  schema:description "Some cancer treatments can make it harder or impossible to have children later. Before treatment, your team should discuss this and, if you want, refer you quickly to a fertility specialist. Freezing sperm, eggs, embryos or ovarian tissue are the established options; an injection to rest the ovaries during chemotherapy can be added for some women with breast cancer but does not replace freezing."@en ;
