The number of cancer deaths has fallen by 27 percent in 25 years, but not all see the same benefits



It seems we are finally making significant progress in the prevention of cancer deaths . According to a new report by the American Cancer Society, the mortality rate for the disease fell by 27 percent between 1991 and 2016. This means about 2.6 million fewer deaths during this period, mainly due to a reduction in deaths from smoke-related cancers and breast cancer. However, the report also uncovered the coverage gaps we still have to address.

For the report published on Tuesday CA: A Cancer Journal for Clinicians the researchers analyzed the frequency, mortality and survival rate of cancer data from the National Center for Health Statistics, the Monitoring, Epidemiology and Final Regulations Program, the National Cancer Register and the North American Association of Cancer Registries.

These data showed that the nationwide cancer mortality rate was affected. In 1991, a peak of 215.1 deaths per 100,000 population was reached, falling in 2016 by 1.5 percent to 156 per 100,000 inhabitants. Nevertheless, the report assumes that in 2019, 1,762,450 new cancer cases and 606,880 cancer deaths will be diagnosed in the US. 19659006] Although the number of deaths from lung cancer and breast cancer has declined significantly in recent decades, the deaths associated with other cancers did not show the same pattern.

The mortality rate for [1 9459004] lung cancer decreased by 48 percent in men and 23 percent in women between 2002 and 2016 from 1990 to 2016. In addition, the rate for female breast cancer fell by 40 percent from 1989 to 2016, the number of prostate cancer cases from 1993 to 2016 by 51 percent and the colorectal cancer mortality from 1970 to 2016 by 53 percent.

It was not all good news. Between 2012 and 2016, the incidence of liver cancer increased by 0.3 percent per annum for both men (1.2 percent) and women (2.6 percent), per year for pancreatic cancer, and 2.1 percent per year for endometrial carcinomas. Brain and other nervous system, soft tissue and oropharyngeal carcinoma-related cancers associated with human papillomavirus (19459022) (HPV) also increased.

According to experts, the decrease in total cancer mortality is likely due to a combination of several factors.

One major factor is the decline in cigarette smoking in the US, says Matthew Schabath, Ph.D., cancer epidemiologist at the Moffitt Cancer Center, opposed to SELF. "Over time, with fewer people smoking, the number of cancers declining with tobacco use," he says. These include lung cancer as well as leukemia, gastric cancer and bladder cancer, among others Alyssa Rieber, MD, chairman of the Department of General Oncology at the Anderson Anderson Center of Anderson, University of Texas, reports to SELF.

The Decline May Be Manifested By People who are pursuing a healthier lifestyle, including eating, exercising regularly, and reducing the alcohol content they have, J. Leonard Lichtenfeld, Interim Chief Medical Officer of the American Cancer Society, opposite SELF.

And finally, there has been advances in early detection techniques for various cancers that are used more frequently, Dr. Lichtenfeld. In particular, Breast Cancer and Screening of Cervical Cancer have dramatically changed the techniques and guidelines in recent decades.

Although the number of cancer deaths in the US has declined overall, they still have significant racial and economic gaps in mortality rates.

The racial gap in cancer mortality is waning – the death rate for black Americans was 33 percent higher in the mid-1990s than for white Americans, and the gap is now at 14 percent – but still exists. Schabath describes the reduction of the race gap as "encouraging" and says that this is probably due to years of concerted efforts at local, state and national level to reduce differences in race and ethnic cancers. He adds, "More work is needed."

There is also a growing gap in mortality rates due to socioeconomic status. Between 2012 and 2016, the overall cancer mortality rate for people living in the poorest districts of the US was about 20 percent higher than for those living in the most affluent districts. For some types of cancer, the gap was even greater: for example, the cervical cancer mortality rate in the poorest areas is twice as high as in the most affluent areas. However, there was little difference in mortality rates between socioeconomic groups for cancers, which are generally more difficult to study and treat (eg, pancreatic cancer and ovarian cancer).

"We can do better," says Dr. Lichtenfeld. "Unfortunately, not everyone has access to care." For example, if someone has concerns about putting food on the table, it will obviously be hard to justify taking the time to do a cancer screening. "And if they're diagnosed again, [they] may not have insurance or adequate insurance, which will delay their care. "

Overall, however, the experts are still feeling positive with the new numbers." This is fantastic news, "says Dr. Rieber," It's great for people to know that people can live longer if we have cancer However, doctors and researchers are under pressure to extend high-quality care to all: "We should continue to put pressure on us to ensure everyone has access and good treatment options."
