The 43-year-old actor - who is best known for playing Topanga Lawrence on the teen sitcom Boy Meets World - recently revealed she had been diagnosed with "a form of breast cancer", and she has taken to social media to thank her fans for their outpouring of support.
"I wanted to do a quick video to say thank you so much from the bottom of my heart and from my entire family for the enormous outpouring of love and support and encouragement you have sent me since I announced my breast cancer diagnosis," Fishel said on Instagram.

Fishel also stressed the importance of having regular health check-ups.
"The only reason we found it that early is because I prioritised myself into making sure I got a mammogram, and I know how important that is now firsthand, and so I wanted to pass along that message," the actor said.
"And I've been hearing from so many of you that you did indeed make your mammogram appointment, or you pressured your mother to make her mammogram appointment, or your best friend to make her mammogram appointment."
Fishel revealed news of her diagnosis this week.
She on the Pod Meets World podcast: "I was recently diagnosed with DCIS, which stands for ductal carcinoma in situ, which is a form of breast cancer.
"It is very, very, very early. It's technically stage zero.
"To be specific, just because I like too much information all the time, I was diagnosed with high-grade DCIS with micro-invasion."
Fishel remains optimistic, insisting she is "going to be fine" and will undergo surgery.
