Teddi Mellencamp is ignoring "hard conversations" about the future.

The 44-year-old reality star was diagnosed with stage 4 cancer earlier this year after she was found to have multiple tumours on her brain and lungs, and though she has successfully undergone immunotherapy, which has seen the growths "significantly" shrink, Teddi is "in denial" of her physical condition and doesn't want to speak to her family about the reality of her situation.

Speaking on her Two Ts in a Pod podcast, she said: "I think it's really hard being in a place where, I kind of am in denial of where I am physically. And when other people are not in denial, it's hard.

"My family wants to have like the hard conversations, and I don't... They want to talk about things like the future, or medically, exactly how I'm doing, and I don't want to talk about it."

Her co-host Tamra Judge said: "You don't want to talk about that with anybody."

Her pal quipped: "I don't want to talk about it with you either, for the record Judge revealed that."

Tamra admitted Teddi rarely speaks about her health and she can only gauge what is happening by studying her pal's social media accounts.

She said: "I have to pull it out of you... It's like, I know when you're not feeling well is when you're not posting on Instagram."

The former Real Housewives star revealed last month that her body has been responding well to treatment.

She said on her podcast: "Last time, they had checked solely my brain, and those tumours are shrinking. And then, today I had the scan, where they checked my lungs and they are shrinking and one of them has shrunk so much you can barely even see it."

Despite this, Teddi will have to continue with immunotherapy - which uses a patient's own immune system to fight cancer - for the next two years.

She said: "So every four weeks for the next two years, I have to come in and get that done. And then every three months I get another scan and we check to make sure that everything is where it is."

Asked whether immunotherapy was controlling or curing her cancer, Teddi replied: "It's both.

"It's making sure that it's getting smaller and then let's say that it gets so small that it disappears, it's making sure that it won't form anywhere else in my body.

"I was a little bit worried about having to live on immunotherapy because you know how I am when I get super emotional on certain days. But I think that the fact that this is all moving in a smooth path forward is really good news."
