From what I’ve read on the internet, there are some 10%(I am not sure about this could be up or down, but certainly in the range) of people who never know about such a tumor in their lifetime even though its there.
However, finasteride triggers some sort of hormonal imbalance which probably causes additional cascading effect on other hormones and end up in a hormone imbalanced state. As widely discussed on the site, it also causes receptor issues.
I haven’t researched a lot but based on what i’ve read, this is just one pathway.
Finasteride reduces DHT, DHT differently modulates cortisol(someone has quoted a paper on this site) and i’ve read about a study online(I don’t have a reference to this), excess cortisol blocks conversion of t3 to t4 causing thyroid problems, in additional more stress means more cortisol driving the body in direction of adrenal fatigue… some affected in other ways high prolactin and low fsh and low low LH.In my case its high prolactin and high TSH, but FSH and LH is in normal range. So no one really understands how this drug affects the body. It affects different people in different ways.
It is quite likely that the tumor is caused in some way caused by finasteride.
