What Should People Do If There Is a History of Prostate Cancer in Their Family?

A Guide to Genetic Risk, Early Diagnosis, and Proper Follow-Up

What Is Prostate Cancer and What Is Familial Risk?

Prostate cancer is one of the most common cancers in men. Not every case of prostate cancer is hereditary; however,the risk increases significantly in men with a family history of the disease.
A common question asked by the public is:
“My father / uncle / brother had prostate cancer—will I get it too?”

The answer to this questionmay be yes, but with proper monitoring and early diagnosis, prostate cancer is a diseasethat can be effectively managed in a high percentage of cases.

The point that Prof. Dr. Volkan İzolparticularly emphasizes in his clinical practice is this:
For men with a family history of the disease, the greatest dangeris delaying action.

How Much Does the Risk Increase If There Is a Family History of Prostate Cancer?

The risk of prostate cancer in the general population is approximately 10–12%.
However, a family history of the disease significantly increases this risk.

The increase in risk is as follows:

  • If a first-degree relative(father, brother) has prostate cancer → the riskincreases 2–3-fold
  • If two or more first-degree relativesare affected → the riskcan increase up to fivefold
  • If there is a history of prostate cancer at a young age (under 55) → the risk is even higher

📌 Patients with a family historyinvolving a father and a brother, in particular, are considered to be inthe high-risk group.

What Is Familial Prostate Cancer?

Familial prostate cancer is a condition in which prostate cancer occurs in more than one man within the same family.
This condition cannot always be explained by a clear genetic mutation; however, genetic predisposition, environmental factors, and shared lifestyle play a role together.

Some Factors Blamed on Genetics

  • BRCA2 mutation
  • HOXB13 gene variants
  • Defects in DNA repair genes

These genetic changes not only increase the risk of prostate cancer, but can also lead to cancerswith a more aggressive course.

When Should People with a Family History of Prostate Cancer Start Getting Screened?

This headingis one of the most critical points in the article.

General Rule:

  • Menwith nofamily history →age 50
  • Menwitha family history →aged 40–45

The inspection should begin.

Prof. Dr. Volkan İzol recommends that men with a first-degree relative who has had prostate cancer begin screenings“without waiting for symptoms to appear.”

What Checks Should Be Performed?

Follow-up for men with a family history of risk should beregular and systematic.

1️⃣ PSA (Prostate-Specific Antigen) Test

PSA is a protein that passes from prostate tissue into the bloodstream.

  • It does not, on its own, lead to a diagnosis
  • However,it is very valuable in risk assessment
  • The rateof PSAincrease over the years(PSA velocity) is particularly important

📌 In individuals with a family history, “normal PSA” levels are interpretedwith a lower tolerancethreshold.

2️⃣ Digital Rectal Exam

Although it’s an exam that many people are hesitant to undergo,it can save lives.

  • Prostate Firmness
  • Asymmetry
  • Presence of a nodule

is evaluated.

3️⃣ Multiparametric Prostate MRI

In recent years, it has been one of the most important tools for early diagnosis.

  • Shows suspicious areas
  • Prevents unnecessary biopsies
  • Enables targeted biopsy

The role of MRI is much more critical in patients with a family history of the condition.

4️⃣ Is a Prostate Biopsy Necessary?

A biopsy is not performed on every patient with a family history.

Decision on a biopsy:

  • PSA level
  • PSA growth rate
  • MRI findings
  • Examination Results

It is granted after being evaluated together.

In Prof. Dr. Volkan İzol’sapproach, a biopsyisnot a last resort, but rathera targeted diagnostic tool performed at the right time.

Is Prostate Cancer More Aggressive in People with a Family History of the Disease?

Unfortunately, yes, that's possible.

Familial prostate cancer:

  • It may appear at an earlier age
  • It could grow faster
  • It may take a more aggressive course

For this reason, the idea that “it’s moving slowly anyway”is wrong.

Are There Any Preventive Measures?

There is no method that can prevent prostate cancer 100%.
However, there are some factors that may help reduce the risk.

Lifestyle Tips

  • Maintaining a healthy weight
  • Regular exercise
  • Limiting red meat
  • A diet rich in vegetables and fiber
  • Cutting back on cigarettes and alcohol

These measures don't eliminate the risk, butthey do help.

The Biggest Mistakes for Those with a Family History of Prostate Cancer

  • To say, “My dad had it, but I’m fine”
  • Never getting a PSA test
  • Relying solely on the internet
  • Postponing inspections
  • Going to the doctor when you have a complaint

Early-stage prostate canceroften has no symptoms.

What Happens If Prostate Cancer Is Detected Early?

In prostate cancer detected at an early stage:

  • The success rate of the treatment is very high
  • Organ-preserving approaches are possible
  • Life expectancy and quality of life are preserved

For this reason, early detectionis the most powerful toolin the fight against prostate cancer.

The Psychological Aspect: Is a Constant Fear of Cancer Normal?

Men with a family history of prostate cancer:

  • Constant anxiety
  • The thought, “Will it happen to me, too?”
  • An excessive desire to get tested

can be seen.

The key here isto distinguish between information and fearand to develop the right follow-up plan.

Conclusion: People with a Family History of Prostate Cancer Should Not Panic, but Should Be Informed

Family historyis a significant risk factorfor prostate cancer, but itdoes not mean you are doomed.
With screening that begins at the right age, appropriate tests, and regular checkups, prostate cancercan be detected in its early stages and successfully treated.

The goal of the approach adopted by Prof. Dr. Volkan İzolis not to frighten the patient, butto educate them and bring the condition under control.
It should not be forgotten thatthe best treatment for prostate canceris early diagnosis.
