Ndipo posachedwapa, asayansi asindikiza zotsatira za kafukufuku wina wa "khofi". Zikuoneka kuti ngati munthu amamwa makapu awiri a khofi patsiku, chiopsezo chokhala ndi khansa ya chiwindi chimachepetsedwa ndi 46 peresenti - pafupifupi theka! Koma padziko lonse m’chaka chathachi, anthu oposa miliyoni imodzi amwalira ndi mtundu umenewu wa khansa.
Kuti afikire malingaliro ofanana, ochita kafukufuku adapanga chitsanzo chomwe chimasonyeza ubale pakati pa chiwerengero cha imfa za khansa ndi kuchuluka kwa khofi wodyedwa. Ndipo anapeza kuti ngati munthu aliyense padziko lapansi akamwa makapu awiri a khofi patsiku, anthu pafupifupi theka la milioni amafa ndi khansa ya chiwindi. Ndiye khofi ingapulumutse dziko?
Kuonjezera apo, chiwerengero chochititsa chidwi chatulukira: ambiri mwa khofi amaledzera m'mayiko a Scandinavia. Aliyense wokhala kumeneko amamwa pafupifupi makapu anayi patsiku. Ku Ulaya, amamwa makapu awiri patsiku, monga ku South America, Australia ndi New Zealand. Kumpoto ndi ku Central America, komabe, amamwa khofi wochepa - kapu chabe patsiku.
"Khofi ayenera kulimbikitsidwa monga njira yopewera khansa ya chiwindi," ofufuzawo akutsimikiza. "Ndi njira yosavuta, yotetezeka komanso yotsika mtengo yopewera kufa kwa anthu masauzande ambiri chaka chilichonse chifukwa cha matenda a chiwindi."
Zowona, asayansi nthawi yomweyo adasungitsa kuti kafukufuku wawo wokha siwokwanira: ntchitoyo iyenera kupitilizidwa kuti pamapeto pake tipeze zomwe zili zamatsenga mu khofi zomwe zimateteza ku oncology.
