‘She gave one hell of a fight for 10 months she passed away with her family around her like she won’t and we will will be updating y’all with more information as we get it today [sic],’ Shannon continued.

‘We love y’all and continued prayers and thoughts for our family [during] this difficult time,’ she added.

Anna was diagnosed with stage four adrenal cancer in January after complaining of stomach pain. 

The Mayo Clinic reports adrenal carcinoma is a rare cancer that affects the adrenal glands in the kidneys. The adrenal glands produce hormones which deliver instructions to virtually every organ and tissue in the body.

The mother of two girls, Kaitlyn, 11, and Kylee, eight, underwent chemotherapy and immunotherapy in an attempt to beat her cancer. 

Over the summer, the From Not to Hot star revealed that Anna’s cancer was terminal. 

‘We know it’s terminal. She’s stage 4. She’s not gonna go into remission,’ she wrote, adding: ‘We’ve all accepted that, so I just tell people one day at a time ’cause you never know.’

The average age of patients with adrenal cancer is 46, but it can occur in people of any age, even in children, according to the American Cancer Society.

Adrenocortical carcinomas start in the outer layer of the adrenal glands, which are next to the kidneys. The adrenal glands are small glands producing hormones.

Most growths that form in the adrenal glands are noncancerous.
