Teen and young adult cancer survivors face doubled risk of later cancers
Researchers studying cancer survivors over a 34-year period observed that adolescent and young adult survivors of cancer were at a heightened risk of primary neoplasms – new cancers that develop after earlier cancers. The Alberta Adolescent and Young Adult Cancer Survivor Study included all people in Alberta aged 15 to 39 years diagnosed with a first cancer between 1983 and 2017. In this 34-year study period, researchers analysed risks of future cancers, focusing on better understanding of the impact and risks of future disease and death. Of the 24,459 people included with a median follow-up of 7.4 years, 1442 (6%) developed at least one subsequent cancer. Hodgkin lymphoma and breast cancer were the most common types of cancer that saw primary neoplasms develop. The most common types of new cancer that were diagnosed were breast, lung and colorectal, representing 43% of cases. Primary neoplasms are known to occur after earlier cancers, often as a result of treatment “Although people with nearly all types of adolescent and young adult cancer investigated were at an increased risk …
