Due to changes in lifestyles and the environment, the incidence of cancer worldwide is increasing. When it comes to cancer, people generally feel that older people will become a high-risk group. However, the reality is that cancer is showing a younger trend. In early December 2021, researchers from multiple centers around the world jointly published a paper in the journal The Lancet calling on young people to increase their awareness of cancer prevention. Let's introduce the main points now.
According to data from a paper published in The Lancet, 1.19 million new cases of cancer and 396,000 deaths from cancer were added to young people aged 15 to 39 around the world in 2019. Cancer has become the fourth leading cause of death among young people worldwide, and the types of cancers that cause young people to die include leukemia, breast cancer, brain and central nervous system cancer, colorectal cancer, and stomach cancer. From the perspective of disease burden, the proportion of these cancers is 12%, 10.6%, 7.4%, 7%, and 6.7%, respectively.
Through data analysis, it is shown that 35 to 39 years old is the age group with the highest proportion of young cancer patients. From the perspective of gender, young women are mainly affected by breast cancer and cervical cancer, and young men are mainly affected by brain and central nervous system cancer and colorectal cancer.
Cancer rejuvenation is the result of a combination of factors, and heredity is an important factor. In 2016, scholars from Denmark, Finland, the United States and other countries jointly conducted a study, and the results showed that at least 22 cancers will be passed on from generation to generation among family members. If siblings develop cancer, the risk of developing the same cancer increases by 33%. However, the genetic risk of different cancers is not the same, and cancers that are susceptible to genetic factors are mainly breast cancer, stomach cancer, colorectal cancer, liver cancer, nasopharyngeal cancer and so on. For example, the risk of breast cancer in mothers and daughters is 2 to 3 times higher than others. For example, 20% to 30% of colorectal cancer patients have a family history. Therefore, if an immediate family member has ever found cancer, it is necessary to strengthen the awareness of prevention and conduct relevant examinations on a regular basis.
In the early stages of cancer, there are usually no obvious symptoms, however, suspicious signals will appear. For example, there are gradually enlarged lumps on the surface of the body, but there is no pain or itch, and the color of the skin surface does not change significantly. Alternatively, the moles on the skin increase rapidly in a short period of time, deepen in color, and appear redness, bleeding, ulcers, surface exudates, hair loss on the surface of the mole, and induration in or around the mole.
Common early warning signs for early cancer are diverse. If the following manifestations are found, they should be checked in time. For example, unexplained loss of appetite, dyspepsia, bloating or discomfort in the upper abdomen, and sustained weight loss. Prolonged fever, anemia, bone pain. Hoarseness, dry cough, blood in sputum. Nasal bleeding, tinnitus, hearing loss, headache. Difficulty swallowing, foreign body sensation in the throat. Abdominal pain, bloody or melena in the stool, alternating diarrhea and constipation, and thinning of the stool. Painless hematuria, sensory disturbances, visual disturbances, loss of smell, vomiting. High menstrual bleeding, increased discharge, contact pain, unexplained amenorrhea, or lactation. The skin of the breast appears wrinkled, the sides vary in size, the nipple is discharged or ruptured, and the nipple is inverted. Young people find that their bodies have these changes that require enough attention.
Relevant research data show that the incidence of many types of cancer in young people continues to increase, and at present, the prevalence of cancer in people aged 15 to 49 years has risen from 0.35% in 1997 to 0.89% in 2017. Scholars believe that the trend of cancer rejuvenation is closely related to modern lifestyles. Among them, breast cancer and colorectal cancer are typical representatives. Frequent staying up late, reduced physical activity, mental stress, poor dietary hygiene habits, etc. are important influencing factors, and these bad life behaviors will lead to a decline in the body's immunity and bring about the risk of cancer. Therefore, to prevent cancer, it is necessary to improve the lifestyle, in addition, it is also necessary to pay attention to regular physical examinations and timely detection of cancer in order to obtain the opportunity for treatment.
