Ndipo tsopano, monga kale, oncology ankaonedwa kuti ndi vuto la mankhwala padziko lonse lapansi. Ndipo matenda okhawo atangoyamba kumene ndipo chithandizo chofunika kwambiri ndi mankhwala atsopano a zaka zomaliza za kumasulidwa amathandiza kwenikweni. Koma mulimonsemo chitetezo chikhale choyenera kuteteza khansa, ndipo ili ndi zotsatirazi:
Mankhwala a khansa ndi omwe amachititsa khansa, ndipo izi zimatsimikiziridwa ndi mayesero ambiri a sayansi ndi zochitika. Lowani khansa ndi chakudya chomwe timadya. Matenda a zamoyo zimadalira mwachindunji chakudya chathu. Ngati timadya zakudya zachilengedwe zomwe ziri ndi mavitamini onse ndi kufufuza zinthu zomwe zimayenera thupi, komanso mankhwala osiyanasiyana chifukwa cha kusintha kwa thupi m'thupi, timathandizira thupi kuti lileke kukula kwa zinthu zosafunika. Asayansi atsimikizira kuti pali gulu laling'ono la ophunzira lomwe limapweteka ma jeni, likuphwanya ndondomeko yawo yotsitsa ndipo motero kumayambitsa kuyambitsa njira zopweteka. Mafakitale amenewa ndi ofanana ndi khansa.
Pakati pa ma carcinogens, "polycyclic hydrocarbons" ndiwo atsogoleri akuluakulu. Amapangidwa makamaka mu mavitamini (kuyaka) kwa zinthu zina. Pa nthawi yomweyo, nthaka, madzi, mpweya ndi chilengedwe chonse zimaipitsidwa. Kenaka mankhwalawa amasonkhanitsa zomera, zomwe zimagwiritsidwa ntchito ndi anthu ndi zinyama. Chifukwa chake, amadziunjikira m'thupi la munthu. Mwa iwo okha, polycyclic hydrocarbons mu thupi la nyama amasonkhanitsa pang'ono. Kuwonjezera pa kuchuluka kwawo kumalimbikitsidwa ndi ntchito ya munthu mwiniyo. Mwachitsanzo, pamene akusuta fodya, chiwerengero cha polycyclic hydrocarboni chimakula mochuluka. Zikuoneka kuti masentimita 50 a soseji wosuta ali ndi polycyclic hydrocarboni ngati phukusi la ndudu. Ndipo izi zimayambitsa matenda opatsirana a ziwalo za m'mimba, kupuma ndi khansa ya m'mawere.
Gulu lotsatira loopsa kwambiri ndi nitrates. Koma izi siziri nitrates, zomwe zimagwiritsidwa ntchito monga feteleza mchere muzolimo. Izi ndizo zotchedwa carcinogenic nitrate. Zimayambitsa khansara ya mavitamini, dongosolo lakumadya, khansa ya nasopharynx ndi ubongo.
Ndipo gulu lina loopsa la khansa, zomwe zimafunikila kumvetsera - mycotoxins. Makina amenewa amapanga nkhungu. Zimapangidwa chifukwa cha ntchito yawo yofunikira. Zimatipweteka kwambiri, popeza sizingaphedwe ndi kutentha kwa nthawi yayitali, sizikugwa pa kutentha. Choncho, mu khitchini mwachizolowezi, alibe njira zophikira mafuta. Iwo alibe kununkhiza, palibe kulawa ndipo amakhoza kugunda kwa maola 2-3. Kwenikweni, zimayambitsa matenda opatsirana a m'matumbo, chiwindi ndi m'mimba.
Musaiwale za khansa zomwe zimagwiritsidwa ntchito mu ulimi (pesticides, herbicides ndi fungicides). Komanso chakudya chingakhale ndi khansa zina zoopsa (radionuclides ndi salt zitsulo).
Nazi malamulo angapo omwe angathandize pang'ono kuchepetsa ngozi ya chakudya chomwe mumadya.
- Kupeza chakudya kumalo olamuliridwa, kumene kuli malo ogwiritsira ntchito malo otetezeka a epidemiological.
- Sungani zamasamba ndi zipatso mu firiji, ndipo musanayeretsenso, nthawi zonse muzimutsuka ndi madzi. Peel khungu ndi utsi wosanjikiza.
- Musagwiritse ntchito zakudya zopangidwa ndi nkhungu, zovunda ndi zowonongeka.
- Onetsetsani momwe zinthu zilili komanso zakudya zosungiramo zakudya. Samalani kwambiri ku zinthu zowonongeka.
- Mukathamanga, simungakhoze kuyembekezera kuti mafuta asute. Gwiritsani ntchito zakudya zochepa zokazinga.
- Ngati n'kotheka, musiye kusuta fodya.
- Osadya chakudya cholimbitsa (zophika za French, chips, belyashi, pies, chebureks).
- Kuwongolera mwakachetechete kudyetsa mchere wamchere ndi mafuta a nyama.
- Nthawi zonse fufuzani bowa womwe unasonkhanitsidwa ndi zipatso za ma radionuclides.
