But patients shouldn't be deterred from seeking information about improving their sexual health, despite cancer, and they shouldn't have to work up extra courage to get answers. Dr. Nagoski recommends the book "Better Sex Through Mindfulness" by Lori Brotto, who specializes in sexual health interventions for those with cancer and for survivors of sexual trauma.
