Un Ka maʻi 'aʻai ʻo ia hoʻi ke kū ʻana o nā hunaola ʻino e hoʻonui nei i kahi mana i kaohi ʻole ʻia. I ka hihia o umauma maʻi 'aʻai, hiki i nā pūnaewele ke noho i ka umauma a laha paha i ke kino ma o ke koko a i ʻole nā ​​kīʻaha lymph. ʻO ka hapa nui o ka manawa, holo ka holomua o ka maʻi ʻaʻai umauma i mau mahina a i kekahi mau makahiki.

Le umauma maʻi 'aʻai ʻo ia ka maʻi ʻaʻai i ʻike nui ʻia i nā wahine a puni ka honua, ma mua a ma hope hoʻi o ka menopause¹. A wahine i 9 wahine e ulu i ka maʻi 'aʻai umauma i ko lākou ola a 1 i 27 mau wahine e make ai ia.

ʻO ka hapanui pinepine, loaʻa ka maʻi ʻaʻai umauma ma hope o 50 mau makahiki. ka helu ola 5 mau makahiki ma hope o ka hōʻoia ʻana mai 80% a 90%, kaukaʻi ʻia i ka makahiki a me ke ʻano o ka maʻi ʻaʻai.

Ua piʻi iki ka nui o ka poʻe i hoʻopilikia ʻia akā hoʻomau mau i nā makahiki he 3 i hala. Ma ka ʻaoʻao ʻē aʻe, ka manawa make kino ua hōʻole mau i ka manawa like, mahalo i ka holomua i loko wehewehe, diagnose a me ka lāʻau.

E haʻi mākou i ka na kanaka hiki ke hoʻopili ʻia; pani lākou i 1% o nā hihia āpau.

Umauma

Le umauma Aia i loko o nā momona, nā glands a me nā duct (e nānā i ke kiʻikuhi ʻē aʻe). Hoʻonohonoho ʻia nā glands, hoʻonohonoho ʻia i nā lobule, hana i ka waiu a me nā kahawai (nā wai lactation a i ʻole nā ​​wai waiū) lawelawe i ka lawe ʻana i ka waiū i ka ke kui. Hoʻohuli ʻia nāʻiʻo umauma e nā hormones i hana ʻia e nā wahine i nā nui like ʻole i loko o ko lākou ola (ʻōpio, hāpai keiki, hānai waiū, a pēlā aku.). ʻO kēia mau hormones ʻo estrogen a me progesterone.

Nā ʻano o ka maʻi ʻaʻai umauma

Hoʻolālā nā ʻano like ʻole o ka maʻi ʻaʻai umauma i nā ʻano like ʻole:

Hoʻokomo kēia mau ʻano maʻi ʻaʻai i ka nā lole a puni nā kahe lactation, akā noho i loko o ka umauma. Ma ka ʻaoʻao ʻē aʻe, inā ʻaʻole mālama ʻia ka tumo, hiki ke pālahalaha i nā ʻāpana ʻē aʻe o ke kino (e laʻa me nā iwi, nā akemāmā a me ke akepaʻa) e hana ana i nā metastases.

• Kanu maʻi maʻi. Hana ia i nā kahena lactation. Hele nā ​​pūnaewele maʻi maʻi ma ka paia o nā auwaha;
• Carcinoma Lobular. ʻIke ʻia nā hunaola maʻi ʻaʻai i loko o nā lobule i hui pū ʻia i nā puʻupuʻu. A laila, hele lākou i ka paia o nā lobule a hoʻolaha i nā a puni;
• Carcinoma hoʻāla. ʻO kahi maʻi ʻaʻai liʻiliʻi e hōʻike nui ʻia e ka umauma i hiki ke lilo ʻulaʻula, pehu et wela. Hiki i ka ʻili o ka umauma ke lawe i ka hiʻohiʻona o kahi ʻalani ʻalani. Holomua kēia ʻano maʻi ʻaʻai a ʻoi aku ka paʻakikī o ka mālama ʻana;
• ʻO nā carcinomas ʻē aʻe (medullary, colloid or mucinous, tubular, papillary). He ʻano rarer kēia ʻano maʻi ʻaʻai o ka umauma. ʻO nā ʻokoʻa nui ma waena o kēia ʻano maʻi ʻaʻai e pili ana i ke ʻano o nā hunaola i hoʻopili ʻia.

Nā kumu

Nui a hewahewa nā mea i ʻike ʻia no umauma maʻi 'aʻai. Eia nō naʻe, i ka hapanui o nā hihia hiki ʻole ke wehewehe i nā kumu no ka hanana ʻana i loko o kekahi kanaka.

maika nā hoʻololi i nā gen, i hoʻoili ʻia i kēlā hanauna i kēia hanauna a i loaʻa paha i loko o kahi ola (ʻike ʻia i ka radiation a i ʻole kekahi mau lāʻau ʻona, e laʻa, hiki ke hoʻololi i nā genes), hiki ke loaʻa i ka maʻi ʻaʻai umauma. ʻO nā gene BRCA1 a me BRCA2, no ka laʻana, he mau ʻāpana no ka maʻalahi i umauma a me ovarian maʻi 'aʻai. ʻO nā wahine e hāpai i nā mutation i kēia mau genes i kahi makaʻu nui loa i ka maʻi ʻaʻai.
