When breast cancer is diagnosed, it’s natural for thoughts to go straight to treatment. But for some early cancers, is prompt treatment — or sometimes, any treatment at all — the only path worth considering?
That’s a question medical experts are exploring with ductal carcinoma in situ (DCIS). This very early form of breast cancer makes up around 25% of breast cancer diagnoses.
DCIS is cancer cells that are found in a duct in the breast that haven’t moved outside of the duct to surrounding tissue. DCIS is sometimes referred to as noninvasive, preinvasive or stage 0 breast cancer.
