Because even with all we currently know, we still don't know enough about the genetic sequence or the way genes work to say "what gene or part of a gene is responsible for what" within a cell...with certain exceptions.
New breakthroughs in genetics don't always make the news, but we're learning more every day.

Well, they are working on learning how to do this as we speak, but the human physiology and genetics are very VERY complex mechanisms and actually getting it to work is easier said than done. And remember that the same defective DNA is in every cell in your body. How would they go about entering every cell and repairing it? There are some diseases where gene therapy may be helpful, and in your lifetime you may see the results of this therapy in one or two diseases (assuming you are young).

doctors can't fix abnormal/broken genes because it's in your dna and it would too small for them to see.

2 big problems
1) it is very hard to get new genes succesfully integrated in a cell
2) you got tons of cells

Ask those who prevent stem cell research
