Tumor-associated antigens can be found in which cells?

Explanation:
Tumor-associated antigens are not strictly cancer-specific; many of them come from normal self-proteins that can be expressed in healthy tissues as well, sometimes at low levels or under certain conditions. In cancer, these antigens can be overexpressed, altered, or presented in a way that makes them more noticeable to the immune system. Because of this overlap, the same antigen can appear on benign cells too as well as on cancer cells. That’s why the best answer is that tumor-associated antigens can be found in both benign and cancer cells.
