Did your recent mammogram report say 'Breast Calcifications'? When you saw that, you felt a little scared and nervous, didn't you? You must have thought, 'Oh, is this a sign of cancer?' It's actually normal to feel that way. But before you panic, let's be clear about this today. Because most of the time, this is nothing to be afraid of.
Simply put, what are breast calcifications?
This is caused by tiny deposits of calcium inside the breast tissue. Like dust particles. These are so small that you can't even feel them. They don't hurt. So you only know they're there when you have a mammogram. A mammogram is a special X-ray test that looks for abnormalities in the breasts.
These calcium deposits are usually harmless (benign) . However, very rarely, they can be an early sign of abnormal cell growth in the breast tissue. That's why doctors are concerned about them. By looking at the size, shape, and spread of these calcium deposits, your doctor can determine if they are normal or if further testing is needed to rule out cancer.
There are two main types of calcium deposits:
These can be divided into two main types based on how they appear on a mammogram. It will be very important for you to be aware of these two.
| Calcium type | What it looks like on a mammogram | Important information |
|---|---|---|
| Macrocalcifications (large calcium deposits) | They look like large, white dots scattered throughout the breasts. | These are the most common. They are usually benign . They do not require any special tests. |
| Microcalcifications (small calcium deposits) | They look like very small, fine white dots. They may be clustered together or arranged in a line. | These are also usually harmless. However, they are slightly more likely to be a sign of cancer than macrocalcifications. If you see something like this, your doctor may order further tests to confirm whether it is cancer. |
Why does calcium like this get deposited in the breasts?
There is no single cause for this, but it can occur as a result of various processes that affect breast tissue. These are usually benign calcium deposits that can be caused by:
- An injury to the breasts.
- Breast Cysts .
- Breast infections .
- Changes in the blood vessels of the breasts with age.
- Harmless breast tumors (Fibroadenomas) .
- Blockage of the milk ducts (mammary duct ectasia) .
- Previous breast surgery.
- Previous treatment for breast cancer.
Cancer-related calcium deposits often occur with a condition called Ductal Carcinoma in Situ (DCIS) . DCIS is a very early stage of breast cancer that begins in the milk ducts but has not spread (non-invasive).
The most important thing is that there is no relationship between the amount of calcium you eat (e.g., milk, yogurt, calcium tablets) and the calcium deposits in these breasts. So don't worry about what you eat.
How does the doctor diagnose this? What tests do they do?
This is usually first seen on a routine mammogram. If the radiologist reviewing the report is suspicious about the nature of these calcium deposits, that is, if they are in a cluster or in a line, they may recommend several more tests to make sure they are not cancerous.
- Diagnostic Mammogram: This is a little more detailed than a regular mammogram. It's like zooming in on a camera. It takes pictures of just the calcium deposits from different angles to study the shape and arrangement of the deposits.
- Biopsy: In most cases, a biopsy is needed to determine the exact cause of the calcium deposits. This involves looking at the images from the mammogram and using a special needle to remove a very small piece of tissue from the area where the calcium is and sending it to the lab for testing. This is also called a Stereotactic Biopsy or Core Needle Biopsy . This is the only way to tell with 100% accuracy whether there are abnormal cells or not.
Remember this before getting a mammogram!
Sometimes, substances in your deodorant, powder, or cream can cause white spots, such as calcium deposits, to appear on your mammogram. This can be unwarranted. So, don't apply anything like this to your armpits or breasts on the day of your mammogram. If you accidentally apply it, wipe it off before the test.
Do these calcium deposits need to be treated?
The answer is often "no." Most of these are harmless and do not require any treatment. Your doctor will compare the new image with the old one the next time you have a mammogram. That is, to see if the calcium spots have changed.
However, if the tests confirm that these calcium deposits may be a sign of cancer, the treatment will not be for the calcium deposits, but for the cancer cells that caused them. At that time, you will be referred to a breast surgeon. Treatment options may include:
- Surgical removal of part of the tissue or the entire breast.
- Radiation and/or chemotherapy.
- Targeted drug therapy.
You can discuss this with your doctor and choose the treatment that best suits you.
Should I really be afraid of this?
In short, most of the time, there's no reason to worry. These are usually harmless. Although they're rarely a sign of cancer, it's a good thing that a mammogram can detect them at a very early stage . Because the earlier they're detected, the better the chance of a full cure with treatment.
Studies show that even the most suspicious calcium deposits that are referred for further testing turn out to be benign . Also, about half of all breast cancers without a detectable tumor have these small calcium deposits (microcalcifications). This means that finding them on a mammogram is extremely important for detecting early-stage cancers like DCIS.
There's no way to prevent these calcium deposits from forming, but getting regular mammograms is the best way to catch cancer early if it develops.
