I must say that I think Mike is truly on to something with his BPH theory.
By the way I am sorry that you are so young and have to deal with all this, but your youth and the fact that you are not ignoring your curcumstance is a pure indicator that you will overcome this.When I was first diagnosed I pondered the question of smoking and a whole host of other popular causes and could really not put my finger on anything that should have led to BC.
Back to BPH: I smoked when I was young just for a few years in my mid-20s and quit took it up again around 30-32 and then quit for good. But, I know I had some BPH problems on and off going as far back as 40 years old, I did not seek treatment until I was in my 50s. I was diagnosed with BC at 58 years old. My diet was always good, lots of veggies, fruit, not too much meat etc. Always an athlete runner, biker, swimmer and sponsored age group triathlete for a number of years in my 30s and 40s.
So, I wonder if there is some group out there that could do a clinical study (it would take years) and see if there is some validity to the BPH theory?
Any way I wish you all the best of luck and my advice is not to dwell on the cause right now and stay on top of those 3 month check-ups and do everything you can to maintain good health. Exercise, eat right, plenty of rest etc. That way you give your body the best chances of successful treatment.
My 2 cents
