Lung cancer is the leading cause of death from cancer worldwide, responsible for more than 1.7 million casualties each year. This insidious disease affects millions of people around the globe, with many not even knowing they are afflicted until it is too late. While there are a variety of types of lung cancer, the vast majority of cases are due to small cell and non-small cell carcinoma.

The most common form of this cancer is non-small cell lung cancer (NSCLC). It is the more treatable of the two types, as it often responds to targeted therapies and radiation. Unfortunately, even with these treatments, NSCLC is still often fatal. The earlier the diagnosis, the better chance of survival.

The other primary kind of lung cancer is small cell lung cancer (SCLC). This type is much more aggressive and is usually more difficult to treat as it is resistant to many of the common treatments. It often spreads quickly if not caught early and is highly fatal.

Diagnosing lung cancer can be difficult, as typically there are no symptoms in the early stages. Coughing, chest pain and difficulty breathing are common, though these can have various causes. Early detection is key, which is why regular screenings with doctors are essential for those at higher risk for lung cancer, such as those with a history of smoking.

Unfortunately, lung cancer does not have a cure. Treatment options vary from person to person, but typically involve surgery, radiation, chemotherapy and targeted therapies. Some individuals may be eligible for clinical trials as well.

For those living with lung cancer, self-care is of the utmost importance. Eating a balanced diet, exercising regularly, and getting adequate rest and relaxation can help the body fight off this deadly disease. It's also important to reach out for support, either through counseling, online support groups, or talking to friends and family.

Living with cancer is hard. Those who are afflicted face a difficult and often overwhelming battle. Fortunately, with better treatments and awareness, the rate of lung cancer deaths is decreasing. It's important to remember that with proper care and support, lung cancer sufferers can find hope and courage in their fight against this disease.
