It can be confusing to meet someone who appears to have the same cancer but is receiving a different treatment. This does not necessarily mean that one plan is wrong. The name of a cancer is only the beginning of the information used to make a decision.
The cancer may not be biologically the same
Two cancers arising in the same organ can behave differently. Tests on a biopsy may show differences in cell type, grade, receptors, proteins or genetic changes. Some of these features predict whether a particular treatment is likely to help.
The useful tests depend on the cancer. Not every tumour needs every available molecular test.
Stage and location matter
Treatment for a small cancer confined to its original site may be very different from treatment for cancer that has reached lymph nodes or other organs.
Location can matter even within the same stage. A tumour close to a sensitive structure may require a different surgical or radiotherapy approach from one elsewhere.
The aim of treatment may differ
Treatment may be intended to cure cancer, reduce the chance of it returning, control it for as long as possible, or relieve a symptom. The same drug or radiotherapy technique can sometimes be used with different aims, doses or schedules.
Understanding the intended outcome helps make sense of the plan.
Health and previous treatment affect the options
Doctors consider kidney, liver, heart and lung function; other illnesses; medicines; mobility; frailty; allergies; and previous cancer treatment. An option that is appropriate for one person may carry more risk for another.
Age alone does not decide treatment. What matters is the person’s overall situation and the evidence for benefit and harm.
Personal priorities matter
There may be more than one reasonable option. People can place different weight on possible benefits, side effects, time in hospital, fertility, work, caring responsibilities or quality of life.
A good decision combines clinical evidence with informed preferences. It should not be based simply on copying another person’s treatment.
The plan can change over time
New scan results, side effects, response to treatment or changes in health can alter the balance. A treatment that was not suitable earlier may become relevant later, and the reverse can also happen.
Questions to ask
- What features of my cancer are guiding this recommendation?
- What is the aim of treatment?
- Were other options considered?
- Are any biomarker or molecular test results relevant?
- How do my health and priorities affect the choice?
- Will the plan be reviewed by a multidisciplinary team?
Another patient’s experience can be valuable for support, but it is not a reliable template for your own treatment. Ask your team to explain the factors that make your plan specific to you.
