Iyini i-pathophysiology yomdlavuza wamaphaphu?

I-pathophysiology yomdlavuza wamaphaphu ibhekisela ekushintsheni kwezinqubo ezivamile zomzimba nezindlela ezenzeka ekuthuthukiseni nasekuthuthukiseni umdlavuza wamaphaphu.

Umdlavuza wamaphaphu uyisifo esiyinkimbinkimbi esivela ekukhuleni nasekuhlukaneni okungalawuleki kwamangqamuzana angavamile emaphashini.

La maseli angakha izimila futhi asakazekele kwezinye izingxenye zomzimba, okuholele ezinhlotsheni ezihlukahlukene nezinkinga.

I-pathophysiology yomdlavuza wamaphaphu ihilela izici eziningana, kuhlanganise nokuguquka kwezakhi zofuzo, izici zemvelo, nokukhetha indlela yokuphila.

Ukuguquguquka kwezakhi zofuzo kungase kwenzeke ku-DNA yamangqamuzana amaphaphu, okuholele ekukhuleni kwamangqamuzana nasekwahlukaneni kwawo okungalawuleki.

Lezi zinguquko zingazuzwa njengefa noma zitholakale, futhi zingabangelwa ukuchayeka ezintweni ezibangela umdlavuza, njengentuthu kagwayi, i-radon, i-asbestos, nokungcola komoya.

Umdlavuza wamaphaphu ungahlukaniswa ngezinhlobo ezimbili eziyinhloko: umdlavuza wamaphaphu wamangqamuzana amancane (SCLC) nomdlavuza wamaphaphu wamangqamuzana amancane (NSCLC). I-NSCLC ihlukaniswe yaba izinhlobo ezintathu: i-adenocarcinoma, i-squamous cell carcinoma, ne-large cell carcinoma.

I-pathophysiology yalezi zinhlobo zomdlavuza wamaphaphu ingahluka, njengoba zinokuguquguquka kofuzo okuhlukile futhi ziphendula ngokuhlukile ekwelapheni.

I-pathophysiology yomdlavuza wamaphaphu ihilela nokusebenzisana phakathi kwamangqamuzana omdlavuza nezicubu ezizungezile, kuhlanganise nesimiso sokuzivikela komzimba.

Amangqamuzana omdlavuza angakwazi ukugwema isimiso somzimba sokuzivikela ezifweni, avumele ukuba akhule futhi asakazeke ngaphandle kokulawulwa.

Ngaphezu kwalokho, i-microenvironment ye-tumor ingakhuthaza ukukhula kwe-tumor kanye ne-metastasis ngokunikeza imvelo esekelayo kumaseli omdlavuza.

I-pathophysiology yomdlavuza wamaphaphu iyinqubo eyinkimbinkimbi futhi eguquguqukayo, futhi abacwaningi basebenza ngokuqhubekayo ukuze baqonde kangcono izindlela eziyisisekelo zokuthuthukisa ukwelashwa okuphumelelayo nokwenza ngcono imiphumela yeziguli.

Ukuzikhulula: kwezokwelapha

Le webhusayithi inikezwa ngezinjongo zemfundo nezokwaziswa kuphela futhi ayifaki ukunikeza izeluleko zezokwelapha noma izinsizakalo zobungcweti.

Imininingwane enikeziwe akufanele isetshenziselwe ukuxilonga noma ukwelapha inkinga noma isifo, futhi labo abafuna iseluleko somuntu siqu sezokwelapha kufanele babonane nodokotela onelayisense.

Sicela uqaphele ukuthi inethiwekhi ye-neural ekhiqiza izimpendulo zemibuzo, ayinembile ngokukhethekile uma kuziwa kokuqukethwe kwezinombolo. Ngokwesibonelo, inani labantu abanesifo esithile.

Ngaso sonke isikhathi funa iseluleko sikadokotela wakho noma omunye umhlinzeki wezempilo ofanelekayo mayelana nesimo sezokwelapha. Ungalokothi ungayinaki iseluleko sezokwelapha sobungcweti noma ubambezele ukusifuna ngenxa yento oyifundile kule webhusayithi. Uma ucabanga ukuthi ungase ube nesimo esiphuthumayo sezokwelapha, shayela i-911 noma uye egumbini lezimo eziphuthumayo eliseduze ngokushesha. Ayikho ubudlelwano bokuthi udokotela-isiguli obakhiwe yile webhusayithi noma ukusetshenziswa kwayo. I-BioMedLib noma abasebenzi bayo, noma noma yimuphi umnikeli wale webhusayithi, akenzi noma yimiphi imibono, ecacile noma ecacile, mayelana nolwazi olunikezwe lapha noma ukusetshenziswa kwayo.

Ukuzikhulula: amalungelo obunikazi

I-Digital Millennium Copyright Act ka-1998, i-17 U.S.C. § 512 (i- DMCA) inikeza indlela yokuphendula kubanikazi bamalungelo obunikazi abakholelwa ukuthi okokusebenza okubonakala kwi-Internet kwephula amalungelo abo ngaphansi komthetho we-copyright wase-US.

Uma ukholelwa ngobuqotho ukuthi noma yikuphi okuqukethwe noma okokusebenza okwenziwe kutholakale maqondana newebhusayithi yethu noma izinsizakalo kwephula ilungelo lakho lobunikazi, wena (noma umenzeli wakho) ungasithumela isaziso esicela ukuthi okuqukethwe noma okokusebenza kususwe, noma ukufinyelela kukho kuvinjelwe.

Izaziso kufanele zithunyelwe ngokubhala nge-imeyili (bheka isigaba esithi "Contact" ukuze uthole ikheli le-imeyili).

I-DMCA idinga ukuthi isaziso sakho sokwephulwa kwamalungelo obunikazi kubandakanye imininingwane elandelayo: (1) incazelo yomsebenzi onamalungelo obunikazi oyisihloko sokwephulwa okusolwa; (2) incazelo yokuqukethwe okusolwa ukwephula amalungelo obunikazi nolwazi olwanele ukusivumela ukuthi sithole okuqukethwe; (3) imininingwane yokuxhumana nawe, kufaka phakathi ikheli lakho, inombolo yocingo nekheli le-imeyili; (4) isitatimende sakho sokuthi unokholo oluhle lokuthi okuqukethwe ngendlela ekhonjiwe ngayo akugunyaziwe ngumnikazi wamalungelo obunikazi, noma umenzeli wakhe, noma ngokusebenza kwanoma imuphi umthetho;

(5) isitatimende sakho, esisayinwe ngaphansi kwesijeziso sokufakaza amanga, sokuthi ukwaziswa okusesazisweni kunembile nokuthi unegunya lokuphoqelela amalungelo obunikazi okuthiwa aphuliwe;

futhi (6) isignesha ebonakalayo noma ye-elekthronikhi yomnikazi we-copyright noma umuntu ogunyaziwe ukuba asebenze egameni lomnikazi we-copyright.

Ukwehluleka ukufaka yonke imininingwane engenhla kungaholela ekubambezelweni kokucutshungulwa kwesikhalazo sakho.

What is pathophysiology of lung cancer?

The pathophysiology of lung cancer refers to the changes in the normal physiological processes and mechanisms that occur in the development and progression of lung cancer.

Lung cancer is a complex disease that arises from the uncontrolled growth and division of abnormal cells in the lungs.

These cells can form tumors and spread to other parts of the body, leading to various symptoms and complications.

The pathophysiology of lung cancer involves several factors, including genetic mutations, environmental factors, and lifestyle choices.

Genetic mutations can occur in the DNA of lung cells, leading to uncontrolled cell growth and division.

These mutations can be inherited or acquired, and they can be caused by exposure to carcinogens, such as tobacco smoke, radon, asbestos, and air pollution.

Lung cancer can be classified into two main types: small cell lung cancer (SCLC) and non-small cell lung cancer (NSCLC). NSCLC is further divided into three subtypes: adenocarcinoma, squamous cell carcinoma, and large cell carcinoma.

The pathophysiology of these types of lung cancer can differ, as they have different genetic mutations and respond differently to treatment.

The pathophysiology of lung cancer also involves the interaction between cancer cells and the surrounding tissue, including the immune system.

Cancer cells can evade the immune system, allowing them to grow and spread unchecked.

Additionally, the tumor microenvironment can promote tumor growth and metastasis by providing a supportive environment for cancer cells.

The pathophysiology of lung cancer is a complex and dynamic process, and researchers are continuously working to better understand the underlying mechanisms to develop more effective treatments and improve patient outcomes.
