Cancer Incidence in Wales, 2006-2010
The Welsh Cancer Intelligence and Surveillance Unit have published cancer incidence statistics for the diagnosis period 2006-2010 (24th January 2012).
The main findings from this report are as follows:
- There has been a slight increase (1.1%) in the total number of malignancies excluding non melanoma skin cancer (NMSC) in Wales in 2010 compared to 2009 for males, a 0.8% decrease on 2008 and a 2.8% increase on 2006. There has been an increase for females in 2010 compared with 2009 of 52 registrations (or 0.6%) and an increase of 3.6% compared with 2006.
- The increases seen in both sexes between 2009 and 2010 cannot be attributed to one individual cancer site as there have been increases for many cancer types as well as decreases for other cancer types.
- For the most common cancer for both sexes: the number of cases for prostate cancer in 2010 has slightly increased compared to 2009 and slightly decreased from 2008 – a similar pattern is seen in breast cancer, the most common cancer in females.
- Cancers which show increases in the number of cases in 2010 compared to previous years are male colorectal cancer, male malignant melanoma of the skin, cancer of the corpus uteri and pancreatic cancer (both sexes).
- Cancers which show decreases in the number of cases in 2010 compared to previous years are male lung cancer, stomach cancer (both sexes) and female colorectal cancer and cervical cancer. The numbers for cervical cancer show a large decrease. WCISU have investigated this decrease with Screening services and believe this decrease to be true.
- Overall, the EASR has slightly decreased for males and slightly increased for females in 2010 compared to 2009. However, the highest EASR in females was seen in 2008 whereas the highest EASR in males was seen in 2007.
- The report also shows cancer incidence statistics for the two cancer networks in Wales for the most common cancers. For all malignancies excluding non melanoma skin cancer, the highest EASR in 2010 was found in North Wales cancer network, 3.8% higher than in South Wales cancer network for males. However, for females, the highest EASR in 2010 was found in South Wales cancer network, 1.0% higher than in North Wales cancer network.
- New bladder cancer coding rules were implemented for those bladder cancers diagnosed from 2007 onwards according to the United Kingdom Association of Cancer Registries (UKACR). Hence, figures for bladder cancer diagnosed in 2006 will be higher than those diagnosed from 2007 onwards.
