Should i worry about lung cancer with radon? i've heard it can be in your house without knowing? we've rented ours for 10 years should i worry?

Radon : Radon is a bigger lung cancer risk if you smoke, so if you do, fix that first. Next, if you don't use your basement, don't worry. If you use your basement as a living space, check your radon level with both a short term and long term test kit from the local hardware store. If levels are high, its fixable, and not that expensive.

Risk factor: Radon is a risk factor for lung cancer. You can have your residence checked.
