Question

although contracting melanoma as a child or teenager is extremely unlikely, skin cancer experts estimate that about two - thirds of a persons risk of melanoma is acquired in the first 18 years of life. this is because young people typically have much higher rates of sun exposure through their activities (swimming, playing sports, etc.) than adults. reducing sun exposure during childhood and adolescence, even just by using sunscreen, could decrease an individuals lifetime risk of developing skin cancer by up to 78 percent.
in a recent study, researchers found that teens had a good understanding about the connection between sun exposure and cancer. despite this knowledge, just 25 percent of 14 - year - olds reported using sunscreen \always\ or \almost always.\ older teens were even less likely to use sunscreen, and spent more time on average in the sun.
what information about sun exposure and cancer risk can sarah use in her editorial? check all that apply.
teens seem to understand that the sun can cause cancer, but they often fail to protect themselves.
teens do not need to use sunscreen as often as adults, because they have little cancer risk at their age.
sunscreen is more important for adults than for teens and younger children.
most teenagers do not realize that sun exposure can lead to cancer.
most lifetime melanoma risk comes from sun exposure when people are young, but teens are less likely to use sunscreen during this time.

Explanation:

• The first option is correct as the text mentions teens understand the sun - cancer connection but don't protect themselves (only 25% of 14 - year - olds use sunscreen "always" or "almost always" and older teens are less likely).
• The second option is incorrect because the text says reducing sun exposure (including using sunscreen) during childhood and adolescence can decrease cancer risk, implying teens should use sunscreen.
• The third option is incorrect as the text emphasizes the importance of sun protection (including sunscreen) during childhood and adolescence for lifetime cancer risk.
• The fourth option is incorrect as the text states teens have a good understanding of the sun - cancer connection.
• The fifth option is correct as it aligns with the text that two - thirds of melanoma risk is acquired in the first 18 years (young age sun exposure) and teens are less likely to use sunscreen.

Answer:

Teens seem to understand that the sun can cause cancer, but they often fail to protect themselves. ; Most lifetime melanoma risk comes from sun exposure when people are young, but teens are less likely to use sunscreen during this time.
