Breast infiltrating duct carcinoma is the medical term for the most common types of cancers that occur in human cancer. To put it simply, the cancer is a cancer start in tissue that arise from cells of ectodermal and mesodermal origin embryonic mesoderm to the general, the surface of the inside or outside of the body line. In particular, were obtained from the epithelial cells to be estimated changed or damaged to the extent that such cells are transformed in their genome cancer tumor tissues, and began to show the characteristics of the abnormal malignant. The long-term cancer is unknown (see CUP) development of its ancestors and origins, malignant tumor consisting of a doll quality transformed cells with specific typical, the histological features molecules, cells and epithelial cells now included. This may include ornamental motif as a pseudo-stratified or delamination and / or production of one or more forms of intermediate filaments or other cytokeratin bridge between cells, keratin pearls, and tissue.

Cancer occurs when storing the compound biochemical other precursor cells constitute other changes to DNA and mutation, the genome of a cell and histone. The cell and other cells, the genome of the cell structure of the biochemical components is controlled by the cellular biochemical reactions occurring in the biological interactions of the cell. Taken together, it is considered to be characteristic of the cancer, the particular combination of mutations in stem cells ultimately leads (also called cancer stem cells) the cell indicates the number of abnormal and malignant cells characteristic , the number of cancer cells “daughter” of new malignant (mitosis uncontrolled) production increased (exponential or nearly) gradually can including.The, will continue to divide continuously. Ability to give birth and organization structure of the body or nearby, to penetrate the barriers and body surface in normal (local invasion). By inputting (or distant metastasis) through the vascular and / or lymphatic and (regional metastases), the ability to spread elsewhere in the body (metastasis). If you have not stopped by a combination of stimulation of medical intervention and treatment of immune defense, this process continued growth, local invasion, and distant metastasis and region, the final result, continuous load of tumor cells throughout the body by the host It is to suffer increased Na. Death occurs in the end eventually, and interference, the biochemical function of the normal authorities of the host to do more and more tumor burden.

I refers to a small, a localized prostate cancer that do not penetrate the membrane of the epithelium at the boundary of the cancer cells from normal cells (CIS) or term of carcinoma in situ are adjacent to each other still. Rather than invasive cancer in advance, CIS is a pre-malignant human. Until it begins to penetrate and infiltrate through the structure of adjacent / or other basement membrane with them, in the case of almost all of the CIS, we will continue to grow and develop. After the invasion happened, they do not think the CIS lesions longer, but it is invasive cancer really. Before and metastasis frank invasion will develop, it is not possible for you to be removed in the target treatment other areas of some damage surgical resection completely, cryotherapy, or laser ablation,, cure rate CIS 100% I approaches.

In some cases, as it may histological characteristics and cytological appear more normal again assumed system lesions gradually, it is a low-grade tumor. Biologically, this can lead a less often aggressive, to slow tumor growth. In fact, the emergence of local tissue architecture and components of the Local Site CIS may be normalized to a point that does not meet the required consensus requirements to be classified as a cancer longer transformed cells eventually. Therefore, this anomaly is not allowed as a true cancer.
The change of these, decrease the normal area, and I’m with the volume of place or abnormal /. The number that can not be ignored or some cases, the abnormal cells / tissue, may disappear the region obtained including the organization that looks normal only in full. In many cases, the process is referred to by the pathologist as regression and specialist of the CIS lesion. Without connective tissue, associated, which is formed as a result of fibrosis apoptosis and necrosis often effective, involution CIS is gradual transformation of malignant tumor benign localized region of tissue near-normal or normal I bring.

Regression occurs after prolonged exposure to changes in the strength and quality of immunological stimulation and environment most often and / or. In the example a very common, it is a regression of the disease of the CIS some located in the segmental bronchi and the main center of the lung. Invasive lesions of many conventional in the case of squamous cell carcinoma, reduced regression to the following long-term exposure of cells and tissues affected by the stimulation of the initial environmental carcinogen with what you see in abstinence after a long period of time from smoking like this often. A common example of a relatively different, causing regression of cervical CIS lesions, it is end is driven immunologically of human papillomavirus HPV by epithelial cells that have been converted of the cervix.
