In the third part, they were approached from the perspective of specific cancers. In this fourth part,...
As stated in the introduction, this book consists of five parts each covering a different area. In this first part, we will start with some basic information before we will dive into the sexual consequences of various treatments (in Chaps. 8, 9, 10, 11, 12, and 13) and of the various cancers (in Chaps. 14, 15, 16, 17, 18, 19, 20, 21, 22, and 23). C...
Just as in other areas of life, there are many differences between one group and the other. That goes for society, for health problems and for cancer care. Cancers are different, care systems are different, professionals are different, and patients are different. That is both the bother, the challenge and the spice of our work.
Whereas the former part focused on the various treatment strategies, the focus of this part is on specific cancers.
Cancer and its treatment influence sexuality and intimacy and can do that in many different ways.
This chapter will focus on the various biological elements of sexuality and sexual function.
The previous chapters of this module paid attention to various aspects of preventing sexual decline and of sexual rehabilitation after cancer treatment. This chapter will highlight the potential use and some challenges in the introduction of sexual tools and toys in that process.
To be able to deal with the topic of sexuality after cancer, one needs more than knowledge alone. For proper care, one needs also an amount of skills and a proper attitude.
