Menstrual Irregularities and Breast Lumps: What You Need to Know

Regarding the issues of inducing menstruation and breast lumps?

I haven't had my period for a long time, approximately six months.
My menstrual cycle is usually every two to three months, and it's been very irregular.
I went to a clinic for a menstrual induction injection and took medication.
I received the injection on March 1st, but I still haven't gotten my period.
The clinic is quite small, so they didn't perform an ultrasound.
The next day, while taking a shower, I discovered a round, hard lump near the sternum, just below my right breast.
It's about the width of a finger, doesn't hurt, and there is no discharge.
I'm not sure if it moves; I can't really tell.
I wonder if this could be related to the medication I took, or should I go to a hospital for more detailed examinations? I'm feeling quite anxious about it.
Could you please help me with this? Thank you.

1.
If your menstrual period has not arrived, you are welcome to visit our obstetrics and gynecology department for an examination, where we will perform an ultrasound.

2.
The presence of a lump in the breast is generally not significantly related to medication or injections.
Please promptly visit a breast surgery specialist for an evaluation.
Thank you! Hsinchu City Hospital, Department of Obstetrics and Gynecology.

Menstrual irregularities and breast lumps can be concerning, and it's important to understand both conditions to address your worries effectively.
Firstly, menstrual irregularities can arise from various factors, including hormonal imbalances, stress, significant weight changes, or underlying medical conditions such as polycystic ovary syndrome (PCOS) or thyroid disorders. In your case, having irregular periods for several months and then receiving hormonal treatment (like the injection you mentioned) may have contributed to the changes in your menstrual cycle. It's not uncommon for hormonal treatments to take some time to regulate your cycle, and sometimes they can cause temporary changes in your body that might lead to further irregularities.

The absence of menstruation for an extended period, especially after a history of irregular cycles, can be frustrating and concerning. If you have not had a period since receiving the injection on March 1, it would be wise to follow up with a healthcare provider. They may recommend further evaluation, including blood tests to check hormone levels, and possibly imaging studies like an ultrasound to assess your reproductive organs.

Now, regarding the breast lump you discovered, it’s understandable to feel anxious. Breast lumps can arise from various causes, including benign conditions such as cysts, fibroadenomas, or fibrocystic changes, as well as more serious conditions like breast cancer. The fact that the lump is not painful and does not have any discharge is somewhat reassuring, but it does not eliminate the need for further evaluation.

Hormonal changes, especially those related to menstrual irregularities, can sometimes lead to breast tissue changes, which might explain the lump. However, it is crucial to have any new breast lump evaluated by a healthcare professional. They may perform a clinical breast exam and recommend imaging studies, such as a mammogram or ultrasound, to better understand the nature of the lump. In some cases, a biopsy may be necessary to determine if the lump is benign or malignant.

In summary, both your menstrual irregularities and the breast lump warrant further investigation. It is essential to consult with a healthcare provider who can perform a thorough evaluation and guide you through the necessary steps. Early detection and diagnosis are key in managing any potential health issues, so do not hesitate to seek medical attention. Your health and peace of mind are paramount, and addressing these concerns with a professional will help you feel more secure.
