In 1989, the acclaimed Hong Kong writer Xi Xi was diagnosed with breast cancer. Her semi-autobiographical novel Mourning a Breast is a disarmingly honest and inventive account of the author's experience of a mastectomy and of her subsequent recovery. The book opens with her putting away a bathing suit. As the routine pleasure of swimming is revoked, the small loss stands in for the greater one. But Xi Xi's mourning begins to take shape as a form of activism. Addressing her reader as frankly and unashamedly as an old friend, she describes what she is going through; finds consolation in art, literature, and cinema; and advocates for a universal literacy of the body. Mourning a Breast was heralded as one of the first Chinese-language books to cast off the stigma of writing about illness and to expose the myths associated with breast cancer. It is a radical novel about creating in the midst of mourning.
