Cancer Suppressor Gene: The Cause Of Cancer

There are many possible causes, that can set off, trigger, or make cancer appear. By having abnormal gene functions, is one of the ways that helps contribute to the causing of cancer. The genes that everyone has, are all tiny little pieces of DNA (Deoxyribonucleic Acid). The instructions they give out basically help make the proteins we need to function, when it is time to destroy the damaged cells our body makes, and the last basic one is how to keep our cells in our body in balance. Three out of the many things genes control, is our hair color, eye color, and our height. It also helps affect whether you get cancer, and the chances of you getting it. Even though our cells have the same genes and chromosomes, different types of cells are use …show more content…
Typically, a person will have 2 copies of most of their genes. One from their mother, and one from their father. When a person inherits copies of a gene that are abnormal then they are already born with one mutation. If the copy that hasn’t inherited the abnormal gene stops working, the gene may stop working altogether. If the gene that stops working, is a cancer susceptibility gene then cancer may develop. Sometimes the cancer susceptibility gene can function as a tumor suppressor gene. Which means that A protective gene that normally limits the growth of tumors. When a tumor suppressor gene is mutated (altered), it may fail to keep a cancer from growing. BRCA1, an example of a tumor suppressor gene, was the first breast cancer gene to be identified; mutated forms of this gene are responsible for some cases of inherited breast cancer, especially those that occur in younger women. They are also a gene that are normal and that slow down cell division, they repair DNA mistakes, and tell cells when to die which is referred to apoptosis. When the tumor suppressor gene doesn’t work right, cells can grow out of control which can lead to cancer. Many of the families cancer syndromes are caused by inherited defects from the tumor suppressor …show more content…
Between 2003 and 2007, it has killed 792,495 lives, and it usually strikes between 55 and 65 years of age. Within the year of 2010, more than 157,000 are expected to die of the Lung and Bronchial cancer. In 2011, there was an estimated 402,326 people living with the Lung and Bronchial cancer. When someone has smoked or used tobacco products for a long period of time, they can get lung and bronchial cancer from this a lot easier than someone who has never used a tobacco product within their life. There are two types of this cancer, on is called Small Cell lung cancer, which spreads a lot quicker than the, Non-Small Cell lung cancer, which is the most common one. Small cell lung cancer is also called oat cell cancer. About 10%-15% of lung cancers are small cell lung cancers. This type of lung cancer tends to spread quickly. One way lung cancer can spread quickly is by the lymph system/nodes. Lymph nodes are small, bean-shaped collections of immune system cells (cells that fight infections) that are connected by lymphatic vessels. Non-Small cell lung cancer can start in the cells lining the bronchi and parts of the bronchioles or alveoli. Lung cancers are thought to start as areas of pre-cancerous changes in the lung. The first changes in the genes (DNA) inside the lung cells may cause the cells to grow faster. These cells may look a bit abnormal if seen under a microscope, but at this
