Cancer is rare before the age of 50, but is increasing, in the United States and researchers want to know why.
A new official study provides the most complete image of primary-incense cancer, it finds that the largest growth is in breast, colorectal, kidney and uterine cancer. Scientists at the National Cancer Institute watched data that include more than 2 million cancers diagnosed between 5 and 6 years of age between 20 and 20 years.
In 33 cancer types, 14 cancer rates were raised in at least one younger age. About 5% of the primary-early cancer was among women.
“These types of patterns usually reflect that something deep can happen,” Team Rebeck of the Dana-Farmer Cancer Institute says those who study the risk of cancer and were not involved in research. “We need research funds that will help us understand.”
A journal from the American Association for Cancer Research was published on Thursday to discover cancer.
Researchers have compared the cancer rate in 2019 with what to expect on the basis of 2010.
Breast cancer has made the largest part of excess cancer with an additional case of about 4,800. There were more than 2,000 colorectal cancer compared to what would be expected on the basis of the rate of 20. There were more than 1,800 kidney cancer and 1,200 additional uterine cancer.
Assurely, the mortality rate for most cancer of young adults was not increasing, although the growing mortality rate was seen for colorectal, uterus and testicular cancer.
The explanation will take further research. Large databases used for study do not include information related to risk factors or access to care. The theories are abundant and a large meeting is planned to combine experts in the region by the end of this year.
Meredith Shillus, the leading author of the National Cancer Institute, says, “A number of cancer is known to be involved in excess body weight and therefore raising the rate of obesity among the top estimates,” Lead author of the National Cancer Institute, Meredith Shill, says.
The progress of cancer detection and the changes in screening guidelines may be behind the diagnosis of some primary disease.
For breast cancer, the tendency to be the first child at an older age is a possible explanation. Known to reduce the risk of pregnancy and breastfeeding.
This is not happening across the board. Cancer rates are falling for more than a dozen cancer among people under the age of 50, the biggest decrease in lung and prostate cancer.
Cigarette smoking has been declining for decades, which are probably decreasing lung cancer in young people.
The decrease in prostate cancer is probably due to the update guidelines to discourage routine PSA tests in young men because of anxiety about overraitments.
