Working+Thesis

The advancement in cancer treatment and research would not be possible without the funding from companies and foundations.

Revised Thesis: With out companies and foundations like Vera Bradley, Sharpie, Wilson Binders, Susan G. Komen for the Cure, Alex's Lemonade Stand and LiveStrong providing grants and funding for cancer research and treatment other resources would not have been able to provide the results that are possible today.

Again, you have all of your ideas here, but let's work with the wording some. As is, it is too wordy. I don't think you need to provide such an extensive list of companies/foundations in your thesis statement. Which results are you referring to? Keep revising.
