Can my computer or monitor cause cancer?
Working by a computer and monitor has created worries for many people as to whether there were any health risks with long-term use and exposure. When looking at this, there are two pieces to this puzzle: the computer and the monitor.
When it comes to the computer itself (desktop computer or laptop), there have been many studies over the years to determine if there are any health risks. To some degree, there is a bit of radiation that a computer releases, but in quite small amounts (if any). Looking through many research studies, there does not appear to be any link between computer use and any increase in cancer risk. There have been specific studies regarding laptop use, when the laptop is sitting in the user's lap. Long-term use and exposure has been suspected as a possible cause of testicular cancer in males, but there has been no scientific proof to back up this suspicion or claim.
In terms of monitors, older CRT (cathode ray tube) monitors could emit X-ray radiation, but in small amounts. The small amount was not considered to be harmful to the human body. Newer LCD (liquid crystal display) and flat-panel monitors do not emit X-ray radiation. Some LCD monitors may emit a very small amount of UV radiation, but the amounts are so small that there is virtually no risk to the human body.
The biggest risk that computer usage poses is more directed at your eyes. Prolonged usage can cause eye strain and potential long-term issues. When using a computer, it is best to take periodic breaks, to allow your eyes to rest and stretch your body in general.
Something worth noting is that all electronic devices actually emit small amounts of radiation. The types of radiation will vary, but the important thing is that the amounts are very small. All around us there is radiation, but again in small amounts. The human body is capable of handling small amounts with little to no risk, which is what helps to make the human body so resilient.
