Macmillan Cancer Support's chief medical officer Professor Jane Maher said the fact that we liver longer as a nation and the improvement of cancer treatment are "things to celebrate".
She added that there was, however, a "need to add a serious note of caution:"
Almost half the number of people in the UK will be diagnosed with cancer by the year 2020, a charity has warned.
Macmillan Cancer Support said the stark rise in the number of people who get, and survive, cancer poses a "herculean" challenge to the NHS.
The charity added that although almost one in two people are expected to get the disease, around four in 10 patients (38%) will not die from it.
The research was conducted from existing data on cancer prevalence, incidence and mortality, and found that the number of people who will develop cancer has increased by more than a third over the past two decades.
Cancer patients who work and those with children fork out an average monthly cost twice as high as those who are not in work or who do not have any children, a Macmillan spokeswoman has said.
Researchers at the University of Bristol surveyed 1,600 UK cancer patients to examine the impact on their finances during treatment. They found:
- Travelling to hospital appointments costs two in three patients £170 a month.
- Patients face an additional cost of £37 a month for parking charges at hospitals.
- A third said their fuel bills increased by about £24 a month.
- 30% said they were losing around £860 a month in earnings because they are unable to work or had to cut down their hours.
Cancer sufferers are forced to pay an average bill of £570 a month through their treatment, researchers have found.
Macmillan Cancer Support said four out of five patients face the "whopping" amount, which is comparable to a monthly mortgage payment.
Researchers at University of Bristol found the diagnosis of cancer often led to raised fuel bills, repeated travel costs for hospital appointments and a loss of income.

Mike Hobday, director of policy and research at Macmillan Cancer Support, has said that cancer patients are in a "dire" situation facing high energy costs combined with a lower income.
The cancer charity Macmillan has warned that around 27,000 cancer patients in the UK could be in debt as a result of falling behind on their energy bills.
A survey of 535 people who have been diagnosed with cancer in the last two years found that:
- 5% of respondents are currently in debt to their heating provider
- 54% are worried about the cost of heating their homes this winter
- 30% have had to turn off the heating in the last three months to save money
- 34% have put on outdoor clothes indoors to keep warm
