Lump in the breast?


Hello doctor, about six months ago, I noticed lumps and a cord-like structure in my breast while showering, with the left breast being more pronounced.
They have not disappeared since then.
When I wear a bra, the underwire causes some pain, which is only present in the left breast.
About ten days before my menstrual period, I feel that the area slightly enlarges, but it does not go away after my period ends; the lumps remain.
I would like to know if this is normal fibrocystic breast changes or a tumor.
My breasts are quite small and feel firmer compared to other women’s softer breasts, making self-examination difficult.
I'm unsure if what I'm feeling is normal breast tissue or problematic lumps.

Breast lumps can be a source of concern for many individuals, especially when they are first discovered. Understanding whether these lumps are normal breast tissue or a cause for concern is crucial for maintaining breast health. Based on your description, it seems that you have been experiencing some discomfort and have noticed lumps or irregularities in your left breast. Let's delve into the possible causes and what steps you should take.

Firstly, it is important to recognize that breast tissue can undergo various changes throughout a woman's life, particularly due to hormonal fluctuations associated with the menstrual cycle. The breast is composed of glandular tissue, connective tissue, and fat, and it is normal for the density and texture of breast tissue to vary. Many women experience breast tenderness, swelling, or lumpiness in the days leading up to their menstrual period due to hormonal changes, particularly an increase in estrogen levels during the follicular phase of the cycle.

In your case, you mentioned that the lumps are more pronounced in the left breast and that you experience some pain, especially when wearing a bra with underwire. This discomfort could be attributed to a condition known as fibrocystic breast changes, which is characterized by lumpy, painful breasts that can fluctuate in size and tenderness with the menstrual cycle. These changes are generally benign and are caused by hormonal influences, but they can be uncomfortable.

However, it is essential to differentiate between benign conditions and potential malignancies. The fact that you have noticed these lumps persisting for six months without any change in size or resolution is a point of concern. While many breast lumps are benign, such as cysts or fibrocystic changes, any new or persistent lump should be evaluated by a healthcare professional.
Given your description of the lumps being hard and the difficulty in self-examination, it is advisable to schedule an appointment with a healthcare provider, preferably a breast specialist or a gynecologist. They may recommend imaging studies such as a mammogram or breast ultrasound to assess the nature of the lumps. These imaging techniques can help determine whether the lumps are solid masses, which may require further evaluation, or fluid-filled cysts, which are often benign.

In addition to imaging, a clinical breast examination by a healthcare provider can provide valuable insights. They can assess the lumps' characteristics, such as their size, shape, and mobility, and determine if any further testing, such as a biopsy, is necessary.

It is also worth noting that breast health is influenced by various factors, including genetics, lifestyle, and hormonal balance. Maintaining a healthy lifestyle, including regular exercise, a balanced diet, and avoiding smoking and excessive alcohol consumption, can contribute to overall breast health.

In summary, while hormonal changes can lead to benign breast lumps, any persistent or concerning changes in breast tissue warrant further investigation. It is crucial to consult with a healthcare professional who can provide a thorough evaluation and guide you through the appropriate diagnostic steps. Early detection and intervention are key to managing breast health effectively, so do not hesitate to seek medical advice.
