This is the Cancer Sutra. Made from the partnership of The Bull White House advertising agency and the Stupid Cancer organization, this is the guide to examining your partner during sexy time for cancer.

The reason for the project is explained in its landing page:

"Because fear of cancer can be as bad as cancer itself. 
Because the earlier you detect cancer, the greater the chances 
of treating it successfully. 
Because fear, like cancer, may have the power to spread 
— but they both share one major weakness: Knowledge.

Because of all this, The Cancer Sutra is designed to 
challenge the taboos and conventions about cancer. 
Firstly by talking about how to look for cancer, not just 
find it. Secondly, by bringing the fight against cancer, and 
the prevention of it, out of a place of isolation.

After all, saving lives 
is one thing. Having fun while doing it — well, that’s something 
we can all get behind. (Or in front of, depending.)"
