Personal life
Nicholls father was Sir Harmar Nicholls, later Lord Harmar-Nicholls, the former Conservative MP for Peterborough and MEP for Greater Manchester South, and subsequently a life peer; she is thus entitled to be addressed as "The Honourable Susan Nicholls". Nicholls has been married to Mark Eden since 1993, Eden also appeared as Alan Bradley on Coronation Street from 1986 until 1989. In 2011, while watching an episode of Coronation Street, Sister Anna Bianconi-Moore, a Senior nurse at the dermatology department at Addenbrooke's Hospital in Cambridge, noticed a mole on Nicholls's shoulder. The nurse contacted the show immediately via e-mail to express her concerns. Nicholls was seen by Dr Zeena Islam – Coronation Street's in-house doctor, who referred her to a skin cancer specialist, where she was diagnosed with malignant melanoma. After the mole was surgically removed, ITV contacted Bianconi-Moore to inform her of the situation, and she was invited to the Coronation Street set to meet Nicholls. Nicholls is said to be very close to Jack P. Shepherd, who plays her on-screen grandson, David Platt. In an interview, Nicholls has said that she treats Shepherd like "her own son".
