The Duchess of York has spoken of her “shock” at being diagnosed with malignant melanoma, but says she is in “good spirits”.
In an Instagram post, she said she was “grateful for the many messages of love and support”.
The melanoma was discovered following the removal of a cancerous mole during treatment for breast cancer.
The duchess, Sarah Ferguson, had several moles removed and analysed while having reconstructive surgery.
The duchess is the third royal to announce a medical procedure this week.
