Ana es una mujer de 42 años. Recientemente descubrió que tiene cáncer de mama. El doctor le recomienda una mastectomía radical. Al ser una mujer muy atlética, Ana le pregunta al doctor si la mastectomía radical afecta su capacidad de hacer ejercicio.
Will a radical mastectomy affect Ana's ability to exercise?
A radical mastectomy involves the removal of the entire breast tissue, the underlying pectoral muscles (including the major and minor pectoral muscles), and the axillary lymph nodes. In a radical mastectomy, both the major and minor pectoral muscles are removed. This type of mastectomy is also known as Halsted's mastectomy, named after the American surgeon William Stewart Halsted who popularized it. 

In a modified radical mastectomy, the pectoral muscles may be partially or completely conserved. In this case, at least the major pectoral muscle is preserved. This modified approach is becoming more common in the treatment of breast cancer, as it aims to be more conservative. 

Since a radical mastectomy involves the removal of the pectoral muscles, it can affect a person's ability to perform certain exercises that involve these muscles. However, it's not possible to determine the specific impact without a thorough evaluation of Ana's condition and a discussion of her exercise routine with her doctor. 

Therefore, it is not possible to determine with the information given whether a radical mastectomy will affect Ana's ability to exercise.
