Cancer Research Glossary
Plain-language explanations of terms you'll encounter when reading about cancer research — from treatment types to trial statistics.
Treatments
Immunotherapy
Treatments that use the body's immune system to fight cancer.
Chemotherapy
Drugs that kill rapidly dividing cells, including cancer cells.
Targeted therapy
Drugs that block specific molecules that cancer cells need to grow.
CAR-T cell therapy
A type of immunotherapy that reprograms a patient's own T cells to attack cancer.
Hormone therapy
Treatments that reduce or block hormones that fuel certain cancers.
Chimeric antigen receptor (CAR) T-cell therapy
A type of immunotherapy that genetically engineers a patient's own T cells to recognise and destroy cancer cells.
PARP inhibitors
Drugs that block PARP enzymes, exploiting DNA repair defects in cancer cells such as those with BRCA mutations.
Genetics & biomarkers
Biomarker
A measurable biological signal used to detect disease or predict treatment response.
Gene mutation
A change in DNA sequence that can drive cancer development.
HER2
A protein that promotes cell growth — overexpressed in some breast and stomach cancers.
BRCA1 and BRCA2
Genes whose mutations significantly raise the risk of breast and ovarian cancers.
KRAS mutation
One of the most common cancer-driving mutations, found in lung, colon, and pancreatic cancers.
Clinical trials
Clinical trial
A research study that tests a medical intervention in human volunteers.
Trial phases (Phase 1, 2, 3)
The stages a new treatment must pass through before it can be approved for routine use.
Randomised controlled trial (RCT)
The gold-standard trial design, where participants are randomly assigned to treatment or control groups.
Statistics & evidence
Overall survival
The percentage of patients still alive after a set period — a key clinical trial endpoint.
Response rate
The proportion of patients whose cancer shrinks or disappears after treatment.
Meta-analysis
A statistical method that combines results from multiple studies for a stronger conclusion.
