Tooraweenah resident Brian Mockler has become a strong advocate for ovarian cancer awareness after his wife died from the disease in 2014.

The overall five-year survival rate for women diagnosed with ovarian cancer is 43 per cent, largely due to symptoms going undiagnosed.

In August 2010 Brian's wife Margaret went to visit her GP over an increasing "whispyness" in her voice. From there she was sent to Dubbo for a chest X-ray.

"The radiologist immediately contacted our GP and a CT scan was urgently undertaken followed by draining almost two litres of fluid from Margaret through a chest drain tube," Mr Mockler said.

"It was an extremely unpleasant experience. [The doctor] said to her 'you don't muck around when you are dealing with something serious'."

The tests were done on the Friday, on the Monday Margaret was diagnosed with ovarian cancer.

"Unknown to us, lurking in the background Margaret was experiencing unrecognised symptoms which were to have a devastating effect," Mr Mockler said.

"Over a period of months Margaret experienced occasional symptoms of abdominal and internal pelvic discomfort, but nothing felt out of the ordinary. At meal time Margaret felt full easily but not bloated."

Mr Mockler said it was the mission of Margaret's two daughters, two sons and himself to promote ovarian cancer awareness in her memory.

"We urge women and their husbands/partners to be vigilant with becoming aware of potential symptoms and to have them medically investigated at the earliest opportunity. While very difficult, it is possible and can change lives."

The most commonly reported symptoms for ovarian cancer are abdominal or pelvic pain, persistent abdominal bloating, the need to urinate often or feeling full after a small amount.

Money raised through the teal ribbons allows Ovarian Cancer Australia to develop and expand awareness, support and research programs.
