Peter Andre's having to deal with the news he's been dreading: that brother Andrew's stage four cancer of the kidney and liver has spread to other parts of his body.
Pete's now keen to meet Prime Minister David Cameron to tackle cancer issues.
He's launching his own cancer foundation and is working with research organisations to find ways he can help.
A source tells Now's Dan Wootton: 'It's the fight of his life. He wants to find a cure.
'He'll leave no stone unturned.
'He supports the use of trial drugs passionately and wants to meet the PM to discuss ways to raise awareness.
'And he wants smoking to be banned altogether.'
Peter's also putting his energies into organising a ball to raise money for Cancer Research UK in September.
Last week, Rod Stewart agreed to help him.
