Can a breast cyst become câncer?

The breast cyst, also known as breast cyst, is an almost always benign alteration that appears in most women between 15 and 50 years of age. Most breast cysts are of the simple type and, therefore, are filled only with liquid, not posing any he alth hazard.

However, there are two more main types of cysts:

  • Thick breast cyst: contains a thicker, gelatin-like fluid;
  • Solid content breast cyst: has a hard mass inside.

Of these types of cyst, the only one that presents some risk of becoming cancer is the solid cyst, which can also be known as papillary carcinoma, and which needs to be evaluated through biopsy to identify if there are cancerous cells inside..

Most of the time, the cyst does not hurt and is hardly noticed by the woman. In general, a breast cyst is only noticed when it is very large and the breast becomes more swollen and heavier. See all symptoms here.

How to diagnose breast cyst

Breast cyst can be diagnosed through breast ultrasound or mammography, and does not require specific treatment. However, women who have a very large cyst that causes pain and discomfort may benefit from a puncture to remove the fluid that forms the cyst, ending the problem.

It is also important to have regular breast self-exams. Watch the following video and see how to do it correctly:

When the breast cyst can be serious

Almost all breast cysts are benign and therefore the risk of developing cancer from this change is very low. However, all solid cysts should be evaluated by biopsy as they carry some risk of being cancer.

In addition, the cyst can also be analyzed by biopsy if it is increasing greatly in size or if there are symptoms that could indicate cancer such as:

  • Frequent itching of the breast;
  • Liquid release from the nipples;
  • Increase in size of one breast;
  • Changes in the breast skin.

In these cases, it is very important to go to the doctor for further examinations of the cyst and even assess whether there is a possibility that a cancer is developing that is not related to the cyst, for example.

Even if all tests indicate that the cyst is benign, a woman should have a mammogram 1 to 2 times a year, according to her doctor's advice, as she continues to present the same risk as any other woman of having breast cancer.
