Teddi Mellencamp Gives New Health Update After Calling Out Her Doctors for Missing Her Melanoma Spreading

   

Teddi Mellencamp is providing a health update on her stage 4 cancer diagnosis.

Teddi Mellencamp Arroyave arrives at the Alliance for Women in Media Foundation's 50th annual Gracie Awards Gala at Beverly Wilshire, A Four Seasons Hotel on May 20, 2025 in Beverly Hills, California.

In the Wednesday, July 23 episode of her podcast Two Ts in a Pod with Teddi Mellencamp and Tamra Judge, Mellencamp offered further details on her ongoing treatment.

"Essentially, I haven't been feeling good for about a month, which was kind of shocking to me, and I think, mentally did a lot to me," she began.

The Real Housewives of Beverly Hills alum, 44, elaborated that she could barely open her eyes or "keep her words straight." She then revealed that she would be pausing immunotherapy treatment due to these side effects, as her team of doctors performed scans that showed her tumors were shrinking, with some "barely visible."

"We're going to take a little break on the immunotherapy to get my body back feeling stronger," she said.

Mellencamp also revealed that while her divorce filing from Edwin Arroyave stands, the proceedings remain on hold as she undergoes treatment.  

"I've never in my adult life been in a situation where I'm like, 'Gosh, I can't do this right now.' I can't stay up that extra hour and put my kid to bed tonight, I can't go to my daughter's horse show, or oh my gosh, I'm going to have to miss Cruz's practice. I've never once felt that way until recently, and it's heartbreaking," Mellencamp said of how her cancer journey has impacted her relationship with her three children, Slate, 12, Cruz, 10, and Dove, 5.

Mellencamp explained that recapping episodes of RHOBH has been difficult for her as she undergoes treatment for her brain tumor, but that she is working to "shield" herself from memory loss.

She then recounted a vulnerable moment before her July 17 interview with Glamour alongside fellow RHOBH star Kyle Richards.

"That day, everybody was like, 'Oh my gosh, Teddy, you look so beautiful, you look so strong, you look like you're on top of the world,' " Mellencamp said. "And I remember that day lying up in a ball before going calling Kyle and Jen and going, 'If one of you guys don't pick me up, I can't even be in a car service. I'm too embarrassed, like I'm not doing well. I can't do this today."

The health update on Two Ts in a Pod comes after Mellencamp called out her doctors for not performing scans on her earlier diagnosis of stage one melanoma when a patch of the cancer was discovered on her shoulder.

“I never really thought about it because I was like, ‘I go to a doctor every three months. Why wouldn’t they get me checked?’ My highest melanoma on my shoulder was stage one. When I finally followed up on it, they were like, ‘We didn’t do the scans, because you didn't have anything above a stage one on your body.’ But look what happened," she told Glamour.

Mellencamp revealed in April that her disease progressed to stage 4, having metastasized to her brain and lungs. She has undergone surgery, radiation, and, until recently, immunotherapy, to treat the tumors.
