Prostate Enlargement

My friend’s father in law suffered from prostate cancer 2 years ago and I understand from him that the cancer cells recently has spread to other parts of his body.

What is the cause of prostate cancer?

The cause of prostate cancer is still unknown and probably like most cancers, the cause of it are from:

Carcinogens, tobacco, age, diet, stress, day to day environment, the immune system and etc.

Initially, I thought that the start of prostate enlargement is eventually leading to prostate cancer but it seems like this is not the case and how will one will know if he has prostate enlargement?  One will start to know if he has started developing prostate enlargement when he frequents the toilet but with little to pee.

Some of the studies has shown that taking saw palmetto regularly aids in the prostate health.  Though I am not too sure if it is true, I still take a product called Perform regularly because it helps in an overall well being of men.
