Catching cancer early is essential to fighting the disease after diagnosis.  

Emplify Health by Gundersen oncologist Dr. Kurt Oettel says there have been significant improvements in cancer treatments during his career.  

Dr. Oettel was a guest on La Crosse Talk with Sean Dwyer on Monday.  

The cancer specialist says environment, genetics and behavior are contributors to cancer, but there is seldom a single cause.  

What he says is clear is the value of screenings to treat the disease and save lives.
