Was there disease before Adam sinned?

Many Christians and even Christian leaders, have accepted the evolutionists' teaching of millions of years when it comes to the fossil record. When believing this many don't take into account that they are also accepting that horrible diseases were rampant before sin.
There's a special branch of science called paleopathology. This branch studies diseases in fossils. For example, dinosaur bones that are supposedly millions of years old show evidence of arthritis, abscesses, and osteoarthritis. Many fossil bones have also shown evidences of cancer and other diseases.
So, by a Christian believing that the fossil record was laid down millions of years before Adam and Eve, then they also have to accept that there were all sorts of horrible diseases in the world before sin. But how could God have described such a world as VERY GOOD?
Many of the diseases found in fossil bones are the exact same kinds of diseases that also affect humans.
No, our answers from the book of Genesis make it clear that there were NO diseases or death before sin. This is just one more reason why Christians cannot believe in the millions of years theory to form the fossil record.
