Did you know almost 45,000 people are diagnosed with lung cancer every year in the UK? There are little or no symptoms in the early stages of the cancer forming. The signs to look out for are continuous coughing, breathlessness, coughing up blood, pains when breathing, weight loss and tiredness. Your GP suggests that if your cough continues for more than 3 weeks (with no improvement) you must book an appointment. If you have a concern about you or someone you know make sure you book an appointment with your doctor as catching it early is always best.
To reduce your chances of lung cancer stop smoking as smoking causes damage to the cells in your lungs. Watching what you eat; be careful of how much fatty foods you consume.
Exercising regularly can also help reduce the chances of developing lung cancer. Its suggested that adults do at least 2 and a half hours of exercise a week to keep fit and healthy.
