Patofisiologi kanker payudara nuduhake owah-owahan abnormal ing proses fisiologis normal lan mekanisme sing kedadeyan ing pangembangan lan perkembangan kanker payudara.
Iki kalebu panliten mekanisme biologis lan molekuler sing nyebabake tuwuh lan nyebar sel kanker sing ora dikendhaleni ing jaringan payudara.
Iki kalebu faktor genetik, epigenetik, lan lingkungan sing nyumbang kanggo wiwitan, promosi, lan perkembangan kanker payudara.
Sawetara owah-owahan patofisiologis utama ing kanker payudara kalebu:
1. Mutasi genetik: Mutasi ing gen tartamtu, kayata BRCA1 lan BRCA2, bisa nambah risiko ngalami kanker payudara.
Mutasi kasebut bisa diwarisake utawa dipikolehi sajrone urip wong.
2. Ketidakseimbangan hormon: Hormon, utamane estrogen, bisa duwe peran ing pangembangan lan tuwuhing kanker payudara.
Ketidakseimbangan tingkat hormon utawa paparan estrogen sing kakehan bisa nambah risiko kanker payudara.
3. Peradangan: Peradangan kronis ing jaringan payudara bisa nyumbang kanggo pangembangan kanker payudara kanthi ningkatake tuwuh lan kaslametan sel kanker.
4. Lingkungan mikro tumor: Lingkungan sing ngubengi tumor, kalebu matriks ekstraseluler, sel kekebalan, lan pembuluh getih, bisa mengaruhi tuwuh lan nyebar kanker payudara.
5. Metastasis: Kanker payudara bisa nyebar menyang bagean awak liyane liwat sistem limfatik utawa aliran getih, sing nyebabake pembentukan tumor sekunder ing organ sing adoh.
Ngerti patofisiologi kanker payudara penting banget kanggo ngembangake strategi pencegahan, deteksi awal, lan perawatan sing efektif.

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.
