Oestrogen, Progesterone and Puberty Blockers
It's very unlikely that you'll be asked to stop taking feminising hormones if you either currently or previously had prostate cancer. Some feminising hormones (such as anti-androgens and testosterone blockers) are actually used to treat prostate cancer. This type of treatment for prostate cancer is called hormone therapy.
If you're starting cancer treatment, your doctor might suggest that you use a different type of oestrogen. You won't have to change your feminising hormones if you don't want to. Your doctor should talk you through the advantages and disadvantages of each treatment, and if they might impact your gender affirming care. If you're concerned, you can book an appointment to speak to one of our doctors.
Testosterone
Individuals with prostate cancer are typically advised against testosterone therapy as part of gender affirming care due to potential risks associated with hormone-sensitive tumours. Testosterone, a primary component of masculinising hormone therapy, can stimulate the growth and proliferation of prostate cancer cells, potentially accelerating tumour growth or increasing the risk of cancer recurrence. Therefore, testosterone therapy is contraindicated in individuals with a history of prostate cancer or those currently undergoing treatment for the disease.
