Cancer diagnoses often come as a shock—but when someone is diagnosed at a younger age than expected, the news can feel even more disorienting. For individuals in their 20s or 30s, cancer seems like an improbable occurrence, yet cases of young-onset cancer are on the rise. One often-overlooked contributing factor? Family history and genetic mutations. These "silent risks" may predispose individuals to cancer earlier in life, making awareness and proactive measures essential.
