Teddi Mellencamp says her cancer is now Stage 4 after metastasizing to the lungs and brain

Mellencamp thanked her followers in a video for their "many kind messages" after being originally diagnosed and treated for skin cancer in 2022.

“I just want to say thank you guys so much.  So many messages about how strong I am.  And I gotta tell you, some days I feel really really strong and some days I feel really really sad and alone,” Mellencamp said. “And I think that’s a normal part of what any of us are going through, and that’s okay. Stage 4 cancer can be scary.”

Last month, she posted on Instagram about her therapy.

“Update from my scans today: I have multiple tumors in my brain that weren’t able to be removed via surgery. I also have 2 tumors in my lung,” she wrote at the time. “These are all metastases of my melanoma.”

Her estranged husband, Edwin Arroyave, has returned to their house to assist care for their children, she added.

"And I’m really lucky that Edwin, who I was in the middle of a divorce from, we put everything on hold. ... That’s made things a lot easier," she said.
