I once waited to see my oncologist -- in a room with nothing more than outdated magazines and my own wandering mind -- for four hours. I offered up 20 hours of my time for chemotherapy treatments and then spent five days -- two times, for a total of ten days -- waiting in the hospital for doctors to determine how to raise my blood counts and decrease my fever after the completion of a dose-dense chemotherapy attack. I traveled to and from radiation appointments for 35 days, spending an average of 90 minutes on each of these round-trip excursions. I reclined in an infusion chair every three weeks for 12 months so that a new breast cancer wonder drug could sail through my veins. I spent 52 hours in that chair. And I spent countless hours pouring out my emotions to a counselor, in an attempt to clear my mind of all that cancer took from me -- including my time.

These are just seven memories I have of time lost to cancer. There are others -- countless others -- but this should suffice as proof that among all the potential side effects that accompany cancer, loss of time is a guarantee.

According to the first study to put a price tag on the time patients spend battling cancer, it seems the disease steals at least $2.3 billion worth of time for patients in the first year of treatment alone.

Eleven of the most common cancers were included in the study. And it was determined that 368 hours are lost during the first year of treatment for ovarian cancer. For lung cancer, 272 hours are lost. For kidney cancer, 193 hours go down the drain. These hours don't take into account time spent in bed recovering from surgery or chemotherapy treatments. It accounts only for time engaged in actively receiving care -- it counts chemotherapy, radiation, blood tests, scans, surgery, check-ups, waiting to see doctors, and driving to and from appointments.

The study, published in the Journal of the National Cancer Institute, sheds new light on the burden of commitment -- the human cost of cancer.

"Cancer is more than the just the dollars and cents for the medicines and the treatments and the doctors. It's also the lost opportunities for the patients," said the American Cancer Society's Dr. Len Lichtenfeld, of this overlooked reality.

Lichtenfeld says this study demonstrates the need for early detection. The earlier cancer is caught, the less time patients spend in the system. It also shows the need for more targeted therapies that spare patients physical side effects and allow them opportunities for taking pills at home instead of receiving treatment in clinics.

I would love to have back the time I spent treating and recovering from cancer. But I'm not heartbroken over my lost time. Because it bought me something in the end -- more time.
