Write 2-3 sentences for each question. What is cancer? Hint: In what way could it involve the cell cycle? How can we consider cancer a genetic disease? What factors affect the likelihood of developing cancer? How is cancer fought and treated?

What is cancer? Hint: In what way could it involve the cell cycle?

Contact inhibition fails to limit growth in cancerous cells. Normally, cells in a petri dish will growth until limited by space: Contact inhibition fails to limit growth in cancerous cells.

Various Stages of Development In situ – it is localized and has not invaded surrounding tissues. Malignant or invasive cancers have spread through various means to surrounding tissues and deprive them of nutrients, thus harming tissues. Mutation proliferation survival/invasion metastasis ONCOGENES – causes cancerous growth

Tumor A Tumor B Describe (2-3 sentences) how tumor A and its surrounding blood vessels is different from tumor B. What might these differences suggest?

How can we consider cancer a genetic disease?

What factors affect the likelihood of developing cancer? Radiation therapy Powerlines Atomic blasts Computer screens Nuclear power plants Lightbulbs Radar guns Radon found in indoor air Cell Phones Mircrowaves Radon found in outdoor air Nutrasweet (Aspartame) Food irradiation High fat diet UV Obesity Electric blankets TV

How is cancer fought and treated? Surgery Radiation Chemotherapy Anti-angiogenic drugs Anti-metastatic drugs How is cancer fought and treated?

Clinical Trails Stage I Stage II Stage III Reasons for trails: treatment options identification and diagnosis Prevention management of symptoms Management of treatment side effects Stage I: to find a safe dosage, how to administer the dosage, and how it affects the body Stage II: to explore how the treatment effects a certain cancer, further see how it affects the body Stage III: explore how the treatment compares to current treatments for cancer Clinical Trails
