Continuing a positive trend for the last two decades, cancer death rates declined again last year. According to annual statistics reported from the American Cancer Society, the cancer death rate for men and women combined has fallen 26% from its peak in 1991. This decline translates to nearly 2.4 million deaths averted during this time period.
“Cancer Statistics, 2018,” was published in the American Cancer Society’s journal CA: A Cancer Journal for Clinicians. The information is also available in a companion report, Cancer Facts and Figures 2018, and on a website, the Cancer Statistics Center. Although cancer death rates continue to decline, a total of 1,735,350 new cancer cases and 609,640 deaths from cancer are projected to occur in the US in 2018.
The decline is mostly due to steady reductions in smoking and advances in early detection and treatment. “This new report reiterates where cancer control efforts have worked, particularly the impact of tobacco control,” said Otis W. Brawley, M.D., chief medical officer of the American Cancer Society. “A decline in consumption of cigarettes is credited with being the most important factor in the drop in cancer death rates. Strikingly though, tobacco remains by far the leading cause of cancer deaths today, responsible for nearly 3 in 10 cancer deaths.”
Lung, breast, prostate, and colorectal cancers are leading the way in lower death rates. Lung cancer death rates declined 45% from 1990 to 2015 among men and 19% from 2002 to 2015 among women. Early detection of breast cancer resulted in a 39 percent decline in death rates in women for the same period. Prostate and colorectal cancer experienced a 52 percent reduction between 1970 and 2015, primarily due to increased routine screening.
According to the report, the reduction in death rates is not equal across all ethnic, racial and social economic classes of population. The rates of new cancer occurrence are generally highest among African Americans and lowest for Asian Americans.
Cancer remains the second most common cause of death among children ages 1 to 14 in the U.S. Leukemia accounts for almost a third of all childhood cancers, followed by brain and other nervous system tumors. While child death rates due to cancer have continuously declined since 1975, cancer incidence rates increased in children and adolescents by 0.6% per year for the same period.
The report also reveals that the lifetime probability of being diagnosed with cancer is 39.7% for men and 37.6% for women. The most common cancers to be diagnosed in men are prostate, lung, and colorectal cancers. The most common cancers to be diagnosed in women are breast, lung, and colorectal cancers. Breast cancer accounts for 30% of all new cancer diagnoses in women. Liver cancer incidence continues to increase rapidly in women, but appears to be stabilizing in men.
The good news is particularly rewarding to the professionals at Gettysburg Cancer Center where their understanding of cancer and how to treat it is constantly evolving toward the day when they have a cure. Testing new procedures for identifying and diagnosing certain diseases and conditions, finding ways to prevent certain diseases or conditions before they have a chance to develop, and exploring new methods of supportive care for patients with chronic diseases are at the core of the ongoing clinical trials at the Center.
