Symptoms of DCIS
Most women with DCIS have no symptoms and only find out they have it when it’s found on a mammogram.
Because more women are having mammograms as part of the National Breast Screening Programme, DCIS is now diagnosed much more often.
A small number of women with DCIS have symptoms such as:
a breast lump
fluid (discharge) coming out of the nipple
a rash (like eczema) on the nipple.
Paget’s disease of the breast
Paget’s disease is a condition that begins in the breast ducts. It causes redness and itching in the nipple and the darker area around it (areola). Women who have Paget’s disease may have underlying DCIS or an invasive breast cancer.
