President Donald Trump is fit for duty - medically, mentally, cognitively, psychologically, emotionally, physically and otherwise.

Those in Hollywood are in a unique position to do tremendous good given their substantial platform. Unfortunately, with that megaphone comes immense responsibility.

Recently, I had the pleasure of filming a segment on the top medical, science and technology innovations of 2017 at Reuters TV in Times Square, New York with host of CCTV Bianca Chen (video clip forthcoming).

Norwegian researchers just reported that the anticoagulant drug warfarin may have another important health benefit in addition to its traditional role— reducing the risk of cancer.

Using a Twitter post, actress of Seinfeld and VEEP fame, Julia Louis-Dreyfus, announced she was recently diagnosed with breast cancer:

Yes, it's well-known that you can't make a horse drink if he or she doesn't want to, and apparently you can't get a man to stop taking a dangerous supplement — say one that produces cyanide when ingested — even when you tell him that it does so.

My heart sank when I received the news.

In the rich world, cancer therapy is expensive. In the developing world, it may not be available at all. Not only is cutting-edge technology in short supply, but so are things like electricity and medical personnel.

Imagine a world where it is as easy to check for cancer as it is high cholesterol. New research out of Johns Hopkins University School of Medicine may lead to just that.

Cancer is most easily "cured" when it's caught early. That's the rationale behind Pap tests for cervical cancer, PSA tests for prostate cancer, and mammograms for breast cancer.
