Teddi Mellencamp's doctors have found another "abnormal spot" three months after she underwent surgery in her battle with skin cancer

In a post on Instagram, she shared an update on her surgery scar and shared news from her three-month check-up. She wrote: "What a difference 3 months can make! My scar is healing nicely, and I have the best doctors to thank.

"But in full transparency, also during my three-month checkup, there was one abnormal spot the doctor felt we should biopsy. It's on the other side of my body, so praying it's nothing. But felt it's a great time to remind you to get those skin checks."

Teddi underwent surgery late last year after a new form of treatment to help her immune system fight the cancerous cells didn't work.

Prior to the operation, Teddi explained to fans on Instagram: "Long story short: The immunotherapy treatment did not work on my melanomas. I had a wide excision removal on my most recent melanoma last week to see if it did and sadly it did not.

"I have been presented with a couple new options and I have decided with my doctors that the best next course of action is have surgery on December 26th to remove a larger portion of problematic area.

"I don't like going under and my anxiety is popping off but I have faith all will be ok and that the reason this is happening to me is because I am able to raise awareness. (sic)"

Since the surgery, Teddi has to have a checkup every three months.

Highlighting the importance of booking in skin checks, she added: "After surgery, when god willing my margins are clear, we will continue to monitor my body closely every 3 months. In the meantime, I am so looking forward to spending Christmas with my loved ones and hope this is a reminder to book your skin checks for the new year."
