new cases of uterine, or endometrial cancer diagnosed each year in the UK
Uterine, or endometrial cancer is the most common gynaecological cancer with around 10,000 new cases diagnosed each year in the UK.
A woman's lifetime risk is 1 in 41.
It is the fourth most common cancer in women after breast (55,000 diagnoses a year), lung (22,000), and bowel (18,000). Its incidence has increased by over 50% since the early 1990s mainly due to increasing obesity rates and an ageing population.
Incidence rates increase from the age of 40 and peak in those aged 70-74.
The main risk factors for uterine cancer are:
Although 5 year net survival in the UK has increased from 32.8% for those diagnosed 1995-9 to 36.4% for those diagnosed from 2005-9, this is still lower than comparable countries in Europe and around the world.

This is multifactorial but the major factors are probably:
| Cancer (years of diagnosis) | 1 year (%) | 5 year (%) | 10 year (%) |
| Ovary (2010-11) | 72.4 | 46.2 | 34.5 |
| Uterine (2010-11) | 90.3 | 79.0 | 77.7 |
| Cervix (2010-11) | 82.8 | 67.4 | 63.0 |
| Vulva and vagina (2009-13) | 82.0 | 64.0 | 53.0 |

A summary of the roles surgery, chemotherapy and radiotherapy play in treating the main gynae cancers:
| Cancer | Surgery | Chemotherapy | Radiotherapy |
| Ovary | For most patients unless very advanced unresectable disease. Complete cytoreduction is the main predictor of survival for those with advanced disease. | All but the most early stage patients or those for palliation will be recommended chemotherapy. Recurrent disease is often sensitive to chemotherapy and novel agents are being used with good effect. | Rarely used |
| Uterine | For most patients and this is usually performed with minimally invasive techniques. | For some high risk patients and for those with recurrent or very advanced disease. | For some high risk patients and some with recurrent disease |
| Cervix | For early stage patients and fertility preserving options may be possible. | For some high risk patients and for those with recurrent or very advanced disease. | For locally advanced disease often with chemotherapy |
| Vulva | For most patients | Rarely | For locally advanced patients |
| Vagina | Sometimes – either early stage or very radical resection | Sometimes in conjunction with radiotherapy | For most patients |
There is concern about women who have had breast cancer using post-menopausal hormone therapy (PHT), or otherwise known as hormone replacement therapy (HRT), because of the known link between oestrogen levels and breast cancer growth.
Previously, PHT has been offered after breast cancer treatment to women suffering from severe symptoms because no harm has been shown. But more recent clinical trials have found that breast cancer survivors taking PHT were much more likely to develop a new or recurrent breast cancer than women who were not taking the drugs. Most doctors now feel that if a woman was previously treated for breast cancer, taking PHT would be unwise.
There is no one test that is particularly good at diagnosing malignant fibroids in the context of specificity and sensitivity but Magnetic Resonance Imaging (MRI), Ultrasound imaging (USS) and Doppler, CA125, trucut biopsy, dilation and curettage (D&C) and lactate dehydrogenase (LDH) are commonly used tests; rather clinical diagnosis with age, with particular attention being given to fibroids that rapidly increase in size, is advised.
