I have a research paper i am doing on radiation therapy in breast cancer. Needs

I have a research paper i am doing on radiation therapy in breast cancer. Needs to have an introduction, four body paragraphs and a conclusion. The first couple of sentences in the intro need to talk about the case study. The third body paragraph needs to be on the case study. I have attached a document with some links that i used to find certain sources in the introduction and one of those links has a case study i choose. I will also send documents of how to write the introduction, body paragraph and conclusion the way the professor wants it. As many sources as you want but needs to have 11 direct quotes in total. I had someone writing the paper already so it is quite done but they did not follow the rules correctly and some of the body paragraphs are too short. They didnt add a case study in the intro or used my case study in the 3rd body paragraph so please fix it.
