Chiara De Biase from Prostate Cancer UK, who appeared alongside McFarlane on BBC Breakfast said the charity was also very disappointed.
“It has been three years in the making and we were actually the only organisation to submit the scientific evidence because we thought it was safe enough,” she said.
Ms De Biase said she felt “deep disappointment” for the black community, but said the charity had to be respectful of the science.
“We simply don’t have sufficient evidence, particularly for black men who have been woefully underrepresented in research,” she said.
The charity is funding a research trial called Transform, external which is looking to find the safest, most accurate and cost-effective way to screen men for prostate cancer.
McFarlane urged black men to sign up for the trial.
The trial is recruiting men aged 50-74, with a lower age limit of 45 for black men.
“If you’re between the age of 45 and 70, get hold of Prostate Cancer UK and go on their Transform programme to get this evidence that they say they’re missing,” the actor said.
He also urged GPs not to turn men away who asked for a PSA test.
“When a man is brave enough to come into your surgery, please don’t turn them away, please don’t say you’ve got no pain, you’ve got no symptoms …we don’t need to test you.
“I have no pain, I have no symptoms, but I do have prostate cancer. If you wait for pain and symptoms, it’s spread,” he said.
