It’s been three weeks since she announced in a New York Times op-ed that she underwent the double mastectomy after learning that she carries a gene mutation that puts her at high risk of developing breast and ovarian cancer, which killed her mother. Her revelation galvanized the cancer-survivor community, which called it a major step in destigmatizing the disease and the treatment.

Jolie still has not given an interview about her surgery or health, but she spoke in general about it to reporters on Sunday, saying she felt great and was “very happy to see the discussion of women’s health expanded,” reports the Associated Press.
