2 Aim: What happens if the rate of mitosis is abnormal? Que sucede si la mitosis es anormal?

3 What is the result of normal Mitosis? 1 cell forms 2 identical NEW healthy cells. Mitosis produce dos celulas identicas

4 What happens if mitosis stops? Que pasa si se detiene la mitosis? Aging/ Vejez Death/ Muerte

5 What is this ? Que es esto? Cancer

6 Approximately 200 types Can you think of some? Lung cancer Skin cancer Breast cancer Prostate cancer

7 What happens if cells are unable to regulate the cell cycle? Uncontrolled cell growth- abnormal cells continue to divide Si las celulas no pueden controlar el ciclo celular (Mitosis), continuan dividiendose creando tumores (cancer)

8 Cancer: Too many cells Abnormal Shape Abnormal function Starve the body’s other cells Cancer Demasiadas celulas Forma anormal Funcion anormal Utilizan los recursos de las celulas sanas.

9 Cancer Cancer: uncontrolled cell division Tumors -Lumps or a mass of cancerous cells. Tumors can be: malignant (spread - dangerous) or benign (can’t spread – safe) Cáncer: División de célula incontrolada tumores-masa de células cancerosas. Los tumores pueden ser: malignos (se riegan - peligroso) o benignos (no se riegan – seguro)

11 MetastasizeMetastasize/ Metastasis Cancer cells also can spread, to other parts of the body and form new tumors. How do they spread? They spread by using the circulatory system and lymph nodes. Las células cancerosas también pueden diseminarse a otras partes del cuerpo y formar tumores nuevos. ¿Cómo se propaga? Se propagan mediante el sistema circulatorio y los ganglios linfáticos.

13 Lung (Pulmon) Cancer: Healthy Lung Cancerous Lung

14 What causes cancer? Que causa cancer? Mutations - to genes, the cell's instructions for making the proteins it needs to survive, grow and multiply. Ultraviolet radiation Viruses Usually cancer is not inherited Carcinogens: chemicals Poor Diet/ Mala dieta Certain Pathogens (Viruses)/ Algunos patogenos (viruses) Genetics/ Genes UV Radiation (Sun) Radiacion ultravioleta (UV) sol Drugs (Tobacco)/ Drogas (tabaco)

17 Cigarette/ Cigarrillos Smoking causes a third of all cases of cancer Cigarette smoke contains 3000 different chemicals. Fumar causa un tercio de los casos de cáncer. El humo del cigarrillo contiene 3000 productos químicos diferentes.

18 Treatment/ Tratamiento Surgery: physical removal of the malignant tumor Radiation: disrupts cell division Chemotherapy: drugs that prevent cell division by interfering with mitosis Cirugía: cortar el tumor maligno Radiación: interrumpe la división celular Quimioterapia: medicamentos que impiden la división celular interfiriendo con la mitosis
