With the number of cancer patients in Wales set to double from 120,000 to 240,000 by 2030, cancer charities say the issue of isolation must be tackled 'immediately'.
It comes as a report by Macmillan reveals almost one in five people diagnosed with cancer here each year lack support from their family and friends.
This research shows that isolation can have a truly shattering impact on people living with cancer. Patients are going hungry, missing medical appointments and even deciding to reject treatment altogether which could be putting their lives at risk - all because of a lack of support.
