Aye, though this would be from the point of view of "we have this awesome method we can apply to anything, let's try this understudied disease that people haven't made much headway on". Personally I'm interested in the general principles of cellular systems. Having some disease on the end of that is a nice way to give a project tangible benchmarks though. Had a minor bout of "that's unfair, those other guys didn't have to do all that", but it subsided... Oh and thundara you need to stop writing such long sentences no one can understand you seriously stop this is going on for way too long you need to understand punctuation should be used to punctuate things... MehCancer research is hard. Too many cooks in the kitchen, if you ask me. Everyone wants to be the one who "cures cancer", so everybody goes into cancer. Hence, NCI has one of the worst funding rates of any institute. Be afraid. Be very afraid.
As for the review, it won't be your last bad review. We try to make everyone else feel stupid, because it gives us catharsis for all the times other people have made us feel two feet tall. The trick is to not take it personal, even if you feel like it is.
NEVER write in long sentences when writing science. I had to learn that, as well. It's my natural tendency to write complex sentences with lots of embedded clauses and descriptors. The problem with this is that the majority of the people who will read your work are 1) not native English speakers, and 2) don't have a ton of interest in your language skills. Keep it concise and simple, and don't ever assume that the person who is reading what you wrote knows as much as you do about the subject matter. They don't.
