What is DCIS? Epithelial cancer carcinoma in situ is confined to the skin or mucosa, but not through the basement membrane under the skin or mucous membrane, violations to the surrounding tissue. If left untreated, can develop into invasive cancer.
What is carcinoma in situ, carcinoma in situ, also called "intraepithelial carcinoma" is the proliferation of epithelial cells to the early stages of malignant transformation. Epithelial tissue covering the body surface and body organs, the outer surface layer of organizations, including the number of epithelial cells and basement membrane layer. The following is the interstitial and dermal tissue. Carcinoma in situ refers to cancer cells only in the cortex. Without damage to the basement membrane, or invade the stroma under or dermis. And no invasion and distant metastasis occurs, it is sometimes called carcinoma in situ "before invasive cancer" or "0 cancer."
Carcinoma in situ is the earliest, it is also known cancers, this time as surgery to completely heal. Common in cervical carcinoma in situ, skin, bronchus, stomach, prostate, and breast and other parts. If the lesions in the skin, also known as Bowen (Bowen) disease, or intraepithelial carcinoma. Can occur in any part of the skin, more common in the elderly, and occasionally occurred in the skin and conjunctiva at the junction of tumor and adjacent normal tissue circumscribed, slow development can be a number of years confined to the epithelium. Plus untreated can develop into squamous cell carcinoma.
Carcinoma in situ, early invasive carcinoma can be further developed, and occasionally in situ can be dissipated. Although carcinoma in situ lesions limitations, but also multi-focal or do not penetrate the basement membrane in the case involving a large area.
What is carcinoma in situ, a common carcinoma in situ of skin carcinoma in situ, cervical carcinoma in situ, carcinoma in situ of the stomach, rectum carcinoma in situ, intraductal carcinoma and lobular breast carcinoma in situ between. Because invasion and metastasis of carcinoma in situ have not formed, does not meet the characteristics of cancer, so it is not real "cancer." If we can discover as soon as possible to remove or to other appropriate treatment, the purpose of cure can be achieved. The so-called early detection of cancer, carcinoma in situ of the best is found, then treatment with excellent results. For example, the earliest of cervical cancer is carcinoma in situ, the patient no symptoms, the naked eye can not see cancer, cervical cancer screening by using the method of cervical smear can find it, if timely treatment. Cure rate of up to 100%.
