In mammography, breasts are imaged using X-rays. For this purpose, the breasts are pressed between two firm surfaces and then black and white images are taken with the help of X-rays. These images are displayed on a computer screen so that the doctor can look for signs of breast cancer.
In general, mammography is a safe and effective way to diagnose breast cancer. Although this diagnostic method exposes people to small amounts of radiation, it usually does no harm unless the person does it frequently. In this article from BingMag Meg, we examine mammography and its association with cancer. Join us.

What is the purpose of mammography?
This method Imaging is used for screening or diagnostic purposes. Screening mammography In women who have no signs or symptoms of cancer, screening mammography is used to check for breast tissue changes. Is used. The goal is to detect breast cancer before it has spread to other parts of the body. It is used for the presence of a lump, pain and thickening of the nipple or discharge. Also, if the result of the screening is abnormal, this type of mammography is recommended, during which more images of the breasts are taken.
- Is it possible to diagnose cancer with a blood test?
Mammography is a type of imaging in It uses low-dose X-rays to take pictures of the breast. Exposure to radiation can increase the risk of cancer. Exposure to radiation is one of the risks of mammography, according to the National Cancer Institute (NCI). The risk increases when a person is frequently exposed to X-rays in the chest area.
Researchers studied the effects of mammography annually or biennially on women aged 40 to 74 years. The results show that repeated use of this method can increase the risk of breast cancer, and this risk is higher for those who have larger breasts.
However, the researchers noted that the benefits of mammography in screening Breast cancer and early detection of this disease outweigh its potential risks. Using this method helps reduce the number of deaths due to breast cancer. If you are worried or have questions about the possible dangers of mammography, you can talk to your doctor.
Is mammography safe?
This imaging method is safe and secure. The NCI, the American Cancer Society (ACS), and other scientific institutions support regular mammography screening to help diagnose breast cancer. The amount of radiation used in this method is less than the standard and is in a safe range for everyone.

Benefits and risks of mammography
- They are more likely to be diagnosed with breast cancer early.
- They may need invasive treatments such as surgery Are less likely to be found.
- These people are more likely to be successfully treated for cancer.
Some of the potential risks and disadvantages of mammography include:
- False positive result: This problem occurs when a person does not have cancer, but the radiologist notices changes in the breast tissue. This can make a person anxious and put extra tests on him. False positives appear to be more common in young women, those with dense breasts, people who have had a breast biopsy in the past, and people with a family history of breast cancer. This problem is also more common in women taking estrogen.
- Extreme Diagnosis: Mammography can detect non-invasive, benign tumors that do not require treatment. However, it is difficult for doctors to distinguish these types of tumors from tumors that need treatment. As a result, they usually cure all of them.
- False negative result: In about 20% of cases, a person may have breast cancer but mammography may not be able to diagnose it. This problem usually occurs when the mass is very small or located in certain areas such as the armpits. False-negative results delay the diagnosis and treatment of the disease.
- Not all breast cancers can be cured, and a quick diagnosis does not reduce the risk of death: Some types of lumps grow very quickly. As a result, the cancer may have spread to other parts of the body at the time of diagnosis.
At what age should we start mammography?
There are no specific instructions on when to start a mammogram. On the other hand, the suggestions made by different scientific organizations can be different. The US Preventive Services Working Group recommends that women aged 50-74 be screened for breast cancer every two years. The group also recommends people in their 40s and 40s talk to their doctor about the potential benefits and risks of mammography. Perform mammography screening. But people aged 54-45 must be screened annually. The association recommends biennial screening for women 75-55 years. Breast cancer screening should continue for as long as a person is expected to be alive for the next 10 years.
In general, risk factors for breast cancer can affect the age at which mammography begins. For this reason, the doctor will determine the age at which the screening begins, depending on the individual's condition. Factors that increase the risk of breast cancer and therefore the need for screening include:
- Age over 50
- Past history of breast cancer >
- Family history of breast cancer
- Breast tissue density
- Personal factors such as the onset of menstruation before age 12 and the onset of menopause after age 55
- History of Radiation Therapy in the Past
Other Misconceptions About Mammography
There are many misconceptions and misconceptions about this imaging technique, some of which are listed below:/p>
Mammography can detect all the early signs of breast cancer
The fact is that no test is complete. On average, mammograms do not detect about 20% of breast cancers. The denser the breast tissue, the more likely it is that this problem will occur. In women with dense breast tissue, other imaging techniques, such as ultrasound and MRI, may be used in addition to mammography.
If the mammogram is negative, it does not need to be repeated every year.
Many scientific institutions, including the American Cancer Society, regardless of the negative test of the year Previously, annual screening was recommended for people aged 54-45. The risk of breast cancer in women in this age group is moderate. If the screening test is positive, the person should talk to their doctor about the next steps in the diagnosis.
I have no family history of breast cancer and no signs of cancer, so I do not need to be screened
More than 75% of women with breast cancer in their family do not have a history of the disease. Therefore, all women should start breast cancer screening at a certain age, regardless of symptoms or family history. Early detection of this disease is very important. If you wait to see the symptoms of breast cancer, the disease may progress to other parts of the body.

3D mammography is similar to traditional 2D mammography
3D mammography is the most advanced method that helps in screening and diagnosing breast cancer. This imaging technique gives us clearer images of the breast than traditional two-dimensional mammography. The three-dimensional method is more capable of distinguishing normal tissue from cancerous tissue. Using this method increases the risk of early detection of cancer by 40% and the probability of a false positive result by 40%. . However, the amount of this radiation is limited and does not cause cancer unless you do it frequently. The benefits of this method in early detection of breast cancer outweigh the possible side effects.
Current guidelines recommend different ages for starting breast cancer screening. Depending on your circumstances, your doctor may decide to start mammography screening at age 40 or 50 or even younger.This is for educational and informational purposes only.
