Hello, I am looking for someone to write an article on What Is Cancer. It needs to be at least 1500 words. Adenomas are cancers, which originate in the thyroid, the adrenal gland, the pituitary gland and other glandular tissues. Carcinomas are cancers that begin in the skin basal cells and in tissues covering internal organs. Central nervous system cancers start in the spinal cord and the brain tissues. Leukemia, cancer that causes the abnormal production of blood cells after it attacks the bone marrow where the production of these cells occurs (Crosta, 2010).

Every cancer begins in a cell, which is the basic unit of life. Normally, cells divide and multiply in the body in a fixed way to ensure its proper functioning. These cells also follow a natural death course after a particular period through a process called apoptosis. However, in the event of cell damage, the cell undergoes uncontrollable division and multiplication since it does not die. This stems from cell mutation, which is a permanent alteration in the cell DNA. Because of this damage, the DNA sends out wrong genetic instructions that cause cells to grow abnormally.

These damaged cells thus multiply and form a mass of tissues in an organ resulting in a tumor. The tumor may continue to grow and interfere with the body systems such as the digestive, circulatory and nervous systems. Moreover, the tumor may even release hormones that alter the normal functioning of the body. Tumors can be either benign or malignant. Benign tumors are not cancerous and remain on the organ where they form. On the other hand, malignant tumors, which are cancerous, are more dangerous since they not only attack one organ but also proceed to metastasize or spread to other body organs. After they invade and destroy a healthy tissue, they make new blood vessels to sustain themselves through a process called angiogenesis.
