The ones suffering the most are those who have children to take care and also have huge mortgages to pay.
Some of them are unable to work due to the condition. This results in loss of income. On an average 83% of victims incurred costs close to about £270 a month.
Attending hospital appointments and transportation proved quite costly. About 22% of the victims said that medicines were expensive.
Macmillan Cancer Support chief executive Ciaran Devane said: "This new research shows that cancer comes with a whopping price tag for many patients."
"Combined with the current recession and with welfare cuts, the cost of the disease is hitting the most vulnerable hardest. With the number of people living with cancer in the UK doubling from two to four million by 2030, this is a growing problem which cannot be ignored."
The charity is of the opinion that the government, NHS and business houses must come forward to help people with cancer.
