I made sure to read all the previous comments here and the article kindly submitted to open the thread before posting this comment. I see the article links to a related website[1] with interactive advice on how to reduce risk of cancer, based on the study findings. That website has a page that sums up research has been showing for years, in multiple different studies:

"Research suggests that only 5 to 10% of cancers run in families. Some factors, like age, are outside our control, and some we just don’t know about yet.

"The really good news is that up to 45% of cancer in Alberta is caused by factors we can control.

"So while it’s not possible to completely prevent getting cancer, there are many proven things we can do to greatly reduce our risk. This is what cancer prevention is all about."

As I look at the site's advice, I see

Eat Healthy (I should still do a bit more to reduce calories while increasing dietary fiber from vegetables and whole grains, but I'm mostly on that already)

Prevent HPV Infections (I've got this covered)

Get Screened (some screening programs are useless, actually, but I participate in the screening programs with proven benefit)

Limit UV Rays (easy to do in Minnesota in the winter)

Live Tobacco-Free (I have always done that)

Be Active (I exercise moderately every day)

Maintain a Healthy Weight (I can improve on this a little)

Drink Less Alcohol (I go weeks at a time without drinking at all, and have never been drunk)

and control other risk factors, which I do.

You could do all of this too.
