Most common cancers




In Northern Ireland, non-melanoma skin cancer (NMSC) made up 26.4 per cent of all male and 24.3 per cent of all female cancers between 1993 and 2004. Excluding this cancer type, the most commonly diagnosed male cancers, in descending order, were prostrate (12.9 per cent), lung(12.8 per cent) and colorectal (11.3 per cent). In females, they were breast (20.8 per cent), colorectal (10.2 per cent) and lung (7.6 per cent).Cancer deathsDuring the same time period, the same cancers (with the exception of NMSC), were the most common causes of cancer death but in a different order. Amongst males, lung cancer was the most common cause of cancer death, while among females breast cancer was the most common cause.During 1993 to 2004 there were on average 4,318 male and 4,414 female cases of cancer diagnosed each year in Northern Ireland. Excluding NMSC, there were 1,863 male and 1,746 female deaths from cancer each year.Improvements in relative survivalDuring the 1993 to 2003 period covered by the report, one year relative survival improved for all patients with non-Hodgkins lymphoma, colorectal or lung cancer, for females with oral or breast cancer and for males with prostate cancer.Five year relative survival also improved between 1993 and 2000 for males with oesophageal or prostate cancer and females with colorectal or breast cancer.Cancer trendsAmongst males, trends highlighted in the report show that incidences and mortality of oral, stomach and lung cancer have decreased, while incidence of prostate cancer has risen due to increased use of prostate specific antigen or PSA testing. The need to take care in the sun and particularly to avoid sunburn in childhood and sunbeds is also highlighted, as figures show an increase in incidences and mortality from melanoma in males.In the Northern Ireland female population, deaths from melanoma, leukaemia, colorectal and breast cancers have fallen, as have rates of stomach, cervical and colorectal cancer. The report also shows though, that among females, incidence rates of melanoma, breast, uterus and ovarian cancer have increased.
