Prostate Cancer Checks at 1 Health: What You Need to Know

Why prostate checks matter

Prostate cancer is the most common cancer in Kiwi men. The good news is that many men diagnosed early do very well. The tricky part? Not every prostate cancer needs treatment, and tests aren’t perfect. That’s why it’s important to sit down with your GP, talk through the options, and make the decision that feels right for you.

At 1 Health (Henry Wigram Drive, Christchurch), we offer both the PSA blood test and the digital rectal exam (DRE). More importantly, we’ll guide you through the pros and cons in a clear, supportive way.

The two main checks

PSA blood test

A simple blood test that measures a protein made by the prostate.

✅ Can sometimes pick up cancers before symptoms show.
⚠️ Levels can also go up for other reasons (infection, benign enlargement, recent activity), which can cause false alarms.

Digital rectal exam (DRE)

A quick exam where the doctor gently checks the prostate with a gloved finger.

✅ Helps detect suspicious lumps or changes.
⚠️ On its own, it doesn’t pick up every cancer, so it usually works best alongside PSA

The debate: to test or not to test?

Over the years, big studies around the world have shown mixed results. Some found that regular PSA checks lowered the chance of dying from prostate cancer. Others showed little or no difference.

The main issue? Overdiagnosis. Some prostate cancers grow so slowly they never cause problems. But once found, they can lead to extra scans, biopsies, or even treatments that aren’t always needed.

That’s why most guidelines now agree: the decision should be made together with your doctor, based on your age, risk factors, and preferences.

What the guidelines say

In New Zealand, there’s no national screening programme. Men aged 50–70 are encouraged to talk with their GP. If you’re Māori, Pacific, or have a strong family history, it’s worth considering testing earlier (from age 40).

In the US and Europe, guidelines recommend the same shared approach—especially between 55–69. Above 70, routine testing isn’t usually advised.

If your PSA is raised

Don’t panic—many men with a slightly raised PSA don’t have cancer.

What usually happens next:

Repeat the test in a few weeks.
Look at risk factors (age, family history, symptoms).
Arrange a prostate MRI before any biopsy (now common practice).
Biopsy only if needed, and in safer, more targeted ways than in the past.

Should you consider testing?

You may want to talk to us if:

You’re between 50 and 70.
You’re 40+ with a strong family history of prostate cancer.
You’re Māori or Pacific, as risks are higher.
You have urinary symptoms (frequent peeing, weak flow, blood in urine).

Why you grind your teeth at night and how to stop it

30 September 2025

Have you been waking with a sore jaw? Experiencing unexplained headaches, or teeth that look more worn than you remember? If so, you might be experiencing night-time teeth grinding. Known medically as bruxism, this condition is surprisingly common. For some people it’s occasional, while for others it becomes a nightly habit with serious consequences. At 1 Health Christchurch, we see patients every week who had no idea they were grinding until the signs became impossible to ignore. With the right dental care, bruxism can be managed effectively, and often with a simple, comfortable dental solution. What is bruxism? Bruxism is the involuntary clenching, grinding, or gnashing of teeth , most often occurring during sleep. Because it happens subconsciously, many people don’t realise they grind until they notice the after-effects: tooth wear, jaw tension, or being told by a partner that their grinding is keeping them awake. There are two forms of bruxism. Awake bruxism is usually linked to stress or deep concentration, while sleep bruxism is classified as a sleep-related movement disorder. Both cause the same long-term damage to teeth and jaw joints. How do I know if I’m grinding my teeth at night? Bruxism shows itself in a variety of ways. Some are obvious dental issues; others are more general health complaints you may not immediately connect to your teeth. If the following symptoms of bruxism are relatable, it’s worth arranging a consultation at our dental clinic in Christchurch to investigate further.

Worried about your skin? When to book a skin cancer check in Christchurch

30 September 2025

Skin cancer is the most common cancer in Aotearoa New Zealand, estimated to account for about 80% of all new cancers diagnosed in the country each year. Yet despite this, many people delay or skip regular skin cancer checks, sometimes until it’s too late. The reality is that most skin cancers can be successfully treated if caught early. Understanding when and how to book a skin cancer check in Christchurch is crucial for early detection. Despite our high risk of skin cancer, many people delay or avoid booking a skin cancer check. Some of the most common reasons include: I don’t have time. Life is busy, and health checks can fall to the bottom of the to-do list. I don’t want to waste the doctor’s time. Many people worry they’ll book an appointment only to be told it’s ‘just a mole.’ But 1 Health GPs in Christchurch would much rather confirm it’s harmless than risk missing something serious. I don’t know what to look for. Self-checking can feel confusing if you’re unsure what’s normal. That’s exactly why professional checks exist, your doctor knows the warning signs. It’s probably nothing. This is one of the most dangerous assumptions. Skin cancers often start small and seemingly harmless, but they can change quickly. No referral is necessary to see the team at 1 Health, we’ve consciously designed our skin check service to be convenient and accessible , with weekend appointments available and flexible payment options such as Afterpay. A thorough skin check with a dermatoscope takes just 30 minutes, making it easy to fit into your day, even during a lunch break. It’s a small investment of time that could save your life.
