Will we ever?

Have you ever wondered why we haven’t found a cure for cancer yet?  Well, the answer to that question lies in the fact that cancer may look the same on the outside, but each cancer actually develops in its own unique way, making it practically a different disease in every patient.  Scientists have found it extremely difficult to find one single cure, because the pathology of each cancer is very different.

So we might be asking the wrong question — there are countless cancers to be cured, not just one.

As scientists have developed numerous techniques and drugs over the years in the fight against cancer, it turns out that even the same type of cancer might behave very differently in two different patients. For example, one drug might be helping with the lung cancer in one patient, but it might have no effect on the lung cancer in another patient.

In this video by SciShow, Hank Green discusses the reasons why scientists have found it so difficult to find a cure for cancer. As Hank promisingly points out, new advances in genome sequencing are providing our best hope in the fight against the raging disease.
