Iyini i-pathophysiology yomdlavuza webele?

I-pathophysiology yomdlavuza webele ibhekisela ekushintsheni okungajwayelekile ezinqubweni nasezinhlelweni ezijwayelekile zomzimba ezenzeka ekuthuthukiseni nasekuthuthukiseni umdlavuza webele.

Kuhilela ukutadisha izindlela eziyisisekelo zezinto eziphilayo nezama-molecule eziholela ekukhuleni nasekusakazekeni okungalawuleki kwamangqamuzana omdlavuza ezicutshini zamabele.

Lokhu kuhlanganisa izici zofuzo, ze-epigenetic, nezemvelo ezifaka isandla ekuqaliseni, ekuthuthukiseni nasekuthuthukiseni umdlavuza webele.

Ezinye zezinguquko eziyinhloko ze-pathophysiological kumdlavuza webele zihlanganisa:

1. Ukuguquguquka kwezakhi zofuzo: Ukuguquguquka kwezakhi zofuzo ezithile, njenge - BRCA1 ne - BRCA2, kungandisa ingozi yokuthola umdlavuza webele.

Lokhu kuguquka kwezakhi zofuzo kungadluliselwa njengefa noma kutholakale phakathi nokuphila komuntu.

2. Ukungalingani kwama-hormone: Ama-hormone, ikakhulukazi i-estrogen, angadlala indima ekwakhiweni nasekukhuleni komdlavuza webele.

Ukungalingani kwamazinga e-hormone noma ukuchayeka ku-estrogen eyeqile kungandisa ingozi yomdlavuza webele.

3. Ukuvuvukala: Ukuvuvukala okungapheli kwezicubu zamabele kungasiza ekuthuthukiseni umdlavuza webele ngokukhuthaza ukukhula nokusinda kwamangqamuzana omdlavuza.

4. Imvelo encane yesimila: Imvelo ezungeze isimila, kuhlanganise ne-extracellular matrix, amangqamuzana omzimba, nemithambo yegazi, ingathonya ukukhula nokusakazeka komdlavuza webele.

5. I-metastasis: Umdlavuza webele ungasakazekela kwezinye izingxenye zomzimba nge-lymphatic system noma ngegazi, uholele ekwakhekeni kwamathumba wesibili ezingalweni ezikude.

Ukuqonda i-pathophysiology yomdlavuza webele kubalulekile ekwakhiweni kwamasu asebenzayo okuvimbela, okutholakala kusenesikhathi, nokwelashwa.

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 breast cancer?

Pathophysiology of breast cancer refers to the abnormal changes in the normal physiological processes and mechanisms that occur in the development and progression of breast cancer.

It involves the study of the underlying biological and molecular mechanisms that lead to the uncontrolled growth and spread of cancer cells in the breast tissue.

This includes the genetic, epigenetic, and environmental factors that contribute to the initiation, promotion, and progression of breast cancer.

Some of the key pathophysiological changes in breast cancer include:

1. Genetic mutations: Mutations in certain genes, such as BRCA1 and BRCA2, can increase the risk of developing breast cancer.

These mutations can be inherited or acquired during a person's lifetime.

2. Hormonal imbalances: Hormones, particularly estrogen, can play a role in the development and growth of breast cancer.

An imbalance in hormone levels or exposure to excess estrogen can increase the risk of breast cancer.

3. Inflammation: Chronic inflammation in the breast tissue can contribute to the development of breast cancer by promoting the growth and survival of cancer cells.

4. Tumor microenvironment: The environment surrounding the tumor, including the extracellular matrix, immune cells, and blood vessels, can influence the growth and spread of breast cancer.

5. Metastasis: Breast cancer can spread to other parts of the body through the lymphatic system or bloodstream, leading to the formation of secondary tumors in distant organs.

Understanding the pathophysiology of breast cancer is crucial for developing effective prevention, early detection, and treatment strategies.
