This exam uses low-dose x-rays to make a picture of breast tissue. The picture is called a mammogram. Mammograms are used to:
• Detect breast cancer
• Identify changes in the breast tissue before a lump can be felt
• Find a lump's location before a biopsy or surgery
• Yearly mammograms are recommended starting at age 40.
• Annual clinical breast exams are recommended for women 40 and over
• For women in their 20s and 30s, exams every two or three years are recommended.
• Women should know how their breasts normally feel and report any breast change promptly to their health care providers.
• Women who have three or more relatives with breast cancer, or any relatives with ovarian cancer, should consider having an MRI and a mammogram every year. Women who have fewer than three releatives with breast cancer should talk with heir physicians about the benefits and limitations of adding MRI screening to their yearly mammogram.
What happens during a mammogram?
You will stand in front of a special x-ray machine. It has a platform to place your breast on. The technician will adjust the height of the platform. One breast will be lifted and placed between special plates that hold film. The plate is brought close to the platform and compresses the breast. This allows for a clearer image. The exam will cause some discomfort. Tell the technician if you feel any pain. Two pictures of each breast are taken. During one, you face toward the platform and the image is taken looking down at the breast. For the second, you stand beside the machine. This allows for a side view. The x-rays are done on the other breast. Extra images may be needed if you have implants or if the doctor is looking at a specific spot more closely.
