Dear Miss Ruby, about ten days after your menstrual period, you noticed a small hard lump the size of a grain of rice beneath your breast.
Please do not worry for now; observe it for a few more days.
If it persists, you can visit a general surgeon or a breast specialist for an examination.
Generally speaking, based on your description, it is likely to be a benign subcutaneous tumor.
Wishing you good health.

When it comes to discovering small hard lumps under the breast, particularly after your menstrual period, it’s understandable to feel concerned. The presence of a lump can evoke anxiety, especially regarding the potential for tumors or other serious conditions. However, it’s important to approach this situation with a balanced perspective, considering both the common benign causes and the need for medical evaluation.

Firstly, it’s essential to recognize that breast tissue is subject to various physiological changes due to hormonal fluctuations, especially during the menstrual cycle. Many women experience changes in breast tissue that can lead to the formation of lumps or nodules. These lumps can often be attributed to benign conditions such as fibrocystic breast changes, which are characterized by the presence of cysts and fibrous tissue. These changes can cause tenderness and the formation of small lumps that may feel movable and can vary in size.

In your case, the lump you described as being the size of a grain of rice could potentially be a benign cyst or a fibroadenoma, both of which are common in women of reproductive age. Cysts are fluid-filled sacs that can develop in the breast tissue, while fibroadenomas are solid, non-cancerous tumors made up of glandular and connective tissue. Both conditions are typically not associated with cancer and often do not require treatment unless they cause discomfort or concern.

However, it is crucial to monitor the lump for any changes. If the lump persists, increases in size, or if you experience additional symptoms such as pain, changes in the skin over the lump, or unusual discharge from the nipple, it is advisable to seek medical attention. A healthcare provider, particularly a breast specialist, can perform a clinical examination and may recommend imaging studies such as a mammogram or ultrasound to evaluate the lump further.

In terms of cancer risk, while most breast lumps are benign, it’s important to be aware of your personal and family medical history. Factors such as a family history of breast cancer, genetic predispositions (like BRCA mutations), and other risk factors can influence your overall risk. Regular breast self-exams and routine screenings, such as mammograms, are essential for early detection of any potential issues.

In summary, while the lump you discovered may likely be benign, it is always best to err on the side of caution. If you have any doubts or if the lump does not resolve, please consult with a healthcare professional. They can provide a thorough evaluation and peace of mind, ensuring that any necessary follow-up or treatment is appropriately managed. Remember, being proactive about your breast health is key to maintaining overall well-being.
