What is prostate cancer?

Prostate cancer forms when cells in the prostate gland grow abnormally, creating a tumour.

As you become older, your prostate can also grow for other reasons (not related to cancer), for example, benign prostatic hypertrophy (BHP). This condition is common in older males.

What are the symptoms of prostate cancer?

If you have prostate cancer, you may not notice any symptoms until the tumour grows to a certain size.

Some symptoms of prostate cancer include:

• needing to urinate (wee) more than two times at night, or frequently during the day
• needing to urinate suddenly
• difficulty with your urine stream — having trouble starting to urinate or a poor urine flow
• discomfort or pain when urinating
• blood or semen in your urine
• pain in your lower back, upper thighs or hips

Many people have these symptoms without having prostate cancer. If you notice any symptoms, it's important to check with your doctor.

What causes prostate cancer?

It isn't always clear what causes prostate cancer.

There are a number of factors that may increase your chance of getting prostate cancer, including:

• older age
• family history — it's more common if a close relative, such as your parent, sibling or child, was diagnosed with prostate cancer before 65 years of age
• changes to your genes — a very small number of prostate cancers are caused by a mutation in a gene called BRCA1 or BRCA2. These genes can increase the risk of prostate, breast and ovarian. If you have close relatives who have been diagnosed with these cancers, talk to your doctor about whether you should be tested.
• ethnicity — African males are more likely to get prostate cancer than Caucasian males and Caucasian males are more likely to get it than Asian males.
• living with obesity — obesity can increase your chance of having a type of prostate cancer that spreads quickly

When should I see my doctor?

See your doctor if you notice any changes when you urinate (wee). Changes in urination rarely mean you have cancer, but finding prostate cancer early improves your chance of treating it successfully.

If you don't have any symptoms, but are worried about your risk, see your doctor. They can give you information about whether prostate cancer screening is right for you.

How is prostate cancer diagnosed?

There are several tests your doctor may perform to check your prostate:

• Digital rectal examination (DRE) — your doctor gently puts a gloved finger into your rectum to check the size and condition of your prostate.
• Prostate specific antigen (PSA) test — a simple blood test to measure a protein produced by your prostate. A high PSA might be a sign of prostate cancer or another condition.
• MRI scan — a detailed imaging scan of your prostate that helps recognise signs of cancer.

If these tests suggest that you may have prostate cancer, a prostate biopsy can confirm the diagnosis. Your doctor will refer you to a urologist, who will take some cells from your prostate using a thin needle. These cells are checked under a microscope to look for signs of cancer.

Prostate cancer can be graded using scales such as the Gleason scale and the International Society of Urologic Pathology (ISUP) scale. These scales show how likely the cancer is to grow and spread to the rest of the body.

Should I have prostate cancer screening?

There is no nationwide prostate cancer screening program in Australia. If your doctor thinks it's right for you, routine PSA tests are often used to screen for prostate cancer.

Your doctor will not always recommend you have a PSA screening. There are several reasons for this:

• High PSA levels are not always caused by cancer.
• Experts don't fully agree on what is considered a normal or abnormal PSA level.
• Many prostate cancers are slow growing and have a low chance of being harmful if left untreated.
• Testing and treating low risk, slow growing cancers may cause more harm than good.

Speak to your doctor if you have symptoms or a family history of prostate cancer. Your doctor will discuss the pros and cons of having prostate cancer screening.

How is prostate cancer treated?

Treatment options for prostate cancer depend on:

• how likely the cancer is to grow and spread to other parts of your body
• the stage of the cancer — is it only in the prostate or has it already spread?
• your PSA level and how fast it's rising
• your age and general health
• potential side effects of treatment
• your personal preferences

Your doctor may discuss these options for treatment:

• watchful waiting — this means having regular checkups, without having treatment for your prostate cancer. This may be best for you if there is a low chance that the cancer will cause poor health. It helps you avoid possible side effects of treatment.
• radical prostatectomy — surgery to remove the prostate gland and some of the surrounding tissue. It can be an open procedure or may involve laparoscopy (a minimally invasive surgery).
• radiation therapy — uses low doses of radiation to treat the cancer. Radiation can be delivered from outside your body, known as external beam radiation therapy, or from an internal implant known as brachytherapy.
• hormone therapy — uses medicine to stop the production of the male hormone testosterone, which can stop the cancer growing. This is also known as androgen deprivation therapy (ADT).
• chemotherapy — anti-cancer medicines may be used if the cancer has spread to other parts of your body.

Each treatment has its benefits and risks. It's important to speak with your doctor or specialist if you have any questions or concerns about your surgery or treatment.

Living with prostate cancer

Being diagnosed with prostate cancer can be worrying. If you're feeling anxious about how prostate cancer might impact your life, talk to your doctor about getting support.

What are the complications of prostate cancer and its treatment?

Treatments for prostate can cause side effects and other complications. You might experience the following effects:

• erectile dysfunction — more than 3 in 4 men have trouble getting and keeping an erection after surgery, radiation therapy or ADT. There are effective treatments for erection problems that you can discuss with your doctor.
• poor bladder control — urine leakage, also known as urinary incontinence, can occur after prostate surgery or radiation therapy
• urinary and bowel problems — radiation therapy can cause your bladder and rectum to become inflamed (swollen and painful). You might have difficulty holding in your urine and need to get to a toilet quickly. You might notice blood in your urine or bowel motions.
• hormonal effects — ADT may reduce your sex drive or cause hot flushes, tiredness, sweating, hair loss, breast enlargement and muscle weakness. ADT can also increase your risk of developing osteoporosis, heart disease, diabetes and memory loss.

Can prostate cancer be prevented?

You may not be able to prevent prostate cancer, as you cannot change your age or genetics.

Having a healthy lifestyle may reduce your chance of having prostate cancer:

• Eat a healthy diet.
• Exercise regularly.
• Try to maintain a healthy weight.
• Do not smoke.
