What do survival rates actually mean for your diagnosis?

The five-year relative survival rate compares the proportion of people with a specific cancer who are alive five years after diagnosis to the proportion expected to be alive in the general population of the same age, sex, and race. A rate of 99% does not mean 1% of patients die from the cancer. It means the diagnosed group's survival is 99% of what would be expected without the cancer. It is always a backward-looking population statistic. Source: NCI SEER Program, seer.cancer.gov.

Cancer stage describes how far the disease has spread at diagnosis. Localised means confined to the organ of origin. Regional means it has spread to nearby lymph nodes. Distant (metastatic) means it has reached other parts of the body. Survival rates differ dramatically because localised cancers are generally more treatable with surgery, radiation, or targeted therapy. For example, localised lung cancer has a 64% five-year survival rate compared to just 9% for distant-stage lung cancer. Source: NCI SEER 2014-2020.

No. Survival rates are population-level statistics, not individual predictions. They describe what happened to large groups of people diagnosed in previous years. Your individual outcome depends on many factors: tumour biology, genetic markers, treatment response, overall fitness, comorbidities, and access to care. Two people with the same cancer type and stage can have very different outcomes. These numbers provide context for informed conversations with your oncologist, not a forecast.

Three factors drive this. First, the pancreas sits deep in the abdomen with no reliable screening test, so most cases are diagnosed at the distant stage when surgery is no longer possible. Second, pancreatic tumours are biologically aggressive and resistant to many standard chemotherapy regimens. Third, symptoms like back pain, weight loss, and jaundice often mimic other conditions, delaying diagnosis. Localised pancreatic cancer has a 44% five-year survival rate, underscoring how much early detection matters. Source: NCI SEER; American Cancer Society.

Modern cardiac surgery has become remarkably safe. Isolated coronary artery bypass grafting (CABG) carries an in-hospital mortality rate of approximately 1-2% according to the STS National Database. Aortic valve replacement runs 2-3.5%, and combined procedures are higher at 3.5-6%. These are national averages. Individual risk depends heavily on age, emergency status, ejection fraction, kidney function, and whether the surgery is a first operation or a reoperation. High-volume surgical centres consistently outperform low-volume ones. Source: STS Adult Cardiac Surgery Database.

Yes, significantly. In-hospital sepsis mortality rises steeply with age. Adults aged 18-44 have a mortality rate of roughly 6-8%, while those aged 85 and older face 40-50% mortality. This gradient reflects declining immune resilience and higher burden of chronic conditions in older adults. Speed of recognition and treatment is the single most important modifiable factor: each hour of delay in antibiotic administration increases mortality measurably.

Yes, though the gap has narrowed considerably over the past two decades. For most common cancers, US five-year survival rates are modestly higher than UK rates. Contributing factors include earlier average stage at diagnosis in the US, faster access to newer treatments, and differences in data collection methodology. The UK has invested heavily in early diagnosis initiatives, and for cancers like breast and melanoma, UK survival now approaches US levels.

The NCI SEER Program publishes updated survival statistics annually, typically in the spring via the SEER Cancer Statistics Review. Each update incorporates the most recent year of complete follow-up data. Because five-year survival requires five years of observation, the latest statistics always reflect diagnoses from several years prior. Cancer Research UK updates its statistics annually based on Office for National Statistics data. This calculator is refreshed within 30 days of each major data release.
