Why is the Cancer Spreading?

Androgen, a male hormone, is often called the “fuel” that cancer feeds on in order to grow.1

Your body produces androgens in several places, including:1

why cancer spreading The adrenal glands also produce androgen hormones The prostate cancer cells can also produce testosterone Testosterone, a type of androgen, is mainly produced in the testes

Androgens are very important hormones: they play a big role in the formation of many “male” characterisitics, such as sex drive, male hair growth, muscle tone, and low voice. As well, androgens increase bone formation and red blood cell production.2

There are two types of androgen that play a part in the growth of prostate cancer: testosterone and dihydrotestosterone (DHT). Both have been shown to stimulate cancer growth.2

Knowing that androgens act as fuel for cancer growth, doctors often consider treatments that will stop the production of androgens in a man’s body.2 You can learn more about androgen deprivation therapy (ADT) in the treatment section.
