The study found that overall, early-onset cancers increased over that decade, by an average of 0.28% each year.
There were 34,233 early-onset cancer cases in women in 2010 and 35,721 in 2019, an increase of 4.35%, the study says.
The rate of cancer diagnosis increased in adults in their 30s over the decade but remained stable in other under-50 age groups, the study found.
Cancers with the highest numbers of early-onset cases diagnosed in 2019 were breast (12,649 cases), thyroid (5,869) and colorectal cancers (4,097).
Previous research has shown a rise in cancers of the digestive system, particularly colorectal cancers, among adults younger than 55 since the 1990s.
