今日双色球开奖结果 www.xnzvqg.com.cn The fear that comes with a cancer diagnosis has roots in the disease’s killer nature. Cancer is the second leading cause of death worldwide, killing more than 9 million people in 2018, according to the World Health Organization, and causing one in six deaths.
In the United States, where the disease is also the second biggest killer, nearly 600,000 people die from it a year, according to the Centers for Disease Control and Prevention.
There is some encouraging news. Cancer death rates declined by 27% from 1991 to 2016, according to the American Cancer Society. This trend is mostly attributed to the decline in smoking rate and better early detection. On the other hand, cancer diagnoses are expected to rise to nearly 23.6 million by 2030, according to the National Cancer Institute. The reason for the increased diagnoses is the fact that people live longer and the risk of developing the disease increases with age, according to Dr. Joseph Lynch, an oncologist from Geisinger. Age is the biggest risk factor for cancer.
While climbing cancer rates are discouraging, there is some good news. “Many types of cancer are increasingly becoming a chronic illness,” Lynch said. In other words, more people are now able to live longer with the disease.
Nationwide in 2016, the latest year for which data is available, 436 new cancer cases were diagnosed for every 100,000 people. 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 most common types of cancer in men and women.
Breast cancer is by far the most commonly diagnosed form of cancer when adjusted to the population of every state in all but six states. In those six states, prostate cancer is the most common. However, breast and prostate cancers are not the deadliest. Lung cancer has the highest mortality rate of all cancers in every state.
The likelihood of being diagnosed with cancer depends on a range of factors that contribute to large variations in cancer incidence among states. Smoking and obesity can significantly increase the risk of a variety of cancers. For example, lung cancer is most closely related to smoking rates. Breast cancer, by contrast, is more associated with obesity than with smoking.
There is some evidence that patients’ survival time is partially linked to insurance status. Regardless of cancer type, privately insured individuals tend to be diagnosed earlier and live longer than cancer patients who are uninsured or covered by Medicaid, according to two studies published in the journal Cancer. People with health insurance are more likely to get screened because they don’t have to pay prohibitively high out-of-pocket prices for tests, and the earlier the disease is caught, the better the chances of survival.
