    Screening for breast cancer

    Dr Eli Van Houten talks about the DIET technique and mammography in screening for breast cancer.

    Eli and his team are using digital cameras to image the elasticity (or stiffness) of breasts. Cancerous tissue can be ten or up to 100 times stiffer (or less elastic) than normal tissue. Traditional mammograms measure the (radio) density of breast tissue. The density of cancerous and healthy tissue doesn’t always vary much. Another advantage of the DIET technique is that it will make breast examination a much more comfortable procedure.

    By the end of this activity, students should be able to:

    • gather, evaluate and synthesise information across a range of texts and media
    • use content-specific vocabulary to understand texts
    • discuss ways in which cancer cells differ from normal cells
    • discuss different methods of screening and diagnosing some types of cancer
    • consider some of the advantages and disadvantages of the various methods used to screen for breast cancer.
