I myself had a tumor removed from my large intestine when I was only 14. Cancer occurs when a single cell in your body acquires a set of random mutations in important genes that cause that cell to start to produce more and more and more copies of itself.
Rak se pojavljuje kada jedna, jedina stanica u vašem tijelu doživi set različitih mutacija u važnim genima koji potiču tu stanicu da proizvodi sve više i više vlastitih kopija.
