CA Cancer J Clin: Revealing the cruel truth that cancer is getting younger! The number of cancer cases among young people has been increasing in the last 10 years.

In recent years, the global incidence of cancer has been increasing for complex reasons, reflecting both the ageing and growth of the population and changes in the prevalence and distribution of major risk factors for cancer.
, the incidence of cancer increases with age, and the higher the incidence of cancer in countries with longer life expectancy.
with socio-economic development and the ageing of the population, cancer as the leading cause of death is becoming more and more prominent.
cancer patients tend to be overlooked relative to older people, however, research data in recent years suggest that cancer is on the rise.
growing evidence that tumors in young cancer patients differ molecularly from those in children and older cancer patients, meaning they may differ in the cause of cancer and effective treatments.
young cancer patients should have had more time, and once they had cancer, they had a greater impact than older patients, and young people, who were not high-risk cancers, were vulnerable to neglect delays in diagnosis and treatment.
September 17, 2020, CA (IF-292), the highest academic journal for global influence factors, published a research paper from the American Cancer Society and others entitled: Cancer statistics for adolescents and young adults, 2020 (Adolescent Cancer Statistics 2020).
study looked at a group of 15-39-year-olds, who were divided into three groups: 15-19, 20-29, and 30-39.
the study, which counts the last 10 years (2007-2016), the incidence of cancer among young people of all ages (15-39 years old) has been rising, with about 89,500 new cancer cases and 9,270 new cancer deaths expected among 15-39 year olds by 2020.
The types of cancer vary widely among young people of all ages, with the highest incidence of lymphoma among adolescents aged 15-19, while thyroid, testicular and melanoma rates are highest in the 20-29 age group, with female breast, thyroid and melanoma among the top three.
it is worth noting that the top three incidences in each age group have thyroid cancer.
the table above, with the exception of leukemia, Hodge lymphoma and other children with high incidence of cancer, the incidence of almost all cancers increased rapidly.
the gender difference in cancer incidence is significantly in the 15-19 age group, the overall incidence of cancer is similar for men and women, with 23 and 24 cases for men and 24 cases per 100,000 population, respectively.
the age group 20-29, the incidence of cancer is 42 and 55 cases per 100,000 population, respectively, and the incidence of cancer among women is 30 per cent higher than that of men.
the incidence of thyroid cancer in women is five times higher than in men (15 per 100,000 vs 3 per 100,000).
In the 30-39 age group, the incidence of cancer in men and women per 100,000 population is 84 and 161, respectively, and the incidence of cancer in women is almost twice as high as in men, mainly due to the high incidence of breast, thyroid and skin melanoma in this age group, especially in female breast cancer, especially in the 30-39 age group, the incidence of breast cancer in women is rising rapidly, more than 20-29 years of age, the incidence of more than 60%.
it is worth noting that women rarely smoke, but women under the age of 30 have a higher incidence of lung cancer than men, the reasons for which need further study.
In recent decades, cancer morbidity has been rising, and the study counts cancer morbidity and mortality rates for all ages since 1975, and it is clear that cancer mortality rates for all ages have been declining almost all the time, naturally as a result of economic development and advances in health care.
the incidence of cancer is more complex, and overall, the incidence of cancer has increased among young people of all ages since 1975.
In the late 1980s, the incidence of cancer suddenly increased rapidly among men aged 20-29 and 30-39, and then recovered in the early 1990s, in line with the outbreak of AIDS, due to an increase in the number of people living with Capoci sarcoma as a result of the outbreak.
, the incidence of thyroid cancer increased significantly, and it increased significantly at all ages, especially among women of all ages.
one of the main reasons for this is that advances in imaging have led to higher levels of testing.
Cancer mortality rates are declining In addition to the increase in cancer mortality among men aged 20-39 as a result of the AIDS epidemic in the mid-1980s to the mid-1990s, the five-year survival of cancer in the overall youth population has been increasing since the 1970s, and mortality rates have been declining, with cancer mortality rates falling by an average of 1 per cent per year over the past decade.
2009-2015 statistics, the five-year survival rate for cancer patients aged 15-39 is 83%-86%, well above the 66% of cancer patients over the age of 40.
15-29 years of age have higher cancer mortality rates than women, due to differences in the types of cancers among men and women, as well as high rates of cancer mortality among men such as melanoma.
30-39 years of age, female cancer mortality increases due to the high incidence of breast cancer in women.
For young people of all ages aged 15-39, leukemia and brain tumours are the leading causes of cancer death for all genders and age groups, with the exception of women aged 30-39, who die mainly from breast and cervical cancer.
Although this study is aimed at the U.S. population, the overall situation in China is similar, according to the 2018 statistics of the National Cancer Center of China, the incidence of cancer in China continues to rise, but also show a trend of younger cancer.
overall, the incidence of cancer among young people is still much lower than among older people, but the increasing incidence of cancer among young people in recent years is a reminder that we must pay attention to this problem.
Addition, the pressures of modern society on young people's lives, staying up late, unhealthy eating, lack of exercise and other bad habits, as well as environmental pollution, will accelerate the unhealthy state of young people, and even induce cancer.
, despite rapid advances in scientific understanding of cancer in young groups in recent years, there is still little research on the causes, basic biology, treatment and improved survival.
, in addition to hope for scientific progress, more important is to rely on their own, develop good habits, more exercise, the body is the capital of the revolution.
