Getting To Know All about Cancer
Cancer is one of the most common deadly diseases to strike the human race. Cancer patients can come from every country of the world, they can be any age and either sex. There are a huge variety of different cancers that people can contract, but the basis of every cancer is the same on a cellular level.
Cancer is known the world over as a metabolic disease. A metabolic disease is a disease that is known to have an effect on the metabolic rate of the human body. The various forms of cancer affect different groups of cells within the body, for example lung cancer affects lung cells while leukaemia affects the bone marrow cells. However no matter which cells are affected, the various cancers all work in the same way.
Your entire body is made up of literally millions of cells each performing their own vitally important tasks. When cells are functioning normally they are created through other cells dividing, these new cells then live for a period of time divide and eventually die to be replaced by new cells again. Cancerous cells work slightly differently, they grow and divide faster and have a much longer life span. Cancerous cells do not follow the regular lifespan rules of normal cells, they divide much faster and live much longer, these cells then tend to form together into a solid mass which we know as a tumor.
Cancer cells are described as cells that have turned trophoblastic - this is a medical term that is used to describe a situation in which cells multiply at a faster than normal rate. Trophoblastic states can occur naturally in a healthy body for example when a injury occurs the rapid cell growth to heal the injury. Normal cells such as those that grow to repair an injury will normally stop growing or exit the trophoblastic state once the injury is repaired or the need for the accelerated growth is no longer necessary. The problem is that cancer cells remain in the trophoblastic state indefinitely, and so the cancer cells continue to divide and grow.
There are three main ways in which cancer cells can be treated or removed from the body, the first is by operating to remove all traces of the tumor. This procedure can be problematic as if all of the cancerous cells are not removed they will continue to grow and divide and so the cancerous tumour will redevelop. If the tumour has invaded an area of the body that cannot be operated upon or if the area is too large or too close to other vital cells surgical removal of the tumour may also be impossible. Chemotherapy and radiation therapy are the other means of treating cancer, both of these procedures are aimed at killing the cancer cells and thus preventing them from dividing further.
