CANCER RECAP
• Uncontrolled cell growth that prevents healthy tissue from functioning correctly
What is cancer?
• Mutations of genes that control cell division and of genes that correct DNA replication errors
• p53 protein
What causes cancer?
• UV light, viruses, tobacco products, pollutants, radiation exposure, genetics
What causes these
mutations?

CANCER RECAPNormal
CellsRequire external growth factors to divide
Contact with other cells stops cell division
Age and die after a limited amount of times (usually 50)
Cancer Cells
Divide whether or not growth factors are present
Cells continue to grow after touching other cells
Cells divide infinitely

CANCER RECAP • Surgery for solid tumors
• Radiation kills cancer cells with high-energy rays that damage DNA to prevent replication – can also kill normal cells
• Chemotherapy drugs are toxic compounds that target rapidly growing cells by severely damaging DNA

CANCER RECAP • Minimizing exposure
to tobacco products, sunlight, and pollution
• Eating a diet with large amounts of colorful fruits and vegetables
• Vaccinations (Hepatitis B, human papillomavirus)
