Between 1991 and 2015, the cancer mortality rate dropped by 26%. Results related to earlier detection of cancers, better treatments ... and cessation of smoking. However, there are disparities depending on the type of cancer.
2.4 million fewer deaths between 1991 and 2015 in the United States. In this country, source of many therapeutic innovations in recent years, the cancer mortality rate is falling, according to an annual report by the American Cancer Society. Between 2014 and 2015, this rate continued to fall, by 1.7%. According to the researchers, this decrease is due to a better detection of the disease, to the improvement of the treatments but also to the positive effects of stopping the cigarette.
Differences according to the cancers
The decline in the death rate varies according to the type of cancer. For breast cancer, this decrease reached 39% between 1989 and 2015, for the prostate, it is 52% between 1993 and 2015, and for colorectal cancer, 52% between 1970 and 2015.
The lung cancer mortality rate decreased by 45% between 1990 and 2015 for men. For women, the decline was studied between 2002 and 2015 and represents 19% fewer deaths.
Differences between men and women
One in four cancer deaths is due to lung cancer. Prostate for men, breast for women, colorectal cancer and lung cancer in both sexes, are the ones who kill the most. The decline in the cancer mortality rate is, however, higher for men than for women. It has decreased for them by 32% since 1990 against 23% since 1991 for women.
According to this study, there will be in the United States in 2018, 1,735,350 new cases of cancer. 42% of them will be prostate cancer.
A similar trend in France
A report from Public Health France has just drawn up a similar report in our country. Among the main lessons, lung cancer is becoming the leading cause of death for women, with breast cancer being more common. This testifies to the benefit of early detection of breast cancer and its treatment in France. This highlights the obvious failure of public health policies to reduce smoking in France, especially among women.
This study shows that cancer detection efforts have paid off in the United States. "We note, in particular, the impact of the fight against smoking," says Otis W. Brawley, Chief Medical Officer of the American Cancer Society. "Declining cigarette consumption is one of the most important factors in lowering the cancer death rate."
