WASHINGTON (TNND) — Cancer has surpassed heart disease as the leading cause of death for many high-income countries, including France, Italy, and the U.K.

That’s according to a recent study published in The Lancet, which is a weekly peer-reviewed medical journal.

Dr. Yusuf Saleeby is an IMA senior fellow and expert in functional and integrative medicine specializing in innovative approaches to cancer prescreening. He said it’s important for people to understand that cancer screenings aren’t a “one-size fits all” process as mainstream medicine tends to be.

I think the most important thing to realize is why you want to do it and how you want to do it,” he told The National News Desk’s Jan Jeffcoat Wednesday during a one-on-one interview.

Jeffcoat asked how Saleeby tailors cancer screening recommendations for patients who are high-risk but want to avoid unnecessary radiation or invasive procedures.

It could begin very personalized,” he said. “You do a very good history and physical exam. You do an inventory of social and family history, and then you use select biomarkers like vitamin D levels (and) home assisting levels. You look at certain biomarkers of inflammation. This will all raise the risk of certain cancers, so that’s a starting point.”

Saleeby added that he has seen more incidences of bad outcomes with cancer, as well as infectious diseases and autoimmune diseases, in patients who lack vitamin D.

Vitamin D augmentation is one of the standard processes of cancer therapies in the alternative realm,” he said.
