Mammary glands cancer cause of disease and cent type

The mammary glands cancer is one of the most familiar malignant tumor for females, the outbreak leads an only next to cervical cancer.The outbreak rate, death rate of the mammary glands cancer all is ranked high with Western Europe and North America first, but Asia, Latin America and Africa are lowest, but the recent years statisticses data to express to increase high trend.
[Cause of disease]
Mammary glands cancer also the elephant other malignant tumors are similar, the real cause of disease is still not clear.But pass foundation with clinical research, a great deal of Epidemiology survey, analysis, have already known many occurrence developments that the factor can influence a mammary glands cancer, study a little bit extensively thorough of endocrine, heredity and virus of three kinds of to cause of disease vegetable.
1, sex hormone mess:Estrogen(is particularly female two Chunses), urge a milk vegetable to test in the animal in have already confirmed a cancer-causing function.The mammary glands cancer mainly takes place in the women, good hair in unique through front, after and menarche early, cut off through the women in night.When two side ovaries don't develop or have already made a surgical operation excision, the outbreak rate of mammary glands cancer obviously descends.In addition with skin quality the hormone metabolize mess and the outside source the estrogen also have a certain relation.
2, inherit a factor:The women who have the mammary glands cancer the family history are taken bad an opposite risk, at unique through ex- and unique through after distinguish to 2.4 with 1.7.(normal women is 1)Particularly the mother and the sisterses in the relatives all at cut off through the women of ex- occurrence double side mammary glands cancer, it at 40 suffer from the probability of mammary glands cancer before the year olds the increment is consumedly.
3, the virus Be cancer-causing to have already tested in the confirmation in the animal, however organize with mammary glands cancer inside the person's human milk in also see a B type virus kind grain, but someone holds a negative attitude and also have no enough Epidemiology proof up to now to confirm it.
Someone thinks breast cancer outbreak and life style, food, nourishment, hot card, fat etc. closely relevant.
[The pathology categorizes]
Breast cancer organizes appearance more complicated, the type is usually numerous, and organize in the same cancer in, even inside the same slice can exist more than two kinds of types in the meantime.The pathology classification of international and local breast cancer is physically applying to not yet unify currently.The pathology of local breast cancer is categorized as follows:
1, not and gradually sex cancer:Point cancer lump at the earliest stage stage, the pathological changes limited at inside mammary glands pipe or gland bubble and called while doing not break a base film the cancer isn't and gradually.
1)little leaf home position cancer:Originate little leaf's pipe and don't the Shao pipe epithelial cancer, take up 1.5% of the mammary glands cancer around.Slice noodles to present the pink translucent slightly hard grain-like in shape area, the pathological changes mostly presents many cooking stoves, cancer cell the physical volume is bigger, the appearance is consistent, but arranges mess, the pipe surroundings base film integrity, often involve in a pair of sides, develop slowness.
2)cancer inside the pipe:At the home position cancer of pipe in the center, the occurrence's pathological changes can involve in pipe scope wide or present many centers, spread is distributing, slice noodles to present grain-like in shape take a grey or thin yellow a little bit small, such as skin pimple kind contents.
2, in early days gradually cancer:From not and gradually sex cancer's arriving gradually sex cancer is the process of one gradual development.The in the interval passes by in early days gradually stage, according to the dissimilarity of appearance, was divided into 2 types.
1)in early days gradually little leaf's cancer:The little leaf home position cancer once wears a base film, to in the little leaf quality gradually, but haven't gradually gone to little leaf's scope outside.
2)in early days gradually pipe cancer:The cancer inside the pipe a little amount cancer cell breaks a pipe base film, to quality gradually, but gradually the scope is small.
3, gradually sex cancer cancer organization to is inside the quality form the quality mutually mixed picture of various appearance cancer organization and extensively and gradually.Gradually the type cancer is again divided into sex special type gradually cancer and gradually sex not only and extremely type cancer.Gradually sex not only and extremely type cancer and then organize according to the cancer with a quality comparison the amount is divided into:The pure cancer, hard cancer and Sui kind cancer.
1)gradually sex not only and extremely type cancer:
The ① pure cancer:More the half see, having a mammary glands cancer around is above.Cancer's organizing main quality and quality composition is close, the cancer cell often gathers together into small nest, slice-like in shape or thick Suo-like in shape.
The ② hard cancer:10% that has mammary glands cancer total amount around is or so, the cancer main quality is little, and the quality is much characteristics.The physical volume is small, the quality is hard and slice noodles porcelain white, the cancer edge presents a crab foot-like in shape toward the surroundings is gradually.
The ③ Sui kind cancer:Have breast cancer to amount 10~20% around, cancer's organizing main quality is many, the quality is little.The lump body can reach a huge physical volume and slice the noodles grey color, department in the center often has bad dead.According to lymphoid cell in quality gradually the dissimilarity of degree, can is divided into two second types:The lymphoid cell is gradually little is the kind cancer of Huang Xing Sui not, gradually manies is the typical model Sui kind cancers.The latter after preparing good often rows into a special type gradually inside the cancer.
2)gradually sex special type cancer
The ① nipple-like in shape cancer:The big cancer inside the pipe is rarely turned into by nipple-like in shape lump inside the big pipe.Be seen to 50~60-year-old women more, lump list hair or much hair, the part has nipple to overflow a liquid, mostly guts, overflowing a liquid Tu Pian can find out cancer cell.Slice noodles to assume the palm tree red knot stanza, quality frailty, knot to have the pink Fu the meat kind inside the stanza or nipple-like in shape organization.This cancer growth slow-moving, transfer also compare night.When the cancer is substantial half above express for the gland take care of kind structure, can diagnose for the gland cancer.
The ② glues liquid gland cancer:And then gum kind cancer, less see.Being taken bad age is old and grow slowness, the state is clear and slice the noodles translucent gum jelly kind thing and have in the cancer organization abundant glue a liquid, the malignant degree is lower, the armpit lymph transfers less see.
The ③ eczema kind cancer:Call mammary glands to send a hero again surname disease.This cancer appearance last characteristic is:The nipple, the milk dizzy skin presents eczema kind to change and appears inside the epidermis a kind of big but have a characteristic parties the hero the surname cell.This cancer majority of cancers inside the merger pipes and little leaf home position cancer, the part is gradually sex pipe cancer etc..
