Carcinoma is a malignancy that develops from epithelial cells. [1] Specifically, a carcinoma is a cancer that begins in a tissue that lines the inner or outer surfaces of the body, and that arises from cells originating in the endodermal, mesodermal [2] or ectodermal germ layer during embryogenesis. [3]
Once a cancer has metastasized, prognosis normally becomes much worse. About half of patients receiving treatment for invasive cancer (excluding carcinoma in situ and non-melanoma skin cancers) die from that cancer or its treatment. [25] A majority of cancer deaths are due to metastases of the primary tumor. [203]
Electrochemotherapy is the combined treatment in which injection of a chemotherapeutic drug is followed by application of high-voltage electric pulses locally to the tumor. The treatment enables the chemotherapeutic drugs, which otherwise cannot or hardly go through the membrane of cells (such as bleomycin and cisplatin), to enter the cancer cells.
Cancer treatments are a wide range of treatments available for the many different types of cancer, with each cancer type needing its own specific treatment. [1] Treatments can include surgery, chemotherapy, radiation therapy, hormonal therapy, targeted therapy including small-molecule drugs or monoclonal antibodies, [2] and PARP inhibitors such as olaparib. [3]
Potentially-malignant neoplasms include carcinoma in situ. They are localised, and do not invade and destroy but in time, may transform into cancer. Malignant neoplasms are commonly called cancer. They invade and destroy the surrounding tissue, may form metastases and, if untreated or unresponsive to treatment, will generally prove fatal.
The TNM Classification of Malignant Tumors (TNM) is a globally recognised standard for classifying the anatomical extent of the spread of malignant tumours (cancer). It has gained wide international acceptance for many solid tumor cancers, but is not applicable to leukaemia or tumors of the central nervous system.
Treatment for melanoma depends on how advanced it is and where the tumor is located. McMichael says doctors will look at the tumor’s depth, how quickly cells are dividing and other factors to ...
If cancer has spread beyond that, it is said to be ES. Lung cancer is the leading cause of cancer-related deaths worldwide, accounting for the highest mortality rates among both men and women. When associated with the lung, SCLC is sometimes called "oat cell carcinoma" due to the flat cell shape and scanty cytoplasm. Small cell mesothelioma ...
