Teddi Mellencamp Reveals 3 More Tumors Were Found in Her Brain, and 2 More in Her Lungs: ‘I Will Beat These Tumors’

Teddi Mellencamp revealed that more tumors have been found in her brain and lungs.

On Thursday, March 6, the Real Housewives of Beverly Hills alum, 43, posted a health update to her Instagram profile, and then added the update to her Instagram Stories minutes later.

“I have 3 more tumors in my brain and 2 tumors on my lungs. These are all a direct result of my melanoma,” she began the Instagram caption. Over the past two years, she had 17 different spots of melanoma removed.

“The doctors are hopeful that these additional mutations will be removed via immunotherapy. That begins Tuesday at 11AM,” she continued. “I am feeling positive and excited— that I will beat these tumors.”

She also shared she got a blonde wig, confirming that she does “like the short hair, just not the bald spots.”

“Now, as @bravoandy would say: with all due… f*** off, cancer!”

On Tuesday, Feb. 12, Mellencamp said she was “dealing with severe and debilitating headaches” for several weeks. The “unbearable” pain then “required hospitalization.” Once at the hospital on Monday, Feb. 11, she received a CT scan and MRI, and “doctors found multiple tumors on my brain, which they believe have been growing for at least 6 months.”

Four of the tumors were surgically removed on Feb. 12. “The remaining smaller tumors will be dealt with via radiation at a later date,” she wrote at the time.

Nearly two weeks later, on Wednesday, Feb. 26, she shared her first post-surgery update. “I am so grateful for the incredible surgeons, doctor, and nurses who made my surgery a success and my recovery process comfortable,” she wrote. “This fight is not over, but that round has been won.”

She also added a video on her Instagram Stories of her getting surgical staples removed from the back of her head.

Two days later, she said she was “ready for radiation,” in a Friday, Feb. 28 Instagram post.

On Tuesday, March 3, she revealed she was returning home from the hospital after being in the facility’s care for 16 days. “Thank you to all my loves and life savers for getting me to this day,” she captioned her Instagram Stories. 

The podcast host also confessed that it is “obviously very emotional watching your body change with so much medication from the brain tumors.” 

“But just trying to remember how grateful I am that I can move my body again,” she said while tearing up. “One day at a time and I’ll get back to where I wanna be, feeling my best.”

Mellencamp’s latest diagnosis comes amid her years-long battle with skin cancer and the removal of over 17 different spots of melanoma — most recently in December 2024.

According to the National Institute of Health, up to 60% of patients with advanced melanoma develop brain metastases during the course of their disease, and “the presence of brain metastases significantly worsens a patient’s prognosis.” This occurs when cancer cells migrate through the blood-brain barrier.
