Teddi Mellencamp has revealed that her stage 4 cancer is "gone"

Teddi told the iHeartRadio podcast Two T's in a Pod: "Just to give a little life update to you guys, I had my immunotherapy yesterday and they did my scans and at this point there is no detectable cancer.

"I still need to be on immunotherapy for another year and I'm not considered in remission or anything like that."

The Real Housewives of Beverly Hills star explained that she was "numb" with shock after being told of the positive development in her cancer battle.

Mellencamp said: "When they told me, I was in such shock, I was numb. So I'm still going to be having days when I'm feeling sick and stuff because I am still in immunotherapy, so I'm still fighting because you have to be.

"The way they (doctors) said it works, it's like one year, then two years, then at three years you're allowed to be considered... in remission. So, but that was huge news yesterday."

She added: "All the tumours continued to shrink and everything. It's been good. It's a good day."

Teddi - who has children Slate, 12, Cruz, 11, and Dove, five, from her marriage to estranged husband Edwin Arroyave - explained that it is just her eldest who has been able to understand her health update so far.

She said: "It's just Slate that really understands. People think just because the cancer's gone, that I can't still get sick or whatever, but I'm still in treatment."

Teddi had taken to Instagram last month to ask for her followers to send positive messages as she was "struggling" with her illness.

She wrote: "Mondays, am I right?

"Emotions high. Love to everyone out there. If I haven't responded to your text, I love you. I am just struggling.

"How are y'all doing? Would love to hear one of your positives from today.

"Mine is: I feel very grateful for the people in my life. (sic)"
