Lung Cancer

Cancer cells create new blood vessels through a process called angiogenesis that sustain secondary tumor growth. The document discusses symptoms of lung cancer, which can include coughing, chest pain, breathing difficulties, and fluid in the lungs. It also lists symptoms of brain cancer such as headaches, dizziness, vision issues, and balance problems. The document then explains that factors like pollution, tobacco, asbestos, and certain occupations can precipitate lung cancer, while genetics, age, and gender can make one predisposed. It describes how carcinogens can damage DNA, cause abnormal cell growth, and lead to invasive lung carcinoma and metastasis through the lymphatic system and bloodstream.

Angiogenesis occurs Cancer Cells create new blood vessels that sustain secondary tumor growth

LUNGS

BRAIN

-nagging cough/persistent cough -chest pain -difficulty of breathing -productive cough/ nonproductive cough -crackles/ wheezing sound -presence of dullness on the affected side of the lungs -accumulation of fluid in the lining of the lungs (pleural effusion)

-severe head ache -dizziness -blurring of vision -difficulty in sleeping -problem in maintaining balance -fine motor incoordination ( finger to nose)

V.

PATHOPHYSIOLOGY

Precipitating factors: -environment (pollution) -tobacco use -other carcinogen (asbestos) -occupation (factory worker)

Cellular DNA mutation in tracheobronchial airways

Predisposing factors: -genetic -age (40 above)

Carcinogens binds and damages cells DNA Damage results in cellular changes Abnormal cell growth Malignant Cell DNA is passed on daughter cells Malignant Cells transformed to invasive lung carcinoma

-gender (male)

Malignant Cells will begin to metastasis

Lymphatic System Same process as the bloodstream Stock in the narrow channel of the lymph nodes

Blood Stream

Tumors cancer cell detach and pass through the walls of blood
