Letter from Colin Mowl, dated 6 November 2006:
The National Statistician has been asked to reply to your recent parliamentary question asking how many women were diagnosed with ovarian cancer in the Calderdale Primary Care Trust in each of the last 10 years; and at which stage of cancer the diagnosis was made in each case. I am replying in her absence. [98068]
The latest available figures for newly diagnosed cases of cancer (incidence) are for the year 2004. Numbers of cases of ovarian cancer for the years 1995 to 2004 for Calderdale Primary Care Trust (PCT) are given in table 1 .
Stage at diagnosis was introduced in 1993 when the cancer registration minimum data set was established by the Department of Health. There remains much variation in the recording of stage by the regional cancer registries.
Available information for Calderdale Primary Care Trust (PCT) on the numbers of cases of ovarian cancer by stage of diagnosis for the years 1995 to 2004 are given in table 2 .
