The disease before cancer reachs the pathological changes before cancer
The pathological changes before the disease before cancer and cancer is the disease that points to to apparent canceration risk is had on certain statistic and pathological changes, if be cured not in time,transform likely namely for cancer. Accordingly, inchoate discovery and the pathological changes before the disease before curing cancer in time or cancer, have important real sense to the precaution of tumor. The disease before common cancer and pathological changes have the following kinds:
(Blaze of 1) mucous membrane: Often happen in the place mucous membrane such as esophagus, oral cavity, cervix and vulva. Epithelial and excessive hyperplasia and excessive horn change the scale condition that main pathology change is mucous membrane, the different with appear certain sex. White spot is shown on naked eye piece, friend says blaze. If do not heal for a long time,possible change is cancer of scale shape cell.
(Debaucjed of neck of palace of phlogistic companion of neck of 2) slow coach palace: It is the woman's common disease suffers from. The scale shape in ministry of vagina of the cervix on the foundation with chronic phlogistic cervix is epithelial be come from inside cervix canal columnar and epithelial place replaces velar monolayer, make the place is shown pink or vermeil, seemed to produce mucous membrane to be short of caustic epithelially, call cervix rotten to the core. Subsequently, local but by reborn scale shape epithelial place is replaced, call erosion to heal answer. If afore-mentioned processes undertake repeatedly, criterion a few case of illness is cancer of cell of cervix scale shape changeably.
(Mammary gland of sex of 3) fiber bursa is ill: This disease is caused by endocrinopathy, common the woman that controls at 40 years old, main show is gland of the hyperplasia with conduit of mammary gland flocculus and gland epithelial bubble, kubla khah to change unripe reach dilate of tracheal bursa sex, qualitative fibre also has proliferation between. The person that companion has proliferation of shape of tracheal endosperm head produces canceration more easily.
(Sex of adenoma of 4) colon, anal is polypous: Relatively common, can single shot or much hair, all can produce canceration. The person that send a gender more often has familial history, produce canceration more easily.
(Gastritis of sex of 5) chronic atrophy reachs gastric ulcer: When gastritis of chronic and atrophic sex, body of gland of gastric mucous membrane can have bowel epithelial change unripe, this kind of bowel is epithelial change be born to have particular concern with the happening of cancer of the stomach, be like long treat can not produce canceration more. Because the mucous membrane of brim of the ulcer when chronic gastric ulcer suffers exciting and ceaseless hyperplasia, thought to 5% may transform in the past for cancer, think its canceration rate is about now 1% .
(Colonitis of sex of 6) chronic ulcer: Relapse in ulcer and colonic gland cancer can happen on the foundation of mucous membrane hyperplasia.
(7) skin is chronic ulcer: The skin ulcer that prolonged does not heal and fistula, especially the chronic ulcer of crus, because be stimulated for a long time chronically, cuticular scale shape is epithelial and proliferous, some can produce canceration.
But must point out, cancerous formation often experiences endless, gradually the process of gradual progress, it is 15 ~ on average 20 years, and the disease before be not all cancer and pathological changes transform necessarily for cancer, this still depends on a lot of elements. Also be not the disease before all cancer already discovered clear cancer at present moreover, the research of this respect has important sense on the precaution of tumor.
