Aim: What happens if the rate of
mitosis is abnormal? Que sucede si la
mitosis es anormal?
What is the result of normal
Mitosis?
1 cell forms 2 identical NEW
healthy cells.
Mitosis produce dos celulas
identicas
What happens if mitosis stops?
Que pasa si se detiene la
mitosis?
• Aging/ Vejez
• Death/ Muerte
What is this? Que es esto?

Approximately 200 types
Lung
cancer
Skin

Prostate
cancer
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)
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.
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)
Metastasize/ 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.
Lung (Pulmon) Cancer:
Healthy Lung
Cancerous Lung
What causes cancer? Que causa cancer?
•Poor Diet/ Mala dieta
• Mutations - to genes, the
cell's instructions for
•Certain
Pathogens (Viruses)/
making the proteins it
Algunos
patogenos
needs to
survive, grow (viruses)
and multiply.
•Genetics/
Genes
• Ultraviolet radiation
• Viruses
•UV
Radiation (Sun)
• Usually cancer is not
inherited ultravioleta (UV) sol
Radiacion
• Carcinogens: chemicals
•Drugs (Tobacco)/ Drogas
(tabaco)
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.
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
Prevention/ Prevencion
• Don’t Smoke/ No fumar
• Wear Sunscreen/ Usar bloqueador
solar
• Regular check-ups/ Chequeos
medicos regulares
