According to new statistics from the Welsh Cancer Intelligence and Surveillance Unit (WCISU) published in its report 'Cancer incidence in Wales, 2001-2016', lung cancer rates appear to be increasing in women but decreasing in men. The rise is pronounced in women from lower socioeconomic groups.
WCISU systematically collects, analyses and disseminates epidemiological parameters of cancer such as incidence, mortality and survival with the goal of improving cancer prevention, health and care services, and outcomes and reducing inequalities.
It is believed that the link between smoking and cancer could be a key factor driving this trend. While rates of smoking in men started dropping in the 1960s and 1970s, the rates in women started increasing.
Breast cancer was the most common malignancy in 2016 followed by prostate cancer, lung cancer and colorectal cancer. The report also indicated that while there is a rise in the number of new cancer cases, a decline in recent years can be seen after adjusting for the population size and age for all malignancies excluding non-melanoma skin cancers.
