About Cancer and Cancer Treatment
By cancer there is an uncontrolled proliferation and growth of cells in some place within the body, resulting in steadily growing masses. In addition the cancer cells can spread either by active movement or more passively to other places in the body and there estabish new masses of cancer cells. Cancer cells have undergone a genetic transformation so that they have got these properties.
The cell masses are usually irregular lumps with diffuse boundaries, called malignant tumors, but more diffuse masses, or cells circulating in the blood also occur by some cancer types. Uncontrooled growth of cells without the ability to spread is not called cancer, but benign tumors. The reasons for cells transforming to cancer cells are many, like toxins, viruses, radioactive or ultraviolet exposure or sometimes pure coincidence.
There are many types of cancer and these are broadly divided in two classes. Carcinoma are cancers developed from epitelial cells or related calls, like glandular cells, immune cells, nerve cells and blood cells. Carcinomas mostly spread by the blood circulation, but can also spread on outer and inner surfaces, like the skin. Cancers originating in more inner cells, like those in connective tissue, bones or muscles are called sarcomas. These mostly spread by the lymph cystem.
Cancers also differs from each other by degree of maturity. The malignant cells can look much like normal mature cells with a specific function in the body, but they can also look like cells in developmnt. Even though malignant cells have properties of specific body cells, they will also look abnormal in many ways, and sometimes extremely deviant, with great and irregulrt cell kernels, for example.
Cancers differ according to malignacy, that is the ability to grow and spread. One usually measures the malignacy in grades fro 1 to four. Generally will unmature cancer cells with grossly deviant apearance be more malignat that mature cells that look much like normal cells.
A cancer case is usually also garded in 4 degrees according to how and how far it has spread. It can be a well borded lump within the tissue where it has originated. It can have spread further into adjacant tissues. It can have spread to lymph nodes, and it can have establshed new manifest tumors at other places.
Since cancer cells ar deviant, the immune system will recognize them and try to destroy them. Probably most beginning cancers are cleaned out by the immune system before they manifest themselvs by symptoms. Most cancers that develop further grow very slowly in the beginning, because the cells have not required the maximal malignancy yet, and because ithey are counteracted by the immune system, but eventually the disease accelerates.
