Spotting What Mammograms Miss: MBI -- Research Summary

BACKGROUND: About one in every eight women in the United States will experience breast cancer in their lifetime. Each year approximately 200,000 women will be diagnosed with breast cancer and around 40,000 women will die from it. Second to lung cancer, breast cancer is a major cancer that will cause deaths (Source: National Breast Cancer Association).

SELF EXAMINATION: Nearly 70 percent of all breast cancers are found through self-exams and with early detection the 5-year survival rate is 98 percent. Researchers believe that taking a few minutes every month to perform a self-examination can make a lifetime of difference. Breast self-exams can be performed lying down, in the mirror, or in the shower to make sure you are doing it correctly. Women should start performing self-exams as early as the age 20. If a lump is found, then you should call the doctor for an appointment, eight out of 10 lumps are not cancerous.

THE NEXT STEP: Starting at the ages between 20 and 39, women are strongly suggested to get clinical breast exams every three years. By the age of 40 they should be getting baseline mammograms annually, especially if breast cancer runs in their family.
  • Mammograms. A mammogram is an x-ray picture of the breast. They can be used to check for breast cancer in women who have no signs or symptoms, usually referred to as screening mammograms. The machine can detect tumors that cannot be felt during a self-exam and deposits of calcium that shows the presence of breast cancer. The machine can also be used to look more closely at an already detected lump, called diagnostic mammogram. Signs of cancer include pain, skin thickening, nipple discharge, or a change in breast size or shape. Mammograms is also associated with potential harms, including false-negative results, false-positive results, the diagnosis and treatment of cancers and ductal carcinoma in situ lesions that would not have caused symptoms or threatened a woman’s life (over diagnosis and overtreatment), and radiation exposure (Source: www.National Cancer Also sometimes it is difficult to get a clear x-ray because of special circumstances like breast implants or women with dense breast tissue. Often it cannot tell the difference between a tumor and dense breast tissue because they both appear white.
  • Molecular Breast Imaging. Molecular Breast Imaging is a new technique used to detect cancerous tumors that are not always visible in a mammogram. A woman is injected with a radioactive isotope. It accumulates in tumor cells more than it does in normal cells and the tumor then appears dark in a radiation detecting camera and is easy to see. The procedure takes about 45 minutes for both breasts and does expose the patient to more radiation than mammography does. However, a Mayo Clinic study found that MBI detected three times as many cancers in women with dense breast tissue and an increased risk of breast cancer than a mammogram did. Also demonstrated fewer false positives, meaning the results appear abnormal but are noncancerous. 
WARNING: Only a few centers in the US are using the MBI approach, because it is limited to research. Researchers are working towards reducing the amount of radiation the patient is exposed too. Only one MBI does not put off much, but if it is going to be used annually then radiation needs to be reduced (Source: MORE
