Vaping is marketed as the healthy alternative to smoking. It's allegedly better for you because you're not inhaling a lungful of tar each time you smoke - that's the stuff that really gives you cancer, not nicotine.
Is it really the case that vaping is better for us than smoking? Not necessarily. It may not give you cancer (that we know about yet) but it still has health risks attached as shown in a recent study.
While we are all more than aware of the effects smoking has on our own health, as well as that of our loved ones, what you may not know is that passive smoking can also harm pets. So if you are planning to quit smoking as a New Year's resolution, and you are an animal lover, maybe this is the extra incentive you need to kick the habit forever.
Cancer is when a group of cells change and grow out of control. These cells form a mass called a tumour and begin to affect surrounding tissues. When this happens in the lungs, windpipe or main airways it's called lung cancer. If a cancer has spread to the lungs from a different part of the body it's referred to as secondary lung cancer.
Around 41,000 people in the UK are diagnosed with lung cancer every year - it's the second most common type. Although it's usually older folk who are diagnosed - the average age is 70-74 - younger people can develop it too.
