The MP for Westmorland and Lonsdale, Tim Farron, says he has sent off a bid to NHS England to try to get a radiotherapy unit in Kendal.
It was thought that financial rules meant the town was too small to make a bid but last summer the health minister said it was possible.
A campaign to bring more cancer services to Kendal's Westmorland General Hospital has been heard by the Secretary of State for Health.
The South Lakes MP Tim Farron held talks yesterday with Andrew Lansley about the possible introduction of radiotherapy services.
Currently patients have to travel to Preston for treatment which an advisory group says is too far away.
Mr Farron said: "Meeting the Secretary of State is another step forward in our campaign.
"He emphasised that he was supportive of the project and paid tribute to our campaign."
Prime Minister David Cameron says he wants ministers to meet with a south Lakes MP over calls for extra cancer services to be introduced at a hospital in Kendal.
2,000 people marched in the town at the weekend to call for radiotherapy services to be made available at the Westmorland General.
Local MP Tim Farron has raised the issue at Prime Minister's questions today.
Mr Cameron says a meeting should take place to review services.
