Stem Cells for Lung Cancer

Causes of Lung Cancer need Stem Cell

The exact cause of lung cancer is not fully known. Lung cancer develops when lung cells mutate in their DNA, causing uncontrolled growth and division. These abnormal cells accumulate to form tumors that can invade and spread to other parts of the body.

Smoking is the leading risk factor for lung cancer, accounting for the majority of cases. The harmful chemicals in tobacco smoke damage the DNA in lung cells, triggering mutations that lead to cancer. However, lung cancer can also occur in non-smokers, with risk factors such as exposure to secondhand smoke, radon gas, air pollution, and occupational hazards (like asbestos and certain chemicals) contributing to the disease. Genetic predispositions may also play a role in increasing susceptibility to lung cancer.

Treatment options for lung cancer depend on the type and stage of the disease. Common treatments include surgery to remove tumors, chemotherapy, and radiation therapy. In recent years, targeted therapies and immunotherapy have become increasingly important for treating certain types of lung cancer, particularly in patients with specific genetic mutations. These new treatments aim to boost the body's immune response or target cancer cells more precisely, improving outcomes for many patients.
