In 2017, a study published in the Journal of the National Cancer Institute stated that among young people aged 20-50 years, the incidence of rectal cancer is increasing. The institute used SEER registration data from the National Cancer Institute for over 35 years. In addition, the researchers also predict that by 2030, the incidence of colon cancer and rectal cancer will increase by 90% and 124% among adults aged 20-34! The number of people between the ages of 35 and 49 will increase less, 28% and 46% respectively.
過去XNUMX年間で、肥満と肉の消費量の増加は、発症のリスクの増加と関連していますが 結腸直腸癌, reports of newly developing colon and rectal cancer show an average annual decrease of about 2.7%. Smoking is another factor that increases the risk of precancerous polyps and colorectal cancer. Although the proportion of smokers fell from 21% in 2005 to 17% in 2014, according to the Centers for Disease Control and Prevention, it is believed that the majority of colorectal cancer risk reduction is due to improved screening and monitoring of patient risk.
個人にとって、知識が鍵となります。 あなたの健康に注意を払うことが重要です。 直腸がんやその他のがんの家族歴をできるだけ理解することが重要です。 さらに、過度の肥満、赤身の肉の摂取、加工食品、喫煙など、結腸直腸癌のリスクを高める可能性のある要因を最小限に抑える必要があります。
結腸直腸癌のリスクを減らす要因：
■食物繊維：以前の証拠は、食物繊維が結腸直腸癌のリスクを減らすことができることを示しています。このレポートは、90日あたり17グラムの全粒穀物が結腸直腸癌のリスクをXNUMX％減らすことができると報告することによってさらに補足されます。
■全粒穀物：初めて、AICR / WCRF研究は、全粒穀物と結腸直腸癌を独立して関連付けました。 全粒穀物の摂取は、結腸直腸癌のリスクを減らすことができます。
■ Exercise: Exercising can reduce the risk of 大腸癌 (but there is no evidence to reduce the risk of rectal cancer).
■その他：限られた証拠は、魚、ビタミンCを含む食品（オレンジ、イチゴ、ほうれん草など）、マルチビタミン、カルシウム、および乳製品も結腸直腸癌のリスクを減らすことができることを示唆しています。
結腸直腸がんのリスクを高める要因：
■ Large intake (> 500g per week) of red meat and processed meat, including beef, pork, hot dogs, etc .: Previous studies have shown that red meat and processed meat are associated with cancer risk. In 2015, the International Agency for Research on Cancer (IARC), the cancer agency of the World Health Organization (WHO), classified processed meat as a “carcinogenic factor for humans.” In addition, studies of premenopausal women have shown that high intake of red meat can increase the risk of breast cancer. ■ Drink ≥ 2 kinds of alcoholic beverages (30g alcohol) daily, such as wine or beer. ■ Non-starch vegetables / fruits, foods containing heme iron: When the intake is low, the risk of colorectal cancer is high. ■ Other factors such as overweight, obesity, and height can also increase the risk of colorectal cancer. Many methods of preventing colorectal cancer are important for overall health: maintaining a proper weight, exercising properly, limiting red meat and processed meat, increasing the intake of whole grains and dietary fiber, limiting alcohol to a maximum of two glasses per day, and avoiding or stopping smoking. Is it possible to avoid colorectal cancer by achieving the above points? No one can guarantee 100%. However, at least in the process of cancer prevention, it is clear that different “causes” lead to different “fruits”, you know how to choose.
