Understanding DCIS

Find out how DCIS is diagnosed, treated and how it might affect your life.

  • What is DCIS?

    Ductal carcinoma in situ (DCIS) is the earliest possible form of breast cancer. It needs to be treated but is not life-threatening.

  • The breasts

    Breasts are made up of fat, supportive (connective) tissue and glandular tissue containing milk lobes.

  • DCIS and invasive breast cancer

    If ductal carcinoma in situ (DCIS) is not treated, it may spread into (invade) the breast tissue surrounding the ducts.

  • Signs and symptoms of DCIS

    Most women with DCIS have no symptoms and are diagnosed through NHS Breast Screening Programmes. A small number of women do have symptoms.

  • How is it treated?

    There are five main types of cancer treatment. You may receive one, or a combination of treatments, depending on your cancer type.
