Cancer, aging, and metabolism are closely linked biological processes. With age, the body's ability to repair damaged cells decreases, increasing the likelihood of genetic mutations that can lead to cancer. Aging is linked to metabolic changes like decreased energy efficiency and increased oxidative stress, which can contribute to tumor development and overall cellular damage. Cancer cells take advantage of these altered metabolic pathways to fuel their unchecked growth. As a result, metabolism is an important focus in understanding cancer progression and the aging process. These explanations of connections open the door to innovative treatments aimed at cancer and age-related diseases.
