Video transcript

Hello, everyone and welcome to today's video. So which of the following is not a risk factor for developing skin cancer after repeated exposure to U V radiation. As answer choice A we have fair skin B history of sunburns, C family, history of skin cancer, D having blood type A B O. Let's begin by looking at a which states fur skin. Now for skin is going to put people at a higher risk for skin cancer because these condition causes the production of less melanin. Now, Melaine is going to be this pigment in our bodies that are going, that is going to protect us against U V radiation. If we are producing less Melaine, then we're going to have less protection against, against U V radiation and eventually skin cancer. Therefore, this will cause a person to have a higher risk of developing skin cancer and we're going to cancel it out. Then we have B we have a history of sunburns. Now, a history of, of sunburns is going to increase also the risk of skin cancer, especially when it happens in childhood or just adolescence. And therefore we're going to cancel it out. Then we have see family history of skin cancer. Now having a family history of skin cancer, especially certain types of melanoma can increase the risk of a person developing skin cancer due to genetics. And therefore, we're also going to cancel it out. And finally, we had the having blood type A B O. Now having a specific blood types such as A B O is not really associated with developing skin cancer. There is no effect or less protection or anything related to producing or increasing the risk of developing skin cancer that could be obtained or analyzed from the blood. And therefore, we're going to be highlighting answer choice D having blood type A B O as the final answer for our question. I really hope it's helped and I hope to see you on the next one.
