Cancer begins when genetic changes allow cells to grow and survive outside normal controls. makes immunotherapy different from chemotherapy is shaped by patients, clinicians, hospitals and the prevention systems that determine when a problem is detected and treated.

The deeper explanation
The answer in detail
Chemotherapy directly attacks rapidly dividing cells. Immunotherapy instead helps the immune system recognise or attack cancer, producing durable responses for some patients but not every tumour.
Why it matters
Nearly every family is touched by cancer, and understanding its diversity explains why screening, prevention and treatment results vary so widely.
The public system around makes immunotherapy different from chemotherapy
Pharmaceutical incentives, diagnostic capacity and household income affect who receives effective care and how quickly evidence becomes practice.
The consequences reach public budgets and workplaces: prevention can reduce later costs, while unequal access shifts illness and lost work onto families and communities.
System lens
What makes this more complicated?
Three layers that help explain what changes the outcome.
Starting conditions
History, resources and institutional capacity set the starting position before the visible outcome appears.
Limits and trade-offs
Rules, capacity and competing priorities limit which responses are practical, even when several options look possible.
Choices and distribution
The outcome depends on who can change those conditions and how its consequences are shared.
