Norwegian Moon - have a look at this info from Net Doctor, it seems to contradict a lot of what you have just posted:
Circumcision to prevent future disease
Prevention of disease is the second most commonly given reason for circumcision after religious reasons, although the evidence that it has any beneficial effect on future health is very poor. The practice is, more likely, rooted in cultural traditions, although western societies may find this an uncomfortable conclusion.
Penile cancer
Cancer of the penis is an extremely rare disease and, in the early part of the last century, was almost unheard of in circumcised men. However, there is some evidence that circumcision may only offer protection from penile cancer if done in childhood, and adult surgery may not offer any protection.
Poor personal hygiene, smoking and exposure to wart virus (human papilloma virus) increase the risk of developing penile cancer at least as much as being uncircumcised.
Circumcised men are more at risk from penile warts than uncircumcised men, and the risk of developing penile cancer is now almost equal in the two groups. Therefore, routine circumcision cannot be recommended to prevent penile cancer.
Sexually transmitted diseases
Sexually transmitted infections that cause ulcers on the genitals (syphilis, chancroid, herpes simplex) are more common in uncircumcised men. However, urethritis or inflammation of the tube that carries urine through the penis (caused by gonorrhoea and non-gonococcal urethritis) is more common in circumcised men, as are penile warts.
Yeast infection (caused by candida or thrush) is equally common in circumcised and uncircumcised men, although circumcised men are less likely to have symptoms with this infection so they are more likely to unknowingly pass on thrush to their sexual partners.
Far more effective and reliable methods than circumcision exist to reduce the risk of contracting sexually transmitted diseases, such as the use of condoms and adoption of safer sexual practices. Thus circumcision cannot be recommended to prevent these infections.
Human immunodeficiency virus (HIV) infection
Views conflict on whether circumcision can prevent HIV infection. A recent review in the British Journal of Urology concluded that there is no link between having an intact foreskin and HIV infection, whereas another paper in the British Medical Journal takes exactly the opposite view.
Circumcision may be appropriate as a routine preventive measure only in regions that have a high rate of HIV infection, such as sub-Saharan Africa. The existing evidence is inadequate to recommend circumcision as an HIV-preventive measure in the UK.
Cervical cancer
A study in 1947 reported that Jewish women rarely developed cervical cancer and the author attributed this finding to the fact that their sexual partners were circumcised.
Further studies over the past 50 years have had contradictory conclusions, with experts enthusiastically championing the case for and against circumcision. The evidence is inadequate to recommend it as a preventive measure against cervical cancer.
Urinary tract infection (UTI)
Since 1987, several studies have suggested that uncircumcised male infants are up to 10 times more likely to contract a urinary tract infection (UTI). One in 100 uncircumcised infants will develop a UTI, compared with 1 in 1000 circumcised infants.
A UTI is not usually a great risk to health, so it does not seem reasonable to perform a surgical procedure on 100 infants to reduce the risk of one developing UTI.
