Cancer of the uterus is classified by ICD-10 into three sites—cancer of the cervix uteri (cervical cancer; see Chapter 20), cancer of the corpus uteri (uterine cancer; discussed in this chapter), and cancer of the uterus, part unspecified. “Part unspecified” cases make up less than 5% of all cancers of the uterus and are not considered here.
Cancer of the corpus uteri (uterine cancer) was the sixth most common cancer in women in Ireland, accounting for 3.9% of all malignant neoplasms, excluding non-melanoma skin cancer, in women (Table 19.1). The average number of new cases diagnosed each year was 403. During 1995-2007, the number of new cases diagnosed per year increased by 7% in NI and 3% in RoI.
The risk of developing uterine cancer up to the age of 74 was 1 in 77 and was slightly higher in NI than in RoI. At the end of 2008, 1,756 women aged under 65, and 2,419 aged 65 and over, were alive up to 15 years after diagnosis.

| Ireland | RoI | NI |
% of all new cancer cases | 2.9% | 2.7% | 3.2% |
% of all new cancer cases excluding non-melanoma skin cancer | 3.9% | 3.7% | 4.2% |
average number of new cases per year | 403 | 258 | 145 |
cumulative risk to age 74 | 1.3% | 1.2% | 1.4% |
15-year prevalence (1994-2008) | 4175 | 2623 | 1552 |
Almost 80% of cases of uterine cancer were diagnosed between 50 and 79 years of age, with 27% presenting between 50 and 59 years, 30% between 60 and 69 years and 22% between 70 and 79 years (Figure 19.1). Only 11% of cases were diagnosed in women aged less than 50, with a further 10% diagnosed in those aged 80 and older.
