In cases where cancer is suspected, doctors may take a tissue sample and use immunohistochemistry (IHC) to test for specific antigens using antibodies. IHC not only helps in cancer diagnosis but also helps determine the response to cancer treatment.
If cancer is diagnosed in the first stage, doctors start the treatment. Early-stage breast cancer can often be cured with timely treatment. However, if cancer progresses to the third stage, the situation can become more serious.
