Alana “Honey Boo Boo” Thompson confirmed reports that her eldest sister, Anna “Chickadee” Cardwell, was diagnosed with stage 4 cancer.

“& this is what I mean when I say you never truly know what somebody is going through at home. no matter how famous they are,” the former “Here Comes Honey Boo Boo” star, 17, wrote on her Instagram Stories Thursday.

“yes, I’m very famous but normal sh–t happens to me and my family & y’all need to realize that asap.”

Thompson’s post came hours after TMZ broke the news of Cardwell’s diagnosis.

The 28-year-old learned that she had adrenal carcinoma in January after undergoing a series of tests for stomach pain. The cancer was later found in her liver, kidney and lung.

The outlet reported that Cardwell recently underwent her first round of chemotherapy, and further treatment will be decided upon depending on her reaction.

A source added that the mom of two’s relatives are “very hopeful” she will get better and have stepped up to help with her daughters, Kaitlyn, 10, and Kylee, 7, the latter of whom she shares with ex-husband Michael Cardwell.

Two days before the news of her diagnosis, Cardwell returned to Instagram after an eight-month hiatus from the social media platform.

“Well I ain’t posted here in a while,” she captioned a smiling selfie. “Your girl is back sorry for the photo dump that’s going to happen hahah I love y’all and I hope y’all hope y’all are having a good week #imback #2023 #tiktok.”

Fans flooded the comments section of the post with kind words for Cardwell.

“Sending prayers, love, and hugs. I’m sorry you’re going through this. You’re far too young ????,” wrote one supporter, while another added, “I am so sorry to hear about your diagnosis. Peace to you and your family as you go thru treatment.”

A third fan added, “I’m praying for you and your family at this difficult and unimaginable time. My heart goes out to you and sending you love, strength, encouragement and many, many blessings and prayers!!! So sorry you are dealing with this.”
