Although it is a complex question to answer, scientists have identified a number of major factors that could contribute to the occurrence of cancer. Roughly 5 to 10 percent of cancers are hereditary. In other words, some people are born with certain genes having high tendency to cause cancer; it’s almost like that they are carrying a ticking bomb inherited from the parents. The rest, over 90%, are due to other controllable reasons, including tobacco, infections, radiation, chemicals, and extreme conditions that may cause mutation or damage of certain genes; if the gene mutation or damage is significant, the cells may have a better chance to become cancerous at some point in time. Therefore, avoiding these negative factors should greatly reduce the risk factors. This is why I believe it is highly possible to greatly reduce the chance of getting cancer for anyone.
Let’s think about how normal cells grow in layman’s terms. If normal cells are provided with sufficient and suitable nutrients and placed under appropriate environment, the cells should grow, function, divide, multiply, and die in a normal fashion designed by nature. However, if the growing condition of the cells is not “normal” so that certain genes in the cells are damaged/mutated and if the damage/mutation resulted in uncontrolled cell replication, normal cells could become cancer cells.
