Fibroadenoma: Basic Information

Fibroadenoma is a kind of a solid, non cancerous breast tumour which tends to occur basically in teenage girls or women under the age of 30 years. Fibroadenoma can also be described as firm, smooth or rubbery tumours which are well defined in shape and size. Upon touching, these might feel like a small marble under the skin when they are touched. They can vary in sizes and shapes. These tumours can heal on their own.

Most of the Fibroadenoma are is between 1 to 3 cm in size. In some of the rare cases, they can grow to about 5 cms and are known as giant fibro adenomas. When found in teenagers, they are known as juvenile fibro adenomas.

Fibroadenoma is rated as one of the most common kinds of breast lumps which are found in the breasts. The treatment options for these can include monitoring the breasts in order to look for the changes in the size of the lump or a biopsy in order to check the lump. This is mostly followed by corrective surgery in order to remove the lump. 

Causes of Fibroadenomas:

There are no definite causes for Fibroadenomas. However, doctors have been able to link reproductive hormones to the disease. Fibroadenomas are known to occur greatly during the reproductive years of women and then tend to grow bigger in size during pregnancy or when a person is using hormone therapy. Fibroadenomas shrink after menopause, when the normal hormone levels decrease to a bare minimum.

Estrogens have known to play a major part in the growth of Fibroadenomas. If a woman indulges in taking oral contraceptives before the age of 20, then she is at a higher risk of contracting the condition.

Signs and Symptoms of Fibroadenomas:

Fibroadenomas are known to be solid breast lumps and masses which have the following characteristics:

  • ü  Round with a distinct borders
  • ü  Easily movable
  • ü  Firm and rubbery in nature
  • ü  Painless and hard

Often on pressing, Fibroadenomas feel like a hard marble underneath the skin. A person may have more than one Fibroadenomas. Their size ranges from ones that are too small to the ones which can be felt and can be detected with the help of a mammogram or an ultrasound.

Fibroadenomas tend to decrease on their own once a woman reaches menopause.

If any normal breast tissue of your body feels lumpy, it is recommended to see a doctor immediately regarding that. 

Tests and Diagnosis of Fibroadenomas:

A doctor usually goes for a physical examination in order to check both the breasts for the presence of any lumps. However, apart from the physical examination, some of the other tests for diagnosing Fibroadenomas are as follows:

  • Mammography: This technique uses X rays in order to project an image of the suspected areas where the lumps are found. The Fibroadenoma appears on the mammogram as a smooth, round edges which are different from the underlying breast tissue.
  • Ultrasound: If a person is less than the age of 30, then an ultrasound is done in order to check for the presence of Fibroadenomas. In younger women due to the presence of dense breast tissue, it becomes very difficult to check for Fibroadenomas. An ultrasound helps the doctor in order to determine if the lump is solid in nature or is filled with fluid. A solid mass is most probably a Fibroadenoma, while a fluid filled one will be a cyst.
  • Fine Needle Aspiration: In this, a thin needle is inserted into the breast and the contents of the lump are taken out. If fluid present, then it is mostly a cyst.
  • Core Needle Biopsy: After the physical examination and the imaging of the breast, sometimes a core needle biopsy is conducted. In this test, a larger needle is used to collect the tissue samples from the lump in order send for the analysis.

Treatment and Drugs for Fibroadenomas:

In a lot of cases, Fibroadenomas heal out on their own and do not need any treatment. However, in some of the other cases, surgical operation can be done in order to remove the Fibroadenomas.

Non Surgical Management:

If Fibroadenomas are detected, with the help of breast exams, imaging tests as well as the biopsy, the non surgical treatment options can be prescribed. Fibroadenomas can be easily moderated with the help of follow up’s with the doctors regularly. Ultrasounds can be done in order to keep a tab on the shape and the size of the tumours.


Sometimes, surgery is done in order to remove the Fibroadenomas. The procedures for the removal of Fibroadenomas are as follows:

  • Lumpectomy: In this, a procedure is done in order to remove the affected breast tissue and is sent to the lab in order to check for cancer.
  • Cryoablation: in this procedure, the doctor inserts a thin device through the skin to the lump. A gas is used in order to freeze the affected tissue. If the lump is too large to be frozen, then cryoablation is used in order to make the diagnosis is done certainly.

After the lump has been removed, there are chances that new lumps may develop over the passage of time. New lumps should be checked with the help of mammograms, ultrasounds or with the help of the biopsy in order to check for any cancerous formations.
