Breast cyst will cause breast cancer?
Breast cyst will cause breast cancer? Most breast cysts are benign and will not induce breast cancer. It is usually more common in women aged 40.
Breast cysts are round or oval structures and are filled with fluid. About 25% of all breast masses are cysts. Most breast cysts are benign and do not increase the risk of breast cancer.
They can be very small, or they can be large enough to pass skin sensory or imaging tests (very obvious cysts or large cysts). Many cysts fall in between.
Cysts can occur at any age, but for women in their 40s, they are most common. In more than half of the cases, women will develop multiple cysts over a period of time. If the cyst is large enough to be felt, it is usually round and relatively mobile under the skin. Cysts can also cause breast pain and tenderness. These symptoms may worsen at different points in the menstrual cycle.
Diagnosis of cysts
When diagnosing a cyst, the doctor wants to figure out whether it is simple, complicated, or somewhere in between. Ultrasound imaging can be used to determine this.
Simple cysts have smooth, thin, regular-shaped walls and are completely filled with fluid. The sound waves from the ultrasonic test pass through them, indicating that there is no solid area. Simple cysts are always benign.
Complex cysts have irregular or fan-shaped borders, thick walls, and some evidence of solid areas or fragments in the fluid. These solid areas echo the sound waves of ultrasound. Sometimes complex cysts are sucked out or discharged with a fine needle to test the fluid inside. If blood or any unusual cells are present, further testing may be needed to rule out breast cancer.
Complex cysts are somewhere between simple and complex. Although they have most of the features of simple cysts, they often have some fragments inside and echo some ultrasound. However, they do not have the thick walls or obvious solid components of complex cysts.
For complex cysts, doctors want to rule out any possibility that the solid area contains cancer cells. In this case, a biopsy may be required.
Treatment and follow-up
For simple cysts, unless the cyst is particularly large, uncomfortable or painful, no treatment is needed. The cyst can then be drained with a fine needle. If the cyst recurs, it can be reassessed with mammograms and ultrasound, and it can be drained again. Most women with simple cysts will go back to routine breast cancer screening.
For complex or in-between cysts, once imaging confirms that the growth is a cyst, the follow-up plan is usually the same. In certain situations, your doctor may recommend fine needle aspiration to empty and check the fluid inside. Or they will require follow-up every 6-12 months, 1 to 2 years to check the cyst. Normally, you can perform clinical breast examinations and ultrasound examinations, with or without mammography.
If at any time your doctor thinks the cyst has suspicious features, indicating that it may actually be breast cancer, the doctor can perform a biopsy to make sure that any solid part of the cyst is benign. Your doctor may use ultrasound to guide the core needle into the cyst and take a tissue sample under a microscope for examination. In rare cases, it may be necessary to remove the cyst (resection biopsy).
If you have multiple cysts or frequent new cysts, you may consider a follow-up by a breast specialist. Cysts are accompanied by other risk factors for breast cancer, such as a clear family history, which causes many women to do so. Although cysts do not increase the risk of breast cancer, it is reassuring to be followed up by a breast specialist.
