what kind of cancer did danielle fisher have

Danielle Fishel was diagnosed with ductal carcinoma in situ (DCIS) , a very early form of breast cancer sometimes described as “stage 0” breast cancer.

She has further specified that it was high‑grade DCIS with microinvasion , meaning a very small area where cancer cells had just started to break beyond the milk duct, which some doctors classify closer to stage 1.

Her diagnosis and updates have been shared publicly through interviews and her podcast, where she emphasized that it was caught very early through routine mammography and that her outlook is positive.
