The Irish Cancer Society has called on the Government to ensure that funding commitments for treatments and infrastructure improvements are met in full.
The call came at the organisation's annual survivors' conference in Galway.
Chief Executive of the society Averil Power said service enhancements in recent years had led to better outcomes for cancer patients.
But she said Ireland still lagged behind other countries in terms of the availability of certain medicines and that further steps are needed to meet the demand for treatment.
Ms Power said she hoped that all commitments in the National Development Plan, along with other investment pledges would be delivered in the forthcoming budget.
Today's conference sees over 300 people who have faced cancer gathering to discuss all aspects of dealing with and overcoming the condition.
It is estimated that almost 165,000 people are living with - or beyond - cancer in Ireland now.
Their experiences during and after treatment are central to the theme of the event: 'Living Well with Cancer'.
Delegates have heard about supports that are available during the course of medical care and there is a particular focus on the measures that can be taken to assist people living full lives after they finish treatment.
Among the topics being discussed are fatigue management, dealing with relationship issues, as well as the importance of mental and physical well being.
