The Real Housewives of Beverly Hills star Teddi Mellencamp has been candid about her ongoing battle with skin cancer, using her platform to spread awareness about the importance of regular checkups and sun protection. Sheâs undergone multiple procedures to remove melanomas after being diagnosed and often shares updates with her followers to encourage others to be proactive about their health. While the journey has been difficult, Mellencamp has emphasized resilience and prevention, turning her personal struggle into a reminder that early detection can save lives. Most recently, she said sheâs temporarily stopping immunotherapy treatment. Hereâs why.
Teddi Mellencampâs cancer journey has included multiple surgeries and rounds of immunotherapy since her diagnosis in 2022. After her melanoma metastasized, sheâs been fighting the tumors in her brain and lungs wth the help of her doctors and several treatment plans. The Real Housewives of Beverly Hills star has been open about how challenging the process can be, explaining that immunotherapy often comes with difficult side effects but is crucial in helping her body fight the disease and lower the risk of recurrence. Alongside frequent biopsies and monitoring, these treatments reflect the aggressive approach her doctors have taken to manage her diagnosis.
On Aug. 21, 2025, RadarOnline reported that Mellencamp is pausing her immunotherapy treatments due to the intense side effects sheâs experiencing. Itâs unclear when she will resume them. However, she says, âeverythingâs looking good; everythingâs shrinking.â
Immunotherapy works by strengthening the bodyâs natural defenses so the immune system can better detect and destroy cancer cells. Instead of directly targeting the tumors like chemotherapy does, this treatment trains immune cells to recognize cancer and attack it more aggressively. For conditions such as melanoma, immunotherapy can play a key role in slowing the spread of the disease and lowering the chances of it coming back.
In August 2025, Teddi Mellencamp took to Instagram to ask her followers whether they experienced severe anxiety with immunotherapy treatments related to cancer.
âOK, for those of yaâll whoâve gone through immunotherapy, did you have severe anxiety, just on random days for no apparent reason?â she asked her phone camera while lying in bed. âLike, today, I was able to walk, I did the podcast, and now Iâm just sitting here full of anxiety. Is this common? What are things that you guys have done to help make you feel better? Let me know. Looking for any positive advice.â
In April 2025, Mellencamp admitted that itâs immunotherapy thatâs âkicking her buttâ when she thought itâd be radiation.
âWednesday, I go in and get my next CAT scan, where theyâll find out if these recent tumors are getting smaller, and then I also get my third round of immunotherapy,â she told Extra at the time. âI always thought radiation was the one that was going to kick my butt, but itâs been immunotherapy.â
Teddi Mellencamp has words of advice for those with melanoma.
âIf you have lung cancer, brain cancer, whatever, you still need to continue to get your skin checks, because yesterday, I went to go get a skin check, and I had an abnormal spot,â she said on her Two Ts in a Pod podcast on Aug. 20, 2025. âAnd so they removed it. Theyâre sending it in to get checked.â
Despite this worrying development, she gave âgood news.â
âWhat Iâm telling myself that means itâs OK is itâs in a new spot,â she continued. âAll of my original melanomas were on my back. And this new spot is on my stomach. I just wanted to remind you guys, because I hadnât gone in about six months for a particular skin check.â
