The cause of disease pathology of cervical cancer

Cause of disease
The temple neck cancer really slices a cause of disease not clear.According to census and clinical data analyze, outbreak with early marry, early teach, much teach, sex life the mess and chronic temple neck is burning relevant.The research detection of recent years grows the Ⅱ type of a pimple rash virus(HSV-Ⅱ ) and mankind nipple-like in shape lump virus(HPV) and mankind the big and small afterbirth virus(CMV) infection may be the particularity of temple neck cancer plain to the cause of disease, as well someone thinks that excrescent DNA that mutates sperm gets in to can induct tumor formation on the chromosome of skin cell of temple neck.Occurrence and the development temple neck cancer of temple neck cancer start hair part much scale-like in shape in the temple neck vagina department up the epithelial the skin and the temple neck tube pillar hand over boundary.At cause cancer the incitement of factor under, the temple neck is scale-like in shape to increase a life to jump and divide badly up the skin first floor cell and form gradually skin of temple neck not the typical model increase to living, never the typical model increase to living to develop into the home position cancer gradually, in early days gradually cancer and gradually cancer.Not the typical model increases to living in order to expect a pathological changes before the cancer, can exist very long time(on the average about 4 years), can recover as usual, can also develop into the home position cancer.Not the typical model increases to living to be limited by with the pathological changes of home position cancer all skin of temple neck inside, often match to call lump formation(CIN) inside the skin of temple neck to discriminate between gradually a cancer.Never the typical model increases to living to arrive gradually cancer is a slow-moving but gradually enter of process, usually need 8~10 years, once formation gradually the cancer then grow quickly, if don't cure in time, the sufferer dies in 2~5 years.
Pathology
The cervical cancer regards scale-like in shape cell cancer as principle and has 95% around, the gland cancer is or so for 5%.Gland scale the cancer is seldom seen, but the malignant degree is the tallest, to empress the worst.
(A)huge check
Skin of temple neck not the typical model increase to living, home position cancer and in early days gradually cancerous external appearance, basic normal or similar temple neck was debauched.Gradually the cancer then can have following 4:
1.The debauched type temple neck is harder grain-like in shape debauched, touch of easy issue of blood;
2.Outside living a type the growth is toward the vagina direction and present the form of condy-loma accuminata, quality frailty, often the companion surface Be bad to die and be infected after the hair;
3.Inside living a type to grow to the temple neck deep department, the temple neck is fatty big and hard, but the external appearance is still smooth;
4.The empty type cancer organizes bad dead to shed off, can form empty.
(Two)the microscope check
1.Not the typical model increases to living
The first floor cell increases to living, from the normal 1~2 F cell increase a layer at most, remain in an immaturity stage.In order to turn badly, the cell arranges mess and checks a syrup comparison to disorder and check size the etc. dye deeply not, check the silk cent type to increase.The surface layer cell divides maturity.Not the typical model increases to living to is divided into lightly, medium, weigh three degrees.Light degree:Not the typical model cell doesn't exceed last the skin whole layer of of descend 1/3, divide better;Mid-degree:Not the typical model cell doesn't exceed last the skin whole layer of of descend 2/3, divide worse;Heavy degree:Not the typical model cell exceeds last the skin whole layer of of descend 2/3, divide to differ most , surface layer cell mature, turn cell for 1 F or several Capes, have differentiation with home position cancer.Light degree not the typical model increase to living often for can go against of, but heavy degree not the typical model increase to living to make progress into the home position cancer of possibility bigger.
2.Home position cancer
Scale-like in shape up the skin whole layer all is a cancer cell, but the base film is complete, the quality is free from invasion;
3.In early days gradually cancer
On the foundation of home position cancer, a little amount cancer cell once wears base film but irruptive quality, gradually depth at 5 mms in, have no afferent and(or) lymphoid tube invasion, and cancer cooking stove have no fusion phenomenon;4.Gradually the cancer cancer cell once wears a base film, incursion the scope of the quality is more wide, gradually the depth is above in the 3 mms, and have afferent and(or) lymphoid tube invasion.
