Advantages and disadvantages of receiving cancer screening

I think I have a different frame of mind but also brings a number of benefits received by cancer screening, and was received on said remember that there are also disadvantages.
First is a merit. I think "early detection" is the biggest benefit. Case of cancer, such as lung cancer symptoms appear particularly difficult is very effective. Because almost no symptoms in the early stage is difficult to realize, it is likely that the situation will not be able to treat lung cancer. I can say that there is merit in the early treatment by having cancer found by screening these symptoms is difficult to come out. Early treatment also increases the likelihood of cure us and reduce the burden on the body. I think the benefits of cancer screening is also said to be to find a disease other than cancer to go further gastric cancer screening. Can lead to cure in less important thing to treat me as soon as possible is possible. It is a disadvantage of screening for cancer, but I can say with 100% safe and cancer screening up to no good. Ordinary people we might they think health should be said that there is no abnormality in cancer checkup, when you want there to where the cancer is difficult to see, you can have cancer types are different in checkup may or may not be found. There is a disadvantage to say to say that security is absolutely safe and can not be so. There is also a disadvantage to say there is also a burden like that inspection or examination painful to others. In cancer screening because there is advantages and disadvantages in this manner, we will continue to receive the like on the understanding it.
