Fibrocystic breast disease is also known as fibrocystic changes. It is a common benign condition in women which results in lumps and cysts in the breasts.

About 50% of women experience fibrocystic changes in their breasts, generally between the ages of 20 and 50.

The causes of fibrocystic breast disease are interrelated and complex, involving several factors. 

These causes can vary from person to person, as some women might be more vulnerable to one element than others.

Hence, understanding fibrocystic breast disease causes can give valuable insights into its management and prevention.

Causes of fibrocystic breast disease

Though it is common in women, experts don’t know the exact cause of the change in breast tissue. 

However, the leading cause is believed to be the fluctuating levels of hormones like Estrogen. 

Among these, there are other causes as well. Let’s see the reasons:

Hormone fluctuations

Fibrocystic breast disease development is significantly influenced by hormonal imbalances, with the ovaries producing estrogen and progesterone.

Any changes in the levels of these hormones can lead to the formation of breast lumps and cysts. 

These changes are most likely to occur in the luteal phase, i.e., before your menstruation cycle, and they can ease up when you begin to menstruate.

These hormonal changes can result from an overgrowth of breast tissue and developing breast cysts or fibrous areas. 

There can be swelling of your breast lobules, and you may feel some pain and tenderness.

Research done on 300 women revealed that benign breast disease is strongly linked with women who receive estrogen and anti-estrogen treatments. 

In a study conducted for breast cancer on premenopausal and postmenopausal, it was found that women who have entered menopause have less chance of contracting fibrocystic breast disease. 

But if postmenopausal women have received estrogen and progestin therapy for over eight years, their chances of having benign breast lesions increase by 1.7 times. 

According to the Women’s Health Initiative study on breast cancer, using both estrogen and progestin together increases the risk of benign breast disease like fibrocystic breast disease by 74%. 

On the contrary, using only anti-estrogens reduces the occurrence of benign breast changes by 28%.

Another factor of hormonal imbalance is Polycystic Ovary Syndrome (PCOS), a common condition among menstruating women. 

In PCOS, women have irregular ovulation and increase in male hormone levels, leading to irregular periods. 

Warning:
Polycystic Ovary Syndrome (PCOS) is a complex hormonal disorder associated with various long-term complications, such as infertility, type 2 diabetes, cardiovascular disease, and endometrial cancer. So, it is important to seek medical attention.

The experts at Coimbra University Hospital concluded that fluctuations in Estrogen and Progesterone combined with irregular ovulation and periods are connected to benign fibrocystic changes in the breast. 

Age and reproductive factors

Women of reproductive age, typically between 20 and 50, are more prone to fibrocystic breast disease. 

But the risk of forming cysts and an increase in fibrous tissue increases if a woman has not given birth or has a late first pregnancy. 

As per a study conducted on 283 women, premenopausal women with fewer children are more likely to get fibrocystic breast disease. 

Interestingly, women who had their first pregnancy at a late age are still at higher risk for benign breast disease, regardless of the number of children they had after their first child. 

Similarly, women experiencing menopause at a later age have an increased likelihood of getting benign changes in their breasts. 

The condition tends to improve after menopause when hormonal fluctuations decrease unless you are having hormonal therapy. 

Lifestyle factors

Several lifestyle factors can also influence fibrocystic breast disease.

It is important to note that lifestyle and socioeconomic factors are related. 

Both premenopausal and postmenopausal women of higher socioeconomic status have higher chances of getting fibrocystic breast disease. 

Women of high socioeconomic will be able to consume caffeine and alcohol more, and they are connected to fibrocystic changes and breast pain. 

A study was conducted on 634 women where it was found that women who consumed 31-250 mg of caffeine daily had 1.5 times higher risk.

In comparison, those who consumed over 500 mg daily had a 2.3 times higher risk.

The link between caffeine consumption and fibrocystic breast disease was strong in women with pre-existing conditions like abnormal growth of cells in the breast’s lobules and Hyperplasia— an increase in the number of cells. 

Another study showed that smoking excessively may contribute to hormonal imbalances and worsen the condition.

Additionally, intake of alcohol can increase the risk of breast changes, particularly in women ages 18 to 22.

An additional research showed that body mass index is also a risk factor in contracting changes in the breast. 

Women with lower-body mass indexes are at more risk than those with higher body mass indexes. 

Genetic and Pre-existing conditions

According to research, genetics may increase susceptibility to fibrocystic breast disease. 

If you have a family history of the condition, you may be more likely to develop it.

A pre-menopausal woman with a family history of breast cancer (mother or sister) is more prone to get fibrocystic breast disease.

In comparison, if postmenopausal women have a history of benign breast disease, she has an increased chance of having fibrocystic breast disease.

How does fibrocystic breast disease affect the body?

Fibrocystic breast disease can cause many symptoms and affect the body in the following way:

Breast pain

Breast pain, tenderness, or soreness is common in women with fibrocystic breast disease. 

The intensity of pain or tenderness varies and can get worse before menstruation.

Breast lumps

The breasts can develop free-moving clots, often near the armpit. 

These lumps can be either fibrous tissue or cysts filled with fluid, which is asymptomatic and causes no pain.

Fact:
Many women’s breast cysts don’t have symptoms. Only about 7 % of women have a breast cyst that you can feel with the hand.

Breast swelling

The breasts may feel fuller or swollen due to cysts or more fibrous tissue.

Breast changes

While examining your breasts, you can feel the changes in breast texture, such as a lumpy or rope-like feeling.

The texture will get better once you start your period.

Consult a doctor

As fibrocystic breast disease is common, it is generally not regarded as a disease but changes in the breasts.

Commonly, fibrocystic changes aren’t considered harmful. 

Certain conditions, such as unusual cell growth in the breast’s milk-producing glands or scar-like tissue changes in the breast, can increase the risk of developing breast cancer

This increased risk can reach up to 50% in specific circumstances.

As benign and cancerous breast conditions have similar symptoms, people can panic as they do not have the expertise to tell the difference.  

Hence, it is advised to seek medical attention without any delay. 

Additionally, while doing breast exams or mammograms, it might pose a problem, as it will be difficult for your doctor to distinguish between cancerous and non-cancerous lumps. 

That is why you should know how your breasts usually feel and do a regular breast self-exam.

Conclusion

In conclusion, fibrocystic breast disease is a common benign condition that affects many women. 

The common signs are lumpy breast tissue, pain, tenderness, and swelling.

While the exact cause is yet to be determined, hormonal fluctuations, age, reproductive factors, lifestyle choices, genetics, and pre-existing conditions contribute to its development. 

While not harmful itself, it can increase the risk of breast cancer. 

So, you should perform regular breast self-exams and medical evaluations. They are essential for noticing any changes and detecting potential issues.

It is essential to get in touch with a healthcare professional if you notice any changes in the breast tissue, such as unusual lumps or skin abnormalities.

You will receive proper treatment by carefully seeking medical attention when necessary. 

This will enable the early detection of any potential concerns related to fibrocystic breast disease.
