Can you explain the following? about the disease process of lung cancer

Cigarette use, exposure to carcinogens, such as tobacco smoke, also in environmental pollutants, such as asbestos, radon, and industrial chemicals, or genetic predisposition.
Induces genetic mutation in the DNA of lung cells, leading to initiation of the cancerous process.
Expansion of mutated cells.
Mutated cells begin to grow and divide uncontrollably forming abnormal cells known as tumors.
Tumors can be classified as small cell lung cancer (SCLC) or non-small cell lung cancer (NSCLC).
Tumor invades nearby tissues (Lung tissue, blood vessels, and lymph nodes.)
Cause structural damage.
Cancer cells break away from the primary tumor and travel through bloodstream or lymphatic system to the parts of the body. (Common sites of metastasis liver, bones, brain and lung tissues.
Tumor stimulates the formation of new blood vessels to supply it with nutrients and oxygen, supporting its continued growth.
Cancer cells can elude the body's defenses, thriving instead of being successfully attacked and eliminated.
Tumor grows and invades nearby structures. Patients may start experiencing symptoms of lung cancer.
