Sugar Bear's brother is missing, and Sugar Bear and Mama June are so worried we're told they've filed a missing persons report.

Rita told People, "I hope this will encourage others to get a second opinion and to trust their instincts if something doesn't 'feel' right."

Taylor Swift's mother is fighting cancer ... but she's only sharing the news with her millions of fans because her mother asked her to do it.

Taylor tweeted an emotional letter to her nearly 56 million followers on Thursday morning -- announcing, "I’m saddened to tell you that my mom has been diagnosed with cancer. I’d like to keep the details of her condition and treatment plans private, but she wanted you to know."

She goes on to say her mom, Andrea Finlay, was diagnosed after Taylor begged her to get a checkup. Taylor says, "She wanted you to know because your parents may be too busy juggling everything they’ve got going on to go to the doctor, and maybe you reminding them to go get checked for cancer could possibly lead to an early diagnosis and an easier battle."

She doesn't specify what kind of cancer it is ... or what the prognosis is for her mother, who is 57.

Swifties obviously feel close to Taylor's family -- she says her mom also wanted fans to know because she knew they'd wonder why she wasn't at as many concerts.

It's hard to watch ... while practicing their routine Sharna kicks him in the face and you hear a tooth hit the floor like it's tap dancing.

Yet Noah -- a total pro -- only has three little words to say about it ... "No Big Deal."

"Mob Wives" star Big Ang received the news she was dreading -- the tumor on her throat is malignant.

Ang’s sister, Janine Detore, tells TMZ the tumor is on Ang's voicebox and her voice is deteriorating as a result. She says doctors determined the lemon-sized growth was cancerous after looking at it with a scope and running blood tests.

Janine says the family is awaiting results of another test to determine if the cancer has spread.

There's no history of cancer in the family, but Janine says they fear Ang's 42 years of smoking might have contributed. She adds ... doctors have ordered Ang to quit smoking immediately.

None of the ordeal has been filmed for "Mob Wives" ... but Janine says it might be addressed on the show at some point. Ang is scheduled to have surgery next week to remove the tumor.

Janine says, "We are hoping for the best and are focusing on getting through the holiday. We love the fans and want to thank them."

"Mob Wives" star Big Ang is currently in the hospital after complaining of pain in her neck ... and doctors have since discovered a tumor in her throat the size of a lemon.

Ang was scheduled to begin shooting for a different reality show, other than "Mob Wives," when she began experiencing the pain.

Ang appeared this past weekend at a reality TV event in New York City where she kept her neck covered up. It's unclear if she was experiencing pain at the time.
