The wear it pink campaign has so far raised more than £23 million and the next event will be supported once again for the south.
The MP for South Basildon and East Thurrock has joined the fight against breast cancer by taking part in this year's campaign.
It is estimated to be the Breast Cancer Campaign's biggest fundraiser to help lifesaving research.
Mr Metcalfe commented:
“Every year in the UK around 50,000 women and around 400 men are diagnosed with breast cancer. Sadly 12,000 women and 80 men die from this disease. This is why we need to support Breast Cancer Campaign’s fundraising efforts so they can continue to fund research which will one day lead to a cure."
