I have to again state the main goal of Cancer Quick Facts @ Solitarius.org is to provide a centralized hub of cancer research. With the risk of plagorism violations or copyright infringement…. which isn’t the case on the internet. My main goal is providing the visitant a compass for a direction without credit for the answer to cancer. Each time the visitant clicks onto a link externally and enters into anothers website thats giving them credit. So how can that be a violation or infringement on anyboby’s rights.
Often family members have certain risk factors in common, such as smoking which can cause many types of cancer. Abnormal genes that are passed along from generation to generation, that is often referred to as inherited cancer causing 5% to 10% of all cancers. Do impart only 5% to 10% of all cancers is caused by abnormal genes going array.
Which breaks down into inherited gene mutations or acquired (somatic) mutations. Genes seemingly, have two major roles in the development of cancer. Some that’s called oncogenes can cause cancer, others also known as tumor suppressor genes stop cancer from developing or growing.
Oncogenes, Tumor Supressor Genes and Cancer: oncogenes are mutated forms of certain normal genes of the cell called proto- oncogenes. Proto – oncogenes are often genes that normally control what kind of cell it is and how often it grows and divides. When a proto – oncogenes mutates (changes) into an oncogene, it turns on or activates when it is not supposed to be.
When this occurs the cell grows out of control while turning into cancer. A tumor suppressor gene is like the brake pedal of a car. It normally keeps the cell from dividing to quickly as a brake keeps the car from moving to fast. An important difference between the oncogenes and tumor suppressor genes. The oncogenes result from the activation of turning off the proto-oncogenes, however, the tumor suppressor genes causes cancer when they are inactivated (turned off.)
Even if you were born with healthy genes, some of them can become changed (mutated) over the course of your life. These mutations are known as sporadic or somatic, meaning they are not inherited. Sporadic mutations cause most cases of cancer. Those mutations ….may be caused by direct 0r indirect carcinogens that we are exposed to in our environment, including cigarette smoke, radiation, hormone imbalances, diet (although in many cases there is no obvious cause.)
Most genes mutations build up as we get older, leading to a higher risk of cancer. When someone has inherited an abnormal copy of a gene, their cells start out with one mutation. This makes it all the easier (and quicker for enough mutations to build up…. for a cell to become cancer. Although in a perfect world, if smokers wouldn’t smoke which causes 30% of all cancers and governments wouldn’t have to raise additional tax revenue from it; to pay off the cost of the health harzards from it.
