breast ultrasounds and mammograms, which is excellent for monitoring breast health. The fact that your doctor has noted the presence of cysts and calcifications but has advised continued monitoring suggests that they are not currently considered worrisome. Calcifications can be benign or indicative of early changes in breast tissue, but they are often not a direct sign of cancer, especially if they are stable over time.

It is important to maintain regular follow-ups with your healthcare provider, as they can assess any changes in your breast tissue and determine if further investigation is necessary. If you notice any new symptoms, such as a change in the appearance of the fold lines, new lumps, or any other unusual changes, you should report these to your doctor promptly.

In summary, while it is natural to be concerned about any changes in your body, the presence of fold lines beneath the areola is generally not a cause for alarm regarding breast cancer. Continue your routine screenings and discussions with your healthcare provider, and trust their guidance based on your individual health history and risk factors. If you have further questions or concerns, do not hesitate to reach out to your medical team for personalized advice. Your proactive approach to monitoring your breast health is commendable and essential in ensuring early detection of any potential issues.
