Question

Skin cancer carries a lifetime risk nearly equal to that of all other cancers combined. Following is a graph [modified from K. H. Kraemer (1997). Proc. Natl. Acad. Sci. (USA) 94:11–14] depicting the age of onset of skin cancers in patients with or without XP, where the cumulative percentage of skin cancer is plotted against age. The non-XP curve is based on 29,757 cancers surveyed by the National Cancer Institute, and the curve representing those with XP is based on 63 skin cancers from the Xeroderma Pigmentosum Registry.

Explain why individuals with XP show such an early age of onset.

Accepted Answer

Hello everyone and welcome to today's video. So which of the following can be a symptom of scleroderma, pig Mentos um in Children and so were given certain symptoms that we need to select it from. But before we do that, let me quickly remind you of what this condition can cause. And it's basically a condition that makes it more difficult to repair cells after UV damage. So the UV damage is going to affect the DNA makeup of the cells and the cells are going to degrade normally. Our bodies can repair this but this, but the person that has this condition simply cannot do it as effectively. So they will have more extensive damage from just a few minutes of sun exposure. So let's go over answer choices. Knowing this answer choice A. We have severe sunburn after a few minutes of sun exposure. So something that would take a normal person hours to obtain this person with the condition listed is going to suffer after a few minutes. This sounds like it is a symptom so we're not going to cancel this out. Then we have answer to it is B and C. The appearance of records in sun exposed areas and dry skin after a few minutes of sun exposure is actually both going to be symptoms of the condition because like we said, it makes it more difficult to repair the cells. So the damage that sun exposure normally does is going to be more extensive and it's going to act faster on them. So because all of our answer choices are correct. We're going to select answer choice. The options are correct. As a final answer to our question. I really hope this video helped you, and I hope to see you on the next one.
