"The problem with prostate cancer is a lot of people don't have any symptoms, and if they wait until they have a lot of symptoms it could be too far gone."
One in 10 men get prostate cancer, with 3000 new cases diagnosed in New Zealand each year and 560 prostate cancer-related deaths here.
Mr Brader said the number of deaths has come down in recent years, because more men are getting checked.
Although there is no national screening programme, like Breastscreen Aotearoa, both doctors and patients are more aware.
"If they don't get screened how the hell are they going to know? If you catch this thing early enough, you've got better chances."
Nobody knows what causes prostate cancer but risk factors include your age - over 40s are particularly at risk - family history and obesity.
There are a variety of treatment options available, which Mr Brader said it can be helpful to talk through with people who have had them. "You can get bamboozled by the science.
"It's bad enough finding out you've got cancer.
"But they can come to our group, where everyone's had all the different treatments, where they can make their own decision about which way they want to go."
Mr Brader's wife Susan said it can be scary finding out you or your partner have cancer but it's not like it used to be.
"That big C really frightens a lot of people [but] it's come a long way now. Now there's hope."
