WASHINGTON — "Boy Meets World" star Danielle Fishel has revealed she's been diagnosed with an early form of breast cancer. Fishel made the announcement on Monday's episode of the "Pod Meets World" podcast she co-hosts with fellow "Boy Meets World" alums Rider Strong and Will Friedle. Fishel, who played Topanga on the 90s sitcom and Disney Channel reboot "Girl Meets World," shared that after a routine mammogram she was diagnosed with Ductal carcinoma in situ (DCIS) .

"It is very, very, very early. It's technically Stage zero," the 43-year-old shared. "To be specific, just because I like too much information all the time, I was diagnosed with high grade DCIS with microinvasion.

" According to the Mayo Clinic , with DCIS, the cancer cells are confined inside a milk duct in the breast and hasn't spread into the breast tissue. It is a "very early form of breast cancer" that's sometimes called "noninvasive, preinvasive or stage 0 breast cancer," the organization explained. "I'm going to be fine, I'm having surgery to remove it, I'm going to be on some follow-up treatment.

I've had to make a lot of decisions over the last couple of days," Fishel told podcast listeners. The actress admitted she initially thought that if she ever was diagnosed with cancer that she would "suffer in silence." “My first instinct when I was diagnosed was to do that clam-up thing,” she said.

“Then what I realized is, the more people I talk to, the more people had their own experiences, either themse.
