I come from totally engineering background but I'm passionate learner in my free time! I would like to start learning from the fundamentals about cancer and see if I can get some insights using my (engineering) background, as I'm progressing more and more in my learning career. Just give me your opinions and a real scientific roadmap I must follow, no matter how big it is (or how much it will take!), in order to understand cancer on some very serious level. It could be in form of a books (preferably), videos, forums, MOOCs, YouTube channels, scientific papers and all other resources you think are relevant, as long as it is serious as learning maths. Please put all that in, what you think is, a right order (from your experience), starting from very foundations. Thank you!
