Abitabiriye amahugurwa bahawe multivitamine ya buri munsi cyangwa umwanya uhwanye nawo.Ibipimo byapimwe byibanze kubushakashatsi ni kanseri yuzuye (ukuyemo kanseri y'uruhu ya nonmelanoma), hamwe na prostate, colorectal, hamwe na kanseri yihariye kurubuga hagati yanyuma.

Abitabiriye PHS II bakurikiranwe mugihe cyimyaka 11.2.Mu gihe cyo kuvura multivitamine, hagaragaye abantu 2,669 banduye kanseri, harimo 1,373 barwaye kanseri ya prostate na 210 barwaye kanseri y'urura runini, aho abagabo bamwe bahura n'ibibazo byinshi.Abagabo 2.757 (18.8 ku ijana) bapfuye mu gihe cyo kubakurikirana, harimo 859 (5.9 ku ijana) bazize kanseri.Isesengura ryamakuru ryerekanye ko abagabo bafata vitamine yagabanutseho 8 ku ijana mu kwandura kanseri.Abagabo bafata vitamine nyinshi bagabanutseho kanseri ya epiteliyale yose.Hafi ya kimwe cya kabiri cya kanseri yibyabaye ni kanseri ya prostate, inyinshi muri zo zikaba zari kare.Abashakashatsi basanze nta ngaruka za vitamine kuri kanseri ya prostate, mu gihe vitamine nyinshi yagabanije cyane kanseri ya kanseri usibye kanseri ya prostate.Nta mibare yagaragaye yagabanutse kuri kanseri yihariye yihariye, harimo kanseri yibara, ibihaha, na kanseri y'uruhago, cyangwa impfu za kanseri.
