Ex-government leader Sunak has reinforced his call for a specialized testing initiative for prostate cancer.
In a recent discussion, he declared being "certain of the critical importance" of implementing such a initiative that would be economical, achievable and "preserve innumerable lives".
His comments emerge as the National Screening Advisory Body reconsiders its ruling from the previous five-year period against recommending routine screening.
Media reports suggest the body may uphold its present viewpoint.
Champion athlete Chris Hoy, who has late-stage prostate cancer, supports middle-aged males to be screened.
He recommends decreasing the eligibility age for requesting a PSA blood test.
At present, it is not automatically provided to men without symptoms who are younger than fifty.
The PSA examination remains disputed however. Levels can increase for reasons other than cancer, such as infections, leading to false positives.
Skeptics argue this can lead to unnecessary treatment and side effects.
The suggested testing initiative would concentrate on males between 45 and 69 with a family history of prostate gland cancer and black men, who experience increased susceptibility.
This group comprises around 1.3 million men in the United Kingdom.
Charity estimates propose the system would require £25m a year - or about £18 per person per individual - similar to colorectal and mammary cancer screening.
The estimate includes twenty percent of eligible men would be notified each year, with a seventy-two percent response rate.
Clinical procedures (scans and tissue samples) would need to increase by twenty-three percent, with only a modest growth in medical workforce, according to the analysis.
Several healthcare professionals are uncertain about the benefit of examination.
They contend there is still a chance that men will be intervened for the cancer when it is not absolutely required and will then have to live with adverse outcomes such as incontinence and impotence.
One leading urological expert stated that "The challenge is we can often identify abnormalities that may not require to be treated and we risk inflicting harm...and my apprehension at the moment is that risk to reward ratio needs adjustment."
Patient voices are also shaping the debate.
One case features a 66-year-old who, after requesting a PSA test, was detected with the disease at the age of 59 and was informed it had spread to his pelvis.
He has since received chemotherapy, beam therapy and hormone treatment but remains incurable.
The patient advocates testing for those who are potentially vulnerable.
"This is very important to me because of my sons – they are 38 and 40 – I want them screened as promptly. If I had been tested at fifty I am certain I might not be in the circumstances I am today," he commented.
The Screening Advisory Body will have to assess the evidence and viewpoints.
While the recent study says the implications for personnel and availability of a testing initiative would be feasible, opposing voices have contended that it would redirect diagnostic capabilities away from patients being treated for alternative medical problems.
The continuing dialogue highlights the multifaceted balance between early detection and likely excessive intervention in prostate cancer management.
