The Shocking Progression: From Stage 2 to Stage 4 Melanoma

Teddi Mellencamp’s public health crisis began in 2022 when she was initially diagnosed with Stage II melanoma after a mole was biopsied following a recommendation from her friend and co-star, Kyle Richards. This initial diagnosis marked the beginning of a grueling, years-long medical ordeal that would see her cancer aggressively return and metastasize.

A Timeline of Relentless Surgeries and Diagnosis Updates

The sheer number of procedures Teddi has endured highlights the severity and recurrence of her skin cancer. Her fight is not defined by a single surgery but by a continuous, taxing series of removals and treatments.

• 2022: Initial Diagnosis and Surgeries: Mellencamp was diagnosed with Stage II melanoma. Following this, she underwent her first major surgery, which included the successful removal of several melanomas and a sentinel lymph node biopsy to check for spread. Over the next eight months, she faced 12 separate melanoma removal procedures.
• 2023: Progression to Stage 3: Despite the numerous removals, the cancer progressed to Stage III melanoma.
• April–December 2024: The 15th and 16th Removals: Mellencamp continued to find and have abnormal spots removed, confirming her 15th and 16th melanoma excisions during this period. Her doctors placed her on a strict three-month checkup schedule due to her history of cancer.
• Early 2025: Stage 4 and Brain Metastasis: This was arguably the most shocking development: the cancer had metastasized, or spread, to her brain and lungs, leading to a diagnosis of Stage 4 melanoma. She began suffering from debilitating headaches, which led to the discovery of multiple tumors.
• 2025: Brain Surgery and Ongoing Treatment: She underwent brain surgery to successfully remove four tumors. However, doctors identified an additional five tumors that remained intact. Teddi then began a rigorous course of immunotherapy, a systemic treatment designed to help her own immune system fight the cancer cells.

The Path to Hope: Immunotherapy and Advocacy in December 2025

The Role of Surgery and Immunotherapy

While the initial and recurring treatments involved surgical removal, such as wide local excision—where a larger margin of healthy tissue around the melanoma is removed to ensure all cancer cells are gone—the treatment for her Stage 4 diagnosis shifted. With the cancer spreading to vital organs, surgery became less of a cure and more of a management tool, paving the way for systemic treatments.

The turning point came with immunotherapy. In a major update in May 2025, Mellencamp shared the incredible news that scans showed her tumors had either "significantly shrunk or disappeared." This positive response to the treatment, which she was scheduled to continue for several more weeks, gave her and her followers a massive burst of hope, suggesting that her Stage 4 cancer could be in remission. However, as of a December 2025 update, she continues to share that she is "grateful" but still "struggling" amid her ongoing health battle, underscoring that the fight for remission is a continuous process.

Teddi’s Legacy of Awareness

Mellencamp’s most enduring contribution during this battle is her unwavering commitment to public education. She constantly urges her followers to prioritize annual skin checks, wear SPF, and be vigilant about changes in their moles. Her story has put a spotlight on the fact that melanoma can affect anyone, regardless of their commitment to a healthy lifestyle. She is a living testament to the fact that early detection is the most crucial factor in surviving invasive skin cancer.
