Brandon Blackstock had melanoma, which is a form of skin cancer. He battled this serious and aggressive type of cancer privately for more than three years before passing away peacefully at his home in Butte, Montana, on August 7, 2025, at the age of 48. Melanoma arises from melanocytes, the pigment- producing cells in the skin, and is considered one of the deadliest forms of skin cancer due to its potential to rapidly spread to other organs. The cause of his death was confirmed by the Silver Bow County Coroner and his death certificate listed malignant melanoma as the cause of death, with the manner of death being natural causes. This type of cancer is often linked to exposure to ultraviolet rays from the sun or tanning beds and requires coordinated care for treatment depending on the stage of the disease. Blackstock's courageous battle with melanoma was kept largely private, and he was surrounded by his family at the time of his passing. In summary, Brandon Blackstock died from malignant melanoma skin cancer after a three-year battle with the disease.
