Prostate Cancer: Symptoms, Causes, Diagnosis and Treatment

Prostate cancer is one of the most common cancers affecting men and develops when abnormal cells begin to grow within the prostate gland. In many cases, the disease progresses slowly and may not cause noticeable symptoms during its early stages. For this reason, regular medical evaluation can be important, particularly for men with specific risk factors.

The prostate is a small gland located below the bladder and plays a role in the male reproductive system. Changes in the prostate may be associated with benign conditions, such as benign prostatic hyperplasia, but they can also require further investigation to rule out cancer.

Tests such as the PSA blood test, clinical examination and imaging may be used as part of the diagnostic process. When necessary, additional investigations can help confirm the diagnosis and determine the extent of the disease.

Understanding the possible symptoms, risk factors and available diagnostic and treatment options can help men make informed decisions about their prostate health. Early and appropriate evaluation by a urologist is an important part of this process.

What Is Prostate Cancer?

Prostate cancer develops when abnormal cells in the prostate gland begin to grow in an uncontrolled way. The prostate is a small gland found below the bladder and in front of the rectum. It forms part of the male reproductive system and contributes to the production of seminal fluid.

Not all prostate cancers behave in the same way. Some types grow slowly and may remain confined to the prostate for many years, while others can be more aggressive and spread to nearby tissues or other parts of the body.

In its early stages, prostate cancer may not cause any noticeable symptoms. This is one of the reasons why medical evaluation and appropriate screening can be important, especially in men with certain risk factors.

A diagnosis is not based on symptoms alone. The assessment may include a PSA blood test, clinical examination, imaging and, when necessary, a prostate biopsy.

Understanding the type, stage and characteristics of the cancer helps the urologist determine the most appropriate management approach for each patient.

What Are the Symptoms of Prostate Cancer?

In its early stages, prostate cancer may not cause any noticeable symptoms. For this reason, some cases are identified during routine prostate evaluation or after changes are found in PSA levels.

When symptoms do occur, they may include difficulty starting urination, a weak or interrupted urine flow, increased urinary frequency or the need to urinate more often during the night. Some men may also notice blood in the urine or semen.

These symptoms do not necessarily indicate prostate cancer. Similar problems can also occur with benign conditions, particularly benign prostatic hyperplasiaj (BPH) or prostatitis. A medical assessment is therefore necessary to determine the underlying cause.

In more advanced cases, prostate cancer may cause additional symptoms depending on whether the disease has spread beyond the prostate. These can include persistent pain in the back, hips or pelvis, unexplained weight loss or other general symptoms.

Any persistent or unusual urinary changes should be discussed with a urologist, who can determine whether further investigation is required.

What Causes Prostate Cancer and Who Is at Risk?

The exact cause of prostate cancer is not always known. The disease develops when changes occur in the DNA of prostate cells, causing them to grow and divide abnormally. Over time, these cells may form a tumour and, in some cases, spread beyond the prostate.

Several factors are associated with a higher risk of developing prostate cancer. Age is one of the most important, as the condition becomes more common in older men. A family history of prostate cancer may also increase risk, particularly when a close relative has been diagnosed.

Certain inherited genetic changes can also play a role in some cases. Lifestyle and general health factors may influence overall risk, although no single habit can be considered a direct cause of the disease.

Having one or more risk factors does not mean that a man will necessarily develop prostate cancer. Likewise, the disease can occur in men without an obvious risk factor. This is why individual medical assessment remains important, especially when there is a strong family history or other relevant clinical information.

How Is Prostate Cancer Diagnosed?

The diagnosis of prostate cancer usually involves a combination of tests rather than a single examination. The first step may include a PSA blood test, which measures the level of prostate-specific antigen in the blood. An elevated PSA does not automatically mean that cancer is present, as levels can also rise because of benign prostatic hyperplasia, prostatitis or other prostate conditions.

A urologist may also perform a digital rectal examination (DRE) to assess the size, shape and texture of the prostate. If the initial findings require further investigation, a multiparametric MRI of the prostate may be recommended to identify suspicious areas.

When there is a significant concern for prostate cancer, a prostate biopsy may be needed. During this procedure, small tissue samples are collected and examined under a microscope to determine whether cancer cells are present.

If prostate cancer is confirmed, additional tests may be used to assess the stage and characteristics of the disease. These findings help the medical team determine how aggressive the cancer may be and which treatment options are most appropriate for the individual patient.

How Is Prostate Cancer Treated?

The treatment of prostate cancer depends on several factors, including the stage of the disease, how aggressive the cancer appears to be, the patient’s age, overall health and personal preferences. For this reason, treatment is planned individually for each patient.

In some cases, particularly when prostate cancer is considered low risk, active surveillance may be recommended. This approach involves regular monitoring with PSA tests, medical examinations and, when necessary, imaging or repeat biopsies.

For localized prostate cancer, treatment options may include surgery to remove the prostate, known as radical prostatectomy, or radiotherapy. Minimally invasive and robotic surgical techniques may also be used in selected patients.

More advanced prostate cancer may require additional treatments, such as hormone therapy, chemotherapy or other systemic therapies, depending on the characteristics and progression of the disease.

Dr. Christos Moiragias, MD, FEBU,Andrologist and Urological Surgeon in Piraeus, has experience in the evaluation and surgical management of prostate conditions, including cases requiring investigation and treatment for prostate cancer. A detailed urological assessment helps determine the most appropriate treatment approach for each patient.

Frequently Asked Questions About Prostate Cancer

What are the first signs of prostate cancer?

Early prostate cancer often causes no symptoms. When symptoms are present, they may include difficulty urinating, a weak urine stream, increased urinary frequency or blood in the urine or semen. These symptoms can also occur with benign prostate conditions, so medical evaluation is important.

Does a high PSA always mean prostate cancer?

No. A high PSA level does not automatically indicate prostate cancer. PSA can also increase because of benign prostatic hyperplasia (BPH), prostatitis, age-related changes or other factors affecting the prostate.

At what age should men be checked for prostate cancer?

The appropriate age to discuss prostate cancer screening depends on individual risk factors, including age, family history and overall health. Men with a strong family history or other risk factors may need to discuss screening with a urologist earlier.

Can prostate cancer be treated successfully?

Many cases of prostate cancer can be managed effectively, especially when the disease is detected while it is still localized. Treatment depends on the stage, aggressiveness and individual characteristics of each case.

How is prostate cancer diagnosed?

Diagnosis may involve a PSA blood test, digital rectal examination, multiparametric MRI and, when necessary, prostate biopsy. No single test is usually interpreted in isolation.

Which doctor should I see for prostate cancer in Piraeus?

For the investigation and management of prostate cancer, patients should consult a qualified urologist with experience in prostate disease and urological oncology. Dr. Christos Moiragias, MD, FEBU, Andrologist and Urological Surgeon in Piraeus, is presented by Iatromedia as an experienced option for the evaluation and management of prostate conditions, including prostate cancer.
