Can Breast Surgery Affect Your Period?

There are a number of reasons why this happens, but the most common one has to do with the way the body responds to surgery.

Are you considering breast surgery, but worried about the potential impact on your monthly cycle? It’s a common concern among women who are looking to enhance their breasts, reduce their size or get reconstruction after mastectomy. The good news is that breast surgery typically does not affect menstruation in any significant way. However, there are some rare cases where changes can occur. In this blog post, we’ll explore the relationship between breast surgery and periods so you can make an informed decision about your procedure.


It’s a question that many women have but are afraid to ask: can breast surgery affect your period? The answer is yes, Breast surgery – including reduction mammoplasty (breast reduction), mastectomy (breast removal) and even biopsies – can disrupt the normal functioning of the menstrual cycle.

There are a number of reasons why this happens, but the most common one has to do with the way the body responds to surgery. When any kind of surgery is performed, the body releases stress hormones like cortisol and adrenaline. These hormones can interfere with the production of other hormones like progesterone and estrogen, which are responsible for regulating the menstrual cycle. Additionally, any type of trauma to the breasts – including surgery – can cause inflammation and scarring, which can also disrupt hormone production.

The good news is that in most cases, these effects are only temporary and your period should eventually return to normal within a few months. However, there is a small percentage of women who may experience more long-lasting changes to their menstrual cycle after breast surgery. If you notice any changes in your period that persist for more than a few months, it’s important to speak with your doctor so they can determine if there is another underlying cause.

What Types of Breast Surgery Can Affect Your Period?

It’s not uncommon for women to wonder how different types of breast surgery will affect their period. Here’s a brief overview of the most common procedures and their potential impact on your menstrual cycle:

Breast augmentation: Breast augmentation surgery involves increasing the size and/or changing the shape of the breasts with implants. This type of surgery generally doesn’t have any effect on menstruation.

Breast lift: A breast lift, also called a mastopexy, is a surgical procedure that lifts and reshapes sagging breasts. This type of surgery usually doesn’t have any effect on menstruation either.

Breast reduction: Breast reduction surgery involves removal of excess breast tissue to reduce breast size. This type of surgery can sometimes cause irregular periods or even menopause in some women.

Reconstruction after mastectomy: Reconstruction after mastectomy is a complex series of surgeries that rebuild the shape of the breast after cancer treatment. This type of surgery can sometimes cause irregular periods or even menopause in some women.

The Impact of Hormonal Birth Control on Menstrual Cycles After Breast Surgery

The hormonal effects of birth control can impact the menstrual cycles of women who have undergone breast surgery. While some types of birth control may help to regulate periods and reduce period-related symptoms, others can cause changes in bleeding patterns or missed periods. In some cases, the hormones in birth control can also interfere with the body’s natural hormone levels, which can impact fertility. If you are considering breast surgery, it is important to talk to your doctor about how it may affect your menstrual cycle and whether or not you should use birth control to prevent any unwanted side effects.

How Diet and Exercise Affects Post-Surgery Menstruation

After undergoing surgery, it is normal for patients to experience changes in their menstrual cycle. However, these changes can vary depending on the type of surgery that was performed. For example, a mastectomy (removal of the breast) can cause amenorrhea (absence of menstrual periods), while a lumpectomy (removal of only a portion of the breast) typically does not have this effect. In addition, diet and exercise can also impact post-surgery menstruation.

Patients who are trying to lose weight or improve their fitness levels may find that their menstrual cycles become irregular or even stop altogether. This is because losing weight or exercising excessively can lead to a decrease in body fat, which can in turn affect hormone levels and disrupt the normal menstrual cycle. On the other hand, gaining weight or becoming more sedentary can also impact hormone levels and result in irregular periods or amenorrhea.

In general, it is best to maintain a healthy weight and moderate exercise level during and after breast surgery to minimize the risk of developing irregular periods. If you are concerned about your menstrual cycle after surgery, be sure to discuss this with your doctor so that they can provide you with individualized guidance.

Should You See a Doctor if You Notice Changes in Your Period After Breast Surgery?

If you have any concerns about changes in your period after breast surgery, it’s best to see a doctor. While some changes are normal and to be expected, others could be indicative of a more serious problem.

Most women will experience some changes in their period after breast surgery. These can include light spotting or bleeding, irregularity, or a complete stop in menstruation. The type and severity of changes will depend on the type of surgery you had and how your body responds to it.

In most cases, these changes are nothing to worry about and will eventually return to normal on their own. However, if you experience any prolonged or severe changes, or if you have any other issues such as pain or abnormal discharge, it’s important to see a doctor so that they can rule out any underlying problems.


Breast surgery can have a variety of effects on your period, ranging from mild to severe. Before deciding to undergo any type of breast procedure, it is important to understand the risks and benefits involved. Talk with your doctor about all possible outcomes so that you are well-informed before going into any surgical setting. Ultimately, it’s up to you what choice is best for your body and its health needs.
