    What is a mammogram?

    A mammogram is an X-ray of the mammary glands in the breast. The diagnostic test reveals breast problems, such as lumps and whether any lump is a fluid-filled cyst or a solid mass. Here are some facts about mammograms you might not be aware of.

    Breast cancer screening is not all about mammography.

    Mammograms screen for breast cancer, tumours and calcium deposits. However, monthly breast self-examination and regular doctor's examinations are also required for optimal breast cancer screening.

    An abnormal mammogram is not always cancer.

    If your mammogram is abnormal, a breast problem is quite likely. However, it does not necessarily mean that a cancer is present. Also, it doesn’t mean they are ineffective. This is the reason other tests including biopsy are followed by an abnormal mammogram.

    Radiation exposure during a mammogram does not cause cancer.

    Radiation exposure is linked to cancer. But,radiation exposure during a mammogram has never been found to be a cause of breast cancer. Mammograms require very small doses of radiation, and the risk of cancer due to it is low.

    Finding can differ because of antiperspirants or deodorants.

    It is advised to not wear antiperspirants, deodorants and powders before you go for a mammogram. These make interpretation of the results difficult or make the images appear foggy. And, an abnormal finding can be taken for breast cancer.

    Breast implants can make a mammogram difficult.

    If you have breast implants, it is advised to tell the expert who is performing the mammogram about it. These can make a mammogram more difficult by getting in the way of breast tissue. This is why mammograms are more difficult in younger women as they tend to have denser breast tissue.

    A specific gene can raise the risk of breast cancer from mammogram.

    According to the British Medical Journal, women who carry a specific gene mutation called BRCA 1/2 are vulnerable to radiation exposure from mammography. This gene mutation is linked to cancer development.
