As an expert in the field of epidemiology, I can provide you with some insights into the average age for cancer diagnosis. It's important to note that the average age can vary significantly depending on the type of cancer. However, based on the information provided, we can see that a substantial portion of cancer cases are diagnosed in individuals within a specific age range. One-quarter of new cancer cases are diagnosed in people aged 65 to 74. This age group is particularly significant as it represents a considerable percentage of all new cases. When looking at specific types of cancer, the median age at diagnosis varies: - For breast cancer, the median age at diagnosis is 61 years. - For colorectal cancer, it is 68 years. - For lung cancer, the median age is 70 years. - And for prostate cancer, it is 66 years. These figures suggest that while the risk of developing cancer increases with age, there is no single "average age" at which cancer is diagnosed. It's a complex issue influenced by numerous factors, including genetics, lifestyle, and environmental exposures. read more >>

One-quarter of new cancer cases are diagnosed in people aged 65 to 74. A similar pattern is seen for many common cancer types. For example, the median age at diagnosis is 61 years for breast cancer, 68 years for colorectal cancer, 70 years for lung cancer, and 66 years for prostate cancer.read more >>
