Medical experts say that 90% of cancer patients are caused by unhealthy life habits, not DNA plays a leading role. Diet, sunlight, smoking, and disease have a “burn-up” effect on cancer, not caused by bad DNA. Dr. Smith of the British Cancer Institute said that healthy lifestyles such as non-smoking, maintaining a healthy weight, eating healthy food and quitting alcohol cannot ensure that people do not suffer from cancer, but can significantly reduce the probability of cancer.
Lesi siphakamiso asimangazi. Ososayensi baye bahlukanisa ukuthi zingaki izehlakalo zomdlavuza ngenxa yendlela abantu abaphila ngayo, nokuthi zingaki izifo zomdlavuza ezingenakugwema. Ukuphikisana kwaqala ngonyaka ongu-1 odlule, lapho izifundo zibika ukuthi amacala amaningi omdlavuza avela ngenxa yamaphutha e-DNA futhi ayenzeka ngezikhathi zomzimba ezingahleliwe kanye nokuhlukaniswa kwamaseli. Lokhu kusho ukuthi iziguli eziningi ezinomdlavuza zibangelwa “ibhadi” kunendlela yokuphila engenampilo.
Njengamanje, ucwaningo lwakamuva lufinyelele esiphethweni esiphambene. UDkt. Yusuf Hannun waseStony Brook University waveza ukuthi nakuba “inhlanhla” inomphumela othile, imikhuba yokuphila engemihle yabantu ingaba nomthelela omubi ezenzweni zomdlavuza. . Le mikhuba yendlela yokuphila engenampilo ihlanganisa: ukudla, ukuphuza, ukubhema, ukukhanya kwelanga, izifo ezithile ezibangelwa amagciwane, ukungcola, nezinye izici ezingakanqunywa.
Umbiko wocwaningo wanyatheliswa kumagazini i-Nature, futhi izakhi zofuzo ezimbi ezitholakala kubazali ziyimbangela yezigameko ezimbalwa zomdlavuza. Imiphumela yalolu cwaningo iqinisekisa ukuthi izigameko eziningi zomdlavuza zibangelwa yimvelo. Uma lezi zinto ezingaba khona zingabonakala, izehlakalo zomdlavuza zingalawuleka.
