Cancer may be malignant or benign. By way of the varieties of cells that form the tumor and by the trait features of those tumors, they are classified as carcinomas, sarcomas, lymphomas and leukemias. Several types of illustrative examinations are there to confirm, which types of disease a patient possesses. We will deal about these four types of tumor types one by one below.
Sarcomas: They will form only mostly in the connective tissues of the human body. Sarcoma has a special characteristic feature of spreading and invading any of the organ in the body. They generally occur in the blood vessels and lymphatic tubes, as they are formed by the connective tissues. Apart from these areas, sarcomas also form in the tissues of muscles, tissues of fibers, bones, bone cartilages, tissues of fat, and so on. The best examples of sarcomas are Ewing's sarcoma and Kaposi's sarcoma. These both types of tumors are of malignant sarcomas and are deadly in nature.
Carcinomas: These types of tumors mostly form in the tissues that contain epithelium. Skin in the body contains epithelium on it and covers the core organs of the body. These types of tumors are deadly and life-threatening neoplasm (new development) in nature. They commonly occur on the outer skin of the penis, urinary organs, around prostate glands, and ureters, core parts of the small intestines, and the interior part of the nose.
Leukemias: These tumors arise in the blood, especially in the white blood cells, and so they are called as leukemias or blood cancer. Blood originates in the bone marrow wherefrom blood passes to the other organs of the body through blood vessels. When leukemia tumor arises in the bone marrow, blood generates more white blood cells, and this abnormality is found when the blood test was done to the patient. These white blood cells are immature in nature.
Lymphomas: These types of tumors are also formed in the blood cells called lymphocytes on the lymph vessels and the glands of the lymphatic system. Lymph system is the autoimmune system of the body. These tumors commonly are life-threatening in nature.
Benign cancers are curable in nature; on the contrary to this malignant cancers are life-threatening and complicated in nature. Early detection and correct regimen of radiation, drugs, chemotherapy or hormonal therapy are essential needs of cancer disease. Many cancer treatments are costly. Cancer treatments are of two types, such as palliative and curative. Palliative treatments are given to the end-stage patients just to give them physical comfort and peace of mind. Curative measures are given to the patients with progressive and initial stages of disease.
