How does the immune system fight cancer?

Complicated: Natural killer cells can recognize tumor cells and virally infected cells and destroy those. T-cells and antibodies to markers on tumor cells may also destroy tumor cells. Unfortunately, most of the time, some cancer cells evade this destruction and continue the disease process. The hope and potential of immune therapy remains to be realized.

Does the immune system protect against cancer too?

Yes: That's why people with compromised immune systems (such as HIV infection) are at higher risk for certain types of cancers.

Can all cancers weaken your immune system?

No: Liquid cancers of the blood (leukemia and lymphoma) can weaken the immune system and predispose a patient to infections. Other cancers only affect the overall immune system when they are very advanced and have spread throughout the bone marrow. It is true however, that all cancers have activated mechanisms in the body that shield them from the immune system and allow them to survive.

A 20-year-old female asked about a 43-year-old male:
Does having had cancer and being treated for it did it weaken your immune system?

That would depend on: the type of treatment. Having surgery would not necessarily weaken immune system - however chemotherapy might. Was there a specific type of treatment that you had in mind?

A 46-year-old member asked:
Does the cure for cancer lie in the immune system?

There will be no: Single cure for all cancers, but many fault immune system for inadequate detection of aberrant cells, called the "surveillance system". Those living with transplants are susceptible to higher risks of lymphoma and skin cancer, maybe others. Some immune modulators are used in prostate cancer. Intense, slow research effort here.
