The American Association for Cancer Research (AACR) Annual Meeting 2024, held April 5–10, included research that suggests early-onset solid tumor incidence may be greater in younger births due to fast ageing.
At the 2024 Annual Meeting of the American Association for Cancer Research (AACR), the new research was presented. Cancer is an ageing illness, as we all know. Still, it is mostly targeting a younger demographic. Therefore, it’s still very early to tell if we can apply the well-developed idea of biological ageing to the younger generation, according to the study’s senior author, Yin Cao.
Chronological age, or the number of years a person has been alive, is not the same as biological age. According to physiological data, it describes the age of a person’s cells and tissues. For example, a person’s biological age may be younger than their chronological age if they are in good health and physical condition for their age. Likewise, a person’s biological age might be greater if they are in poor physical health.
Contrary to chronological age, biological age may be impacted by a number of variables, including stresses in the environment, nutrition, physical exercise, and mental health. Growing data indicates that younger generations could be ageing faster than expected, most likely as a result of early exposure to certain risk factors and environmental exposures, the speaker continued.
The objective of the study was to ascertain if early cancer development is influenced by accelerated ageing, defined as having a biological age greater than one’s chronological age.
The study used nine blood biomarkers—albumin, alkaline phosphatase, creatinine, C-reactive protein, glucose, mean corpuscular volume, red cell distribution width, white blood cell count, and lymphocyte proportion—to calculate the biological age of nearly 1,50,000 participants whose data were analysed from the UK Biobank database.
According to the biological age trend, those born in 1965 or later were 17% more likely to age more quickly than people born between 1950 and 1954.
We offer a novel viewpoint on the common etiology of early-onset malignancies by investigating the connection between the risk of early-onset cancers and rapid ageing. If confirmed, our results imply that slowing biological ageing may offer a novel approach to cancer prevention. Additionally, screening programmes targeted at younger people exhibiting rapid ageing may aid in the early detection of tumors, according to Tian.
A standard deviation rise in rapid ageing was shown to be associated with an early-life 42% increased risk of lung cancer, a 22% increased risk of gastrointestinal cancer, and a 36% increased risk of uterine cancer. The findings may revolutionize early cancer detection and prevention.
Tian emphasized the possible ramifications of these discoveries, speculating that treatments meant to reduce biological ageing would represent a cutting-edge strategy for cancer prevention.
Because the study only included participants from the United Kingdom, its conclusions might not hold true for individuals from other genetic origins or environments.
