However, because it can progress into an invasive breast cancer, which can be life-threatening, it is usually treated with surgery, or surgery and radiation therapy. The number of women being diagnosed with DCIS is increasing because it is picked up by breast screening programmes.

Researchers from the Netherlands Cancer Institute say their results should provide reassurance to women who are diagnosed with the disease.

Led by Dr Jelle Wesseling, a breast pathologist at the Netherlands Cancer Institute, the team studied data on almost 10,000 Dutch women who were diagnosed with DCIS between 1989 and 2004. They tracked the patients over an average of 10 years and compared their death rates with the expected mortality in the general population.
