There is not enough adequate, unambiguous research and studies to show if any level of hormone from beef or dairy affects humans. Such controversy over whether hormones given to beef and dairy cattle affect humans is less scientific and more consequential, theoretical and philosophical. The primary reason that the EU banned use of hormones in livestock was out of concern for the welfare of animals, not the ill-effects on the health of humans.
The American Cancer Society is even unsure about the effects of IGF-1 from milk products has any effect on cancer rates in humans. Many other reputable sources state the same about beef consumption. Studies about beef consumption in humans in relation to semen production in men or rate of puberty in young girls were too ambiguous, as they failed to state where the beef samples originated from: commercial feedlot, or natural grass-finishing operation? Such is what can be easily seen in the Organic Consumers Association report on the claim that growth hormones from beef cattle "damage" human health, if you look for such pertinant and crucial information.

As far as estrogen from beef playing a role in breast and ovarian cancer, a study from Oxford university (link provided below) shows much ambiguousness as mentioned above. The cancer patients where such results were obtained had a remarkably unknown history of diet, body type, age, family history, exposures to certain carcinogens, and many other factors that may influence incidence to ovarian and/or Breast cancer.
Additionally, there are many sources that dictate how high various plant sources are in estrogen concentration, compared with beef. As an example, a 3 oz. steak from a beef steer that has been implanted contains only 1.9 nanograms of estrogen, whereas a 3 oz. serving of soybean oil contains 138,000,000 ng of estrogen.

Hormones are used on cattle to ensure they fatten up, grow quickly, produce higher yields of milk and produce high financial gains. Hormones used to fatten beef cattle and their availability are synthetic and natural hormones that ensure cattle has a high turn over rate, i.e. they are quickly slaughtered and replaced with new fast growing/fattened cattle. Natural hormones include the hormones estradiol benzoate progesterone or testosterone. The availability of such implants can be found at your local farm and ranch store, or can be purchased from your local large animal veterinarian.

Depends on the ranchers themselves and what market they are targeting, and what cattle they're feeding. Cattle fed on a feedlot diet (which comprises of 97% of the finisher/backgrounding herd in the USA) are not fed hormones, but are given growth hormones via implants in the ears. Heifers, on the other hand, are fed hormones to keep them from going into heat all the time. Angus cattle on such a diet are fed primarily corn-grain-silage mixture to fatten them up prior to slaughter.

It is not clear if these hormones are bad for your health.

Buying organic may make people feel better, but there's little proof these products are safer.
