Sonogram (Definition)

An ultraound, also known as a sonogram, is a painless and relatively inexpensive imaging test that utilizes sound waves instead of ionizing radiation. There are no side effects. Ultrasound can give us two-dimensional, and in some applications three-dimensional, images of structures and organs in virtually any part of the body. In addition to diagnostic uses, such as evaluating abnormalities in the abdomen, pelvis, and breast, ultrasounds are commonly used to guide needle and catheter placement in a variety of surgical ...Read more

Can I find out if a breast cyst / tumor is malignant through a breast ultrasound and mammogram?

Can I find out if a breast cyst / tumor is malignant through a breast ultrasound and mammogram?

Sometimes.: There are lesions that can be determined with a high level of assurance to be benign and lesions that can be determined to be malignant. There are also many lesions that cannot be determined with a high degree of certainty with these sstudies alone.

Had a breast cyst monitored every six months. Now mammo say it has undefined borders. Going for follow up mammo and ultrasound. Cancer likelihood?

Had a breast cyst monitored every six months. Now mammo say it has undefined borders. Going for follow up mammo and ultrasound. Cancer likelihood?

Hard to make: A determination with limited info and no images, but it sounds like it now has some suspicious features and may require needle biopsy. That said, the probability of cancer is probably relatively low, but not low enough to keep following it due to the interval change.

Abnormal cells found in breast cyst on cytology. Cannot be seen on ultrasound due to aspiration so cannot do biopsy. Would MRI help?

Abnormal cells found in breast cyst on cytology. Cannot be seen on ultrasound due to aspiration so cannot do biopsy. Would MRI help?

Yes.: If the MRI is negative the likelihood of cancer is less than 2%. If an MRI is not obtained, a follow up ultrasound examination should be obtained and, if the cyst recurs, a core needle biopsy of it may be indicated. I assume you have had a mammogram? If not, one should be obtained.

Radiologist says possibly benign from ultrasound septated left breast cyst 1.4cm x 2.8cm. No solid Nodule and no internal flow. Is this serious? /bad

"Probably benign": Is the BIRADS classification (category 3)you are referring to. By definition, this implies a chance of malignancy less than 3%, and practically speaking it is probably more like 1%. The standard recommendation for a category 3 lesion is short interval follow up. Many consider a septated cyst a BIRADS 2 (benign) lesion requiring no follow up, so the overwhelming probability is that you will be fine

Does a breast cyst always need a needle biopsy radiology doc just suggest to do a follow up u/s and mamm in 6 months to make sure cyst has not grown?

Does a breast cyst always need a needle biopsy radiology doc just suggest to do a follow up u/s and mamm in 6 months to make sure cyst has not grown?

No: A simple breast cyst or cyst with a single thin septation is very common and does not require biopsy or follow up. If it has a more suspicious feature (such a internal nodule, thick septation, etc.), then biopsy would be preferable to follow up. If a breast cyst is benign in appearance, it can still be therapeutically drained under ultrasound guidance to relieve symptoms.

Breast cyst popped like a pimple would. Is this normal?

Breast cyst popped like a pimple would. Is this normal?

Cyst: Your breast is covered with skin and therefore skin issues will occur. As long as the area is not red, firm, painful, it was most likely a sebaceous cyst.

What does normal breast tissue feel like? Or breast cyst? I don't know if im feeling a lump or just normal. Its movable, feels connected to tissue.

What does normal breast tissue feel like? Or breast cyst? I don't know if im feeling a lump or just normal. Its movable, feels connected to tissue.

See answer: Tough to answer over the computer. Fibro-cystic breast disease is very common in young breasts, and is probably what you are feeling. The best advice for you is too a dr. And get a breast exam, and have the dr. Explain what is normal specifically to your breasts, and then when you perform an exam on yourself at least monthly, and notice any changes, you can alert the dr. Best wishes.

Yes: This can occur. They may also just go away without overtly "rupturing".

Can it hurt to get a breast cyst drained?

No: The breast is given a local anesthetic, a small needle is inserted and the fluid is aspirated. The fluid is sent to the lab for evaluation. The whole procedure can be performed in the office.

Is a breast cyst that enlarges about every 6 months deadly.

Is a breast cyst that enlarges about every 6 months deadly.

Probably not serious: Breast cysts are almost always benign and not deadly at all. Especially if painful, a breast cyst should be aspirated with a needle (usually an office procedure). The fluid can be sent for pathologic analysis but that can be confusing as benign cyst fluid contains cells that can be confused with malignant cells. If cysts continue to recur after aspiration, they should be excised.

Short term follow-up: Birads 3 usually refers to "probably benign" and requires short term follow up, usually with a "diagnostic" mammogram and ultrasound if needed. If something remains suspicious, they will recommend a biopsy. Definitely follow up! Best wishes.

Can fibrocystic breast cyst occur in one breast with discharge?

Can fibrocystic breast cyst occur in one breast with discharge?

Yes: Fibrocystic breast changes and symptoms can often be felt more on one side than the other or only on one side. The discharge should be clear or yellowish. You should never see blood, as this is definitely abnormal and needs to be checked out. If you feel a lump or think you have a cyst, a sonogram should be performed to confirm that it is a fluid lump and nothing solid.

Might it be that a a breast cyst be caused by a hormonal imbalance?

Might it be that a a breast cyst be caused by a hormonal imbalance?

Usually not: The cause of breast cysts is unknown. There is some investigation ongoing into whether estrogen is involved. Breast cysts are very common, and usually benign. Make sure yours is evaluated by your physician.

Which is the percent of probability than a breast cyst change in cancer? Thanks

Very little to none: Fibrocystic disease is very common in young woman, itself is not premalignant, but has slightly higher incidence of cancer, cyst itself will not turn to cancer

Cyst (Definition)

A cyst is a structure or mass that consists of a cellular lined sac. It is typically filled with fluid but may be filled with solid material. It can be congenital, traumatic, or acquired. They may develop nearly anywhere in the body and usually require complete excision for eradication or they are likely to recur. Fluid filled sacs that are not cellular lined ...Read more
