Fibroadenoma: learn all about the tumor that affects younger women

Keeping your exams up to date and routinely monitoring your health is very important for women. Some problems can be diagnosed through this care and be treated more efficiently with early diagnosis, such as the presence of a fibroadenoma.

Fibroadenoma is a type of breast lump that is considered a benign tumor. According to Dr. Angela Cassol, the lump appears more commonly in women up to 30 years old and it can be noticed through palpation of the breast, being more sensitive during the menstrual period.

Fibroadenoma: causes

The causes of the appearance of fibroadenomas are related to female sex hormones. As these hormones multiply, new glandular cells are formed.

However, don’t worry: these hormonal variations are normal during a woman’s life. The formation of fibroadenomas is also considered common. About 150,000 cases are recorded per year.

Symptoms of Fibroadenoma

  • Lump in the breast or armpit;
  • Mobile nodule.

Normally, fibroadenomas do not cause pain. However, it is possible to feel them through touch. Especially during the menstrual period, when the breasts are more sensitive.


When noticing the presence of the lump in the breast, through self-examination, it’s time to look for a doctor.

From this, the mastologist will perform specific tests, such as physical examination, mammography, breast ultrasound and even a biopsy of the lump.

These tests vary according to the age and size of the lump. Most nodules do not need to reach the biopsy stage.

Therefore, it is important to look for a trusted doctor who will put you at ease and bring you more peace of mind during the process.

Fibroadenoma: treatment

In most cases, fibroadenomas do not require treatment. The doctor in charge assesses whether the lump can cause more problems for the woman. If the result is negative, he will recommend that the patient follow up every six months and monitor the development of the nodule.

As we said, it is possible to remove it through surgery, if the patient wishes. Many women choose this method for reasons of aesthetics and prevention.


Surgery to remove fibroadenomas in the breast is simple and usually occurs quickly.

In this way, it is recommended by the doctor in charge when one of the tests requested presents abnormal results and/or the nodule causes discomfort for the patient.

Surgery is performed under local anesthesia, except when more than one nodule is removed. In this case, anesthesia is general.

But it is worth remembering that surgery is recommended only in specific cases. It is important to talk to your doctor and know your need.

Can Fibroadenoma Become Breast Cancer?

The likelihood of fibroadenoma becoming breast cancer is very low. This can usually happen when there is the presence of malignant cells in the nodule. However, it is not a trivial thing. The chances of that happening are low.

Despite this, for women who have already had fibroadenomas, the likelihood of getting breast cancer is slightly higher.

In addition, women who have more severe fibroadenomas, with calcifications and even abnormal cysts, may have a greater chance of acquiring breast cancer.

Even with the low chances of progressing to cancer, it is important that the woman is attentive to her body and follows up with her doctor.

It was concluded that fibroadenomas, in general, do not present great risks to women’s health and it is possible to live with their presence. But you must be aware of the changes in your body.
