Discuss the two main causes of skin cancer.
Answers will vary but should relate to exposure to solar radiation and artificial sources. The greater the intensity and time of exposure, the greater the chances of developing skin cancer. Melanoma risks are greater from high-intensity exposure when you are young. Squamous cell carcinoma and basal cell carcinoma risks are greater with cumulative lifetime exposure.
What are possible risk factors that increase an individual's chance of developing cancer?
Tobacco, sunlight, ionizing radiation, some chemicals, some viruses and bacteria, some hormones, genetic predisposition, poor diet, and lack of exercise are all possible risk factors for cancer.
Explain how you can decrease the risk of developing smoking-related cancers.
Decrease the amount of smoke to which you are exposed over time.
Describe five possible treatments for cancer.
Radiation involves irradiating cancer cells. Chemotherapy uses drugs to kill cancer cells or interfere with their reproduction. Surgery removes tumors and sometimes the surrounding tissue. Immunotherapy uses vaccines and medicines to boost the immune system to attack cancer cells. Hormone therapy blocks production of hormones and treats cancer cells so they do not respond to hormones, possibly by removing hormone-producing glands.
