Cancer is usually more frequent in older people due to biological, environmental and lifestyle factors. Aging increases cell divisions, which leads to the accumulation of mutations and a greater risk of acquiring the disease. However, studies revealed a worldwide trend: Cancer is increasingly diagnosed with more young adults, often without a family history of the disease.
According to a recent study published in the magazine BMJ Oncologythe incidence of early appearance cancer among adults under 50 years old worldwide increased 79 percent between 1990 and 2019, and diseases related to the disease in the same group increased by 28 percent. The same research analyzed 29 types of cancer in 204 countries. Specifically, nasopharyngeal, stomach and colorectal have increased among young adults, according to the same article.
Even, in a report published in The Lancet Public Health He revealed that rates of 17 types of cancer have constantly increased throughout generations in the United States, particularly between generation X and millennials (born between 1965 and 1996). The American Cancer Society (ACS) He pointed out that breast cancer incidence rates among white women under 50 increased annual 1.4%, compared to 0.7% among those over 50 between 2012 and 2021.
Until now, dietary factors, together with alcohol and tobacco consumption, are among the alleged culprits, according to BMJ Oncology and The Lancet reports. The World Health Organization (WHO), Obesity is closely related to the increased risk of cancer due to inflammation and hormonal deregulation.
On the other hand, some argue that constant exposure to the artificial light of devices or lamppings can alter the biological clock and increase the risk of breast, colon, ovarian and prostate cancer. While other investigations have suggested that prolonged exposure to light at night, can also reduce melatonin levels, favoring the appearance of cancer.
“Researchers argue that ultraprocessed food additives, such as emulgent and dyes, can cause intestinal inflammation and DNA damage. Intestinal alterations are related not only to colorectal cancer, but also with breast and blood, ”according to the American Association for Cancer Research in a report republicated by the BBC Mundo.
