Former companion actress Janet Fielding is fighting cancer, it has been revealed.

No more details about her condition are known at the moment but Peter Davison, whose Doctor she appeared opposite as Tegan Jovanka, has won the support of other ex-Doctor actors to launch a charity fund-raising convention - Project MotorMouth - that aims to "not only raise money for a good cause but also keep Janet's spirits up."

Davison, Colin Baker, Sylvester McCoy, Paul McGann, and David Tennant are the first guests announced for the event, which will take place on Saturday 19th January 2013 at the Copthorne Hotel Slough-Windsor. All guests will be appearing subject to work commitments.

The profits from the convention will go to Project MotorHouse, which is seeking to convert a derelict building in Thanet into a mixed-use venue promoting sustainable technology and a place where youngsters can get help with starting their own businesses. Fielding is the project co-ordinator for the organisation as well as its community champion.

She first appeared in Doctor Who in 1981 in Tom Baker's final story, Logopolis, and left the TV series in the 1984 story Resurrection of the Daleks, but made a cameo reappearance two stories later in a regeneration dream sequence for Davison's swansong The Caves of Androzani.

She has also worked as a theatrical agent - a job that saw her representing McGann when he won the role of the Eighth Doctor - and has played the role of Tegan in a number of audio productions for Big Finish.

Doctor Who returns as a specialist subject for the long-running knowledge quiz show Mastermind this coming Friday (8:00pm, BBC2). The questions will be based around the show between 1963 and 1989, while the topics for the other contestants are the geography and history of Arkansas from 1836, football manager Terry Venables, and the story of Moses in the King James Bible.

The show has featured as a specialist subject a number of times in the past, such as in 2004, and notably when the Telegraph's resident Doctor Who reviewer Gavin Fuller became champion during Doctor Who's 30th Anniversary in 1993.

There was also a special Doctor Who-themed version of Mastermind on 19th March 2005 as part of BBC2's Doctor Who Night the weekend before Rose was to herald the triumphant return of the show on television. The questions were set by John Leeson and the winner, Karen Davies, received the trophy from the Doctor himself, Christopher Eccleston. The actor also appeared on Junior Mastermind nearly a year later, where he was interviewed by the young contestant Sam who had chosen Doctor Who's premiere year as his specialist subject on 26th February 2006.

In addition, David Tennant had Doctor Who as his specialist subject on a celebrity edition of Mastermind for Comic Relief on 13th March 2009.

Meanwhile, back in 1988 the New Zealand version of Mastermind featured Doctor Who as the specialist subject from long-term fan Jon Preddle - you can read more about his 'adventure' on the show via the New Zealand Doctor Who Fan Club.

Doctor Who scored higher than most Saturday evening shows, being beaten by the music spectacular Last Night Of The Proms, which scored 90, and Paralympics London 2012, with 88. NCIS on Channel Five also scored highly, albeit with a much lower audience.

With Sunday's overnight rating figures now available, Doctor Who finished 18th for the week, being pushed down by Sunday's X Factor and the closing ceremony of the Paralympic Games. Final figures will be released next week and should see the programme much higher in the final chart once those time-shifting the drama are factored in.
