Study finds cancer risk peaks in older adults but declines after age 80

A new study reveals that cancer risk increases in older adults, peaking in their 60s and 70s, but declines after age 80. Researchers found that older cells produce more of a protein called NUPR1, which limits cell growth and tumor development. The study, conducted on mice and human cells, shows that higher NUPR1 levels create a functional iron deficiency, reducing regeneration and cancer growth. This discovery may lead to new treatments targeting iron metabolism, particularly for older patients. The findings suggest that cancer prevention efforts should focus on younger individuals, as early exposure to carcinogens poses greater risks. The research highlights the need for personalized cancer treatments based on age and other factors.
