Do you know when your next mammogram will be? The skilled physicians that make up the Women’s Specialists of Plano offer the following information for those who are new to the mammogram process. What are the Recommendations for Screening Mammograms? According to the National Cancer Institute, “Women age 40 and older should have mammograms every 1 to 2 years. Women who are at higher than average risk of breast cancer should talk with their health care providers about whether to have mammograms before age 40 and how often to have them.” What is a Mammogram? A mammogram is used to check for breast cancer in the breast. It is an x-ray image and will show if there is any sign (such as a tumor, mass, lump in the breast, etc.) of cancer as well as if the breast tissue appears normal. A mammogram can be done digitally or via film. This common mammogram procedure is also referred to as a screening mammogram where several images are taken of each breast. The images help physicians screen for breast cancer when lumps cannot be felt externally. When a mammogram is ordered because a woman has felt a specific lump in the breast, or because she has another symptom, then it is referred to as a diagnostic mammogram. This mammogram is helpful in order to rule out cancer; oftentimes these lumps are benign cysts or tiny deposits of calcium. A diagnostic mammogram takes longer to perform than a screening test because more images and x-rays are needed and they are typically taken at a variety of angles. Diagnostic mammograms are also used on women where screening becomes more challenging; such as in the instance where breast implants are in place.  What are the Benefits of Screening Mammograms?Most women will have their first screening mammogram around age 40; at this young age, early detection ofbreast cancer can often be seen with screening mammography alone. For women who have a history ofbreast cancer in their family, or who have a history of cysts and benign lumps, and for those who have hadbreast augmentation, a diagnostic mammogram may be ordered from start.Is there a Downside to a Screening Mammogram?A screening mammogram does not necessarily mean that cancer will be found. These mammograms candetect cancerous tumors that often cannot be felt by touch (such as a lump in the breast), but in 20% of thecases, screening mammograms will miss breast cancers that are present. 

False-Negative Results vs. False-Positive Results—What Does This Mean?False-negative mammogram results occur when cancer exists within the breast at the time of screening,but it is not caught during the screening mammogram. False-negative results occur in younger womenmore so than older women because younger women have higher breast density—which is the primarycause of a false-negative result. On the other hand, older women will have more fatty tissue in thebreast. High-density breast tissue, as well as tumors, will show up as white on the x-ray, whereas fattytissue is dark making it easier to detect a true cancer cell. False-positive mammogram results occurwhen a physician or radiologist concludes that a mammogram is abnormal, even though no cancerexists. To conclude a false-positive mammogram, further analysis will need to occur to rule out cancer.This is done usually with a diagnostic mammogram, an ultrasound or a biopsy.What are the Benefits of Screening Mammograms?Most women will have their first screening mammogram around age 40; at this young age, earlydetection of breast cancer can often be seen with screening mammography alone. For women whohave a history of breast cancer in their family, or who have a history of cysts and benign lumps, and forthose who have had breast augmentation, a diagnostic mammogram may be ordered from start.Can the X-Ray Imaging from Mammograms Cause Cancer?This is a concern for many women. Although repeated exposure to x-rays can be harmful, mammogramsrequire just a very small dose of radiation. Exposure is low and the benefits of receiving a mammogramcompletely outweigh the risks of this exposure. It is very important that woman alert their health careprovider if there is any possibility they are pregnant as this could be dangerous for the unborn fetus.What is Digital Mammography?Advances in technology have produced digital mammograms, in which the images taken arecomputerized and shown on a screen, rather than recorded on film using an x-ray cassette. This allowsfaster and more accurate stereotactic biopsy, and reduces the patient’s discomfort, requiring her toremain still for a shorter period of time. Digital mammography is still in its infancy, but some studies haveshown that women with denser breasts, post-menopausal women, and women under the age of fortymay benefit from digital mammograms. Otherwise, the digital images are said to be “comparable” at thisstage with traditional film images.What are the Risks for Developing Breast Cancer?According to the National Cancer Institute, women who exhibit the following traits are at an increased riskfor developing breast cancer:• Age—as a woman ages, her chances for developing breast cancer increase• A personal history of breast cancer• A family history of breast cancer• Hereditary genes (For example, BRCA1, BRCA2, and others)• High breast density• Reproductive and menstrual history—Women who had their first menstrual period before age 12 or who went through menopause after age 55 are at an increased risk of developing breast cancer. Women who had their first full-term pregnancy after age 30 or who have never had a full-term pregnancy are also at increased risk of breast cancer.• Long-term use of menopausal hormone therapy—(those who have combined estrogen and progestin hormone therapy for more than 5 years).• Exposure to radiation• Excessive use of alcohol• A heavy body weight/obesity The Women’s Specialists of Plano offers• Lack of exercise.  mammogram, sonogram and 3D-imaging services in-  office.
