Cancer patients are living longer today due to early detection and better treatment options. The number of cancer diagnoses, however, is increasing and is expected to rise to nearly 23.6 million by 2030, according to the National Cancer Institute. Part of the reason is that the population is aging, and age is one of the biggest risk factors for cancer.

The sooner a cancer is diagnosed the better the odds of beating it. The problem is that many cancers, regardless of where they originate, often have non-specific symptoms, such as fatigue, that people ignore.

In the U.S., approximately 40 out of 100 men and 38 out of 100 women will develop some form of cancer during their lifetime. These are the states with the highest and lowest cancer rates.
