Advice columnist and relationship expert Matt Whyman answers:
In facing treatment for cancer, it's only natural to have lots of questions about its impact on your life. Sometimes, these concerns can feel deeply personal. The key is to remind yourself that seeking advice from your medical care team is the surest way to achieve peace of mind.
Can I have oral sex?
As a doctor who specialises in cancer treatment for young people, this is a question that Dr Dan Yeomanson hears often: "There is some concern that chemotherapy drugs can be found in bodily fluids including saliva and semen.
"We recommend using a form of barrier contraception, such as a condom or dam, during oral sex. This minimises the chance of your sexual partner being exposed to chemo."
Speak to your care team
Ultimately, you care team will understand that this is a sensitive issue. They'll seek to put you at your ease with the advice, support and info that you need.
