Mr Cocks and his Relay for Life team took part in last month's Moonee Valley event and raised $4860 for vital cancer research.

As a fanatical Essendon supporter it seemed appropriate for Mr Cocks to complete the relay at Windy Hill.

Team Brothers in Arms was started three years ago by Mr Cocks' brother Jeff.

"It was Jeff's idea and [he] got involved when I was diagnosed ... we've done it [taking part in relays] for the past three years and will continue to help raise funds," Mr Cocks said. The team's fundraising contributed to the $75,875 raised by the Moonee Valley event.

Mr Cocks was diagnosed with non-hodgkins lymphoma three years ago during routine surgery.

"I had been feeling unwell but was putting it down to working hard and a few different things. My youngest [child] was waking up early in the morning ... but I was putting it down to the wrong things, getting home at 9.30 each night, and I'd fall in a big heap."

Darryl and Jeff Cocks were joined by family and friends to complete the relay.

"Luckily, my brother is a detective and quite a few of his squad mates and former colleagues came along," Mr Cocks said.

The opening lap of the relay honours cancer survivors and carers. Mr Cocks was joined by his wife Maree and their children, Matthew, 18, Lauren, 15, and Erin, 7.

It is not too late for other Hume region residents to help raise funds for cancer research. Registrations close for the Hume Relay for Life at 5pm this Friday.

The event is on March 19-20 at The Meadows Greyhound Track, 80 Northcorp Boulevard, Broadmeadows.
