Hollywood actor Ben Stiller has revealed he was diagnosed with prostate cancer – but is now free of the disease after having surgery.

The star of Meet The Parents and Zoolander said doctors discovered a growing tumour, a mid-range aggressive cancer, in June 2014.

Writing on blogging site Medium, Stiller referenced cult show Breaking Bad, describing it as a classic Walter White moment.

The 50-year-old said he immediately started researching high-profile people who had been diagnosed.

Stiller wrote: As I learned more about my disease (one of the key learnings is not to Google ‘people who died of prostate cancer’ immediately after being diagnosed with prostate cancer), I was able to wrap my head around the fact that I was incredibly fortunate.

Fortunate because my cancer was detected early enough to treat.

The actor had an operation to remove the tumour and was declared cancer-free on 17 September, 2014.

He described it as a crazy roller coaster ride with which about 180,000 men a year in America can identify.

Stiller said the tumour was discovered and his life saved after he took a blood test known as a PSA test before the recommended age of 50.

If he had waited, Stiller believes the outcome could have been different.

Prostate cancer often grows slowly and may never cause problems, according to charity Prostate Cancer UK, but in some men it is more likely to spread, requiring urgent treatment.

There were more than 11,000 deaths from the cancer in the UK in 2014.
