Is Prostate Screening Unnecessary?
Having concluded that screening does not save lives, the U.S. Preventive Services Task Force will recommend that healthy men forgo being screened with the familiar PSA blood test.
What's the Latest Development?
The U.S. Preventive Services Task Force is about to recommend that healthy men forgo being screened for prostate cancer with the familiar PSA blood test. Its recommendation is based on several human trials indicating that screening does not save lives. If a PSA level is high, for example, and the subsequent biopsy is positive for cancer, men who then receive treatment "do not have a lower death rate from prostate cancer than people who were never screened," says Marc Garnick, prostate cancer expert at Harvard's Medical School.
What's the Big Idea?
It is important to bear in mind that the Task Force's recommendation applies only to healthy men. Those with a history of prostate cancer in their family or African American men, who are at higher risk of contraction, should continue to be screened. "In the end, we urgently need a screening test that can distinguish well between prostate cancers that will become life-threatening and those that will not," says Garnick, "and we need treatments that come with fewer risks of severe side effects."

- Recent studies suggests that the keto diet might be an effective tool for treating depression, and clearing up so-called "brain fog," though scientists caution more research is necessary before it can be recommended as a treatment.
- Any experiments with the keto diet are best done in conjunction with a doctor, considering some people face problems when transitioning to the low-carb diet.
It's up to us humans to re-humanize our world. An economy that prioritizes growth and profits over humanity has led to digital platforms that "strip the topsoil" of human behavior, whole industries, and the planet, giving less and less back. And only we can save us.
