They can metastasize to other parts of the body
They are always benign
What is tumorigenesis?
The immune response to tumor cells

Which risk factor is associated with the development of tumors?
Smoking tobacco products
Regular exercise
Low fruit and vegetable intake
High physical activity
What are tumor-associated antigens (TAA)?
Antigens found only on healthy cells
Antigens that suppress immune responses

Antigens expressed on healthy cells but elevated on tumor cells
What is the role of dendritic cells in anti-tumor immunity?
To directly kill tumor cells
To present antigens to T cells
To suppress immune responses
To produce antibodies
Which immune cells are primarily involved in the elimination phase of tumor immunity?
B cells
Macrophages
T helper cells
Neutrophils
What is the function of immune checkpoint inhibitors in cancer treatment?
To enhance tumor growth
To block immune responses
To stimulate immune responses against cancer cells
To prevent T cell activation
What is the tumor microenvironment (TME)?
The area surrounding healthy cells
The immune cells that attack tumors
The blood supply to tumors
The unique ecosystem surrounding tumor cells
How do tumors evade the immune response?
By producing immunosuppressive cytokines
By promoting immune cell proliferation
By increasing MHC I expression
By enhancing T cell activation
What is the role of NK cells in anti-tumor immune response?
