Baby battles rare cancer from birthmark
27 Mar
Summary
- A 10-month-old girl was diagnosed with cancer stemming from a rare birthmark.
- The birthmark caused painful, bleeding lesions requiring removal and testing.
- Doctors are concerned the cancer may spread, necessitating further treatment.

A 10-month-old girl, Macey-Mai, faces a life-threatening battle with cancer originating from a rare skin condition. She was born with giant congenital melanocytic nevus (GCMN), a condition characterized by large birthmarks, with Macey-Mai's largest covering her entire back. This condition, while typically benign, carries an increased risk of melanoma.
In August 2025, Macey-Mai underwent surgery to remove seven painful, bleeding lesions from her birthmark. These were sent for genetic testing. After months of waiting and monitoring, biopsy results in March 2026 revealed that one of Macey-Mai's lesions was cancerous. Doctors are now concerned about the potential spread of the cancer, indicating that further surgery and ongoing treatment will be necessary for the infant.
Macey-Mai's mother expressed devastation, noting that this diagnosis was unexpected at such a young age, as the condition is typically associated with adult-onset cancer. Despite the challenges, she is focused on celebrating Macey-Mai's upcoming first birthday and providing her daughter with the best possible care.
