ガンによる死亡例の半分近くの原因はタバコだそうな

医療・健康

男と女でそれぞれ50％から40％の人がタバコ吸っていたとのこと。人はいつか死ぬわけで、じゃあ喫煙者はどれくらい胃のだろうかと調べてみたら、16％程度。あ、これは以下の調査結果と同じ米国の話ね。

そう。

アメリカ人の16％は喫煙者。そしてアメリカ人の死因の内、ガンが原因なのは23％程度なんだって。

アメリカ人が100人います。そのうち、ガンになる人が23人。そのうち、タバコが原因の人は11人程度。

アメリカ人が100人います。そのうち、タバコを吸っている人は16人です。

The global burden of cancer attributable to risk factors, 2010–19: a systematic analysis for the Global Burden of Disease Study 2019 – The Lancet:

In 2019, the total number of cancer deaths globally attributable to all estimated risk factors was 4·45 million (95% UI 4·01–4·94) for both sexes combined, accounting for 44·4% (41·3–48·4) of all cancer deaths. There were 2·88 million (2·60–3·18) risk-attributable cancer deaths in males and 1·58 million (1·36–1·84) in females, representing 50·6% (47·8–54·1) of all cancer deaths in males and 36·3% (32·5–41·3) in females (appendix pp 191–99). The total number of cancer DALYs globally attributable to all estimated risk factors in 2019 was 105 million (95·0–116) for both sexes combined, which accounted for 42·0% (39·1–45·6) of all cancer DALYs. Males were estimated to have 67·5 million (60·8–75·1) cancer DALYs attributable to risk factors, or 48·0% (45·3–51·5) of all cancer DALYs in males, whereas females were estimated to have 37·6 million (32·8–43·1) cancer DALYs attributable to risk factors, or 34·3% (30·9–38·7) of all cancer DALYs in females.
