A new look at the Prostate Cancer

Prostate, a Greek word meaning “protector” or “guardian” is the gland of male reproductive system in most mammals. The function of the prostate is to secrete a slightly alkaline fluid, milky or white in appearance, that usually constitutes roughly 30% of the volume of the semen along with spermatozoa and seminal vesicle fluid. The prostatic fluid is expelled in the first ejaculate fractions, together with most of the spermatozoa. In comparison with the few spermatozoa expelled together with mainly seminal vesicular fluid, those expelled in prostatic fluid have better motility, longer survival and better protection of the genetic material.

Prostate cancer is the second most frequently diagnosed cancer (at 15% of all male cancers) and the sixth leading cause of cancer death in males worldwide. In 2010 it resulted in 256,000 deaths up from 156,000 deaths in 1990. Rates of prostate cancer is the least common in South and East Asia, and more common in Europe, North America, Australia and New Zealand. Prostate cancer has a higher inheridetary factor than breast, ovarian and endometrial cancers, all of reproductive system and develop in the old age (40% for prostate vs. 5-10% for breast, 5% for ovarian and 2-10% for endometrial or uterine cancer)! As discussed in “Breast cancer: Revisited”, all these reproductive systems cancers surprisingly, no matter in males or females, share the genetic link with abnormalities in BRCA1 & 2 that are “tumor suppressor genes”! Prostate cancer has also more of infection risk factors than his female reproductive organ counterparts, specially through STD (Sexually Transmitted Diseases). This makes sense as discussed in “ A new look at Cancer”, “A new look at Infections” and “Trauma and insults” that a common offending cause of human’s cancers are through microbiological offences! This may explain the higher genetic risk in prostate cancer as microbiological insults will leave their long term impacts on the genetic machinery for generations to come! Interestingly among cancers of male and female reproductive organs, only there is a common link between prostate and uterine cervix in causation by HPV (Human Papiloma Virus) infection.

Other than microorganisms that could be blamed for about 30% genetic risk difference between the prostate cancer and female reproductive system cancers, they all seem to share similar risk factors. As discussed in “Breast cancer: Revisited”, “Ovarian and Endometrial Cancers: Revisited”, the common risk factor is in the use of reproductive system itself! Lack or low use of these reproductive organs, e.g. no breastfeeding leading to breast cancer, no reproduction leading to ovarian and endometrial cancers, low use of prostate, the male reproductive organ by lower ejaculation and reproduction by vasectomy, will lead to prostate cancer. Of course the nature gives sufficient time for the use of these reproductive organs, so that is why all these cancers do not develop in young reproductive age but in old age. But if vasectomy is done early on, the prostate cancer may appear earlier than usual late age of >70!

Therefore as discussed in other related posts here, we need to redirect our medicinal efforts from treatment to prevention and educate the public of the high risk of not using their reproductive systems and infections and traumas in the development of such cancers.

  1. The the next occasion I read a weblog, I genuinely hope so it doesnt disappoint me about brussels. Come on, man, Yes, it was my option to read, but I just thought youd have some thing intriguing to state. All I hear can be a great deal of whining about something which you could fix in case you werent too busy looking for attention.

  2. Greetings from Carolina! I’m bored to death at work so I decided to check out your website on my iphone during lunch break. I enjoy the information you provide here and can’t wait to take a look when I get home. I’m shocked at how quick your blog loaded on my cell phone .. I’m not even using WIFI, just 3G .. Anyhow, awesome blog!
