As many men as possible should turn up for a chat about prostate cancer, say organisers.
Expert Alvan Pope will be addressing the issue of the most common cancer in men in the UK.
More than 40,000 men are diagnosed every year, equal to more than 100 every day.
What many sufferers do not know is the disease can be managed, and over 250,000 men in the UK are living with and after prostate cancer.
According to The Hillingdon Hospitals NHS Foundation Trust, many say they are shocked when they first get diagnosed with cancer, and it is only later they think of things they wished they had asked the consultant.
Mr Pope is just such an expert. He is a consultant urologist at Hillingdon Hospital in Pield Heath Road, Hillingdon.
The meeting takes place on March 4 in committee room five of Hillingdon Civic Centre in Uxbridge High Street at 6pm, organised by the Trust.
Prostate cancer awareness has enjoyed a raised profile recently, thanks to the Men United camaign fronted by comedian Bill Bailey for the charity Prostate Cancer UK.
Terry Emerson of Harefield was diagnosed with prostate cancer three and a half years ago.
The 66-year-old of Harland Court is now urging all men to have a test that can help to catch prostate cancer in its early stages.
A prostate-specific antigen (PSA) test is a simple blood check which identifies signs of cancer.
“Wives and daughters need to drag men down to the doctor and ask for one,” said Mr Emerson.
"They have the power to save their lives, and nagging never killed anybody.”
