The day began at ASCO, a major oncology conference, where a clinical trial showing positive results from a cancer drug I helped to invent was presented.Coming from a family filled with cancer, I was elated to have struck a blow against the disease.

Just six hours later everything changed.

I awoke from a colonoscopy to hear these words: "He has colon cancer.  We'll schedule an emergency surgery immediately."

In a matter of seconds, at age 40, I transitioned from being a cancer drug discovery scientist to being a cancer survivor.

Ever since that moment, I have been both.

After an initial panic, the oncology scientist in me began to take control.  I decided.  "OK, this is a scientific problem.  I am a scientist and science is always advancing.  I will not assume I can't beat this." At that point I began to approach my cancer as the greatest research project of my entire life.

Initially I had performed academic oncology drug discovery – first at SUNY-Buffalo where I received a Ph.D. in medicinal chemistry (drug discovery) followed by a post-doctoral position at the Scripps Research Institute.  Following a research position at Millennium Pharmaceuticals, I have been a researcher at the Genomics Institute of the Novartis Research Foundation (GNF) since 2003.

More than two years after my initial cancer diagnosis, I received an additional diagnosis of Stage I melanoma in January 2015.

This had a big impact:  it blocked me from almost all colorectal cancer (CRC) clinical trials.  I was devastated – all of my research and planning had hinged on access to clinical trials.

My melanoma blocking me from clinical trials had turned into a scientific blessing. We are working hard to cure me, and to use my case to illustrate how to potentially cure others.  As a scientist, patient and advocate – this is thrilling beyond belief,  the most exciting science project I can imagine.

This is why I always describe myself as "currently incurable". This is a view I discuss frequently in my blog, "Adventures in Living Terminally Optimistic" written from the unique perspective of someone who is both a Stage IV cancer patient and a cancer scientist trying to help cure his own disease.

Will new scientific advances and our project save my life?  I firmly believe that most cases of advanced CRC will be cured within my wife's lifetime. I hope and am working hard to make it happen in my lifetime.
