Cancer before age 50 is rare, but in the United States, I want to know why.
The new government research still offers the most complete picture. Early onset cancerThe biggest increase is that it is in breasts, colon jobs, kidney and uterine cancer. Scientists from the National Cancer Institute have investigated data containing more than 2 million cancers diagnosed with people aged 15 to 49 between 2010 and 2019.
Of the 33 cancer, 14 cancers have increased in at least one young age group. About 63%of the initial cancer was one of the women.
“This kind of pattern generally reflects profound work,” said Dana-Farber Cancer Institute, who is not involved in cancer risks and is not involved in research.
This result was published in the Journal of the American Cancer Research Association on Thursday, Cancer Discovery.
Researchers compared the cancer rate of 2019 with the expected ratio of 2010.
Breast cancer consists of about 4,800 additional examples, which constitutes the largest proportion of excess cancers. There were 2,000 colon rectal cancer compared to what was expected in accordance with the 2010 fare. There were 1,800 kidney cancer and 1,200 additional uterine cancer.
In the case of agents, uterus, and testicular cancer, mortality rates have increased, but mortality rates did not rise in most cancers of young age groups.
The explanation requires more research. The large database used in this study does not include information or access to risk factors. There are many theories and a large meeting is planned to collect experts in this region at the end of this year.
Meredith Shields at the National Cancer Institute said, “Some of these cancer types are known to be related to excessive weight, so one of the main hypotheses is to increase the ratio of obesity.
Changes in the development of cancer detection and changes in the screening guidelines may be after some initial diagnosis.
In the case of breast cancer, the trend of a woman with the oldest child is possible. Pregnancy and breastfeeding are known to reduce risks.
This does not happen overall. The cancer rate of people under 50 years of age is decreasing over 12 cancers and the largest decrease in lungs and prostate cancers.
Tobacco smoking has been decreasing for decades, which will explain the decrease in lung cancer in young adults.
Prostate cancer reduction may be associated with updated guidelines for conducting everyday PSA tests for young men because of concerns about excessive treatment.
