Scientists Discover Antibody that Kills Prostate Cancer

UnknownUS researchers have found an antibody that hunts down prostate cancer cells in mice and can destroy the killer disease even in an advanced stage, a study showed Monday.
The antibody, called F77, was found to bond more readily with cancerous prostate tissues and cells than with benign tissue and cells, and to promote the death of cancerous tissue, said the study published in the Proceedings of the National Academy of Science (PNAS).
When injected in mice, F77 bonded with tissue where prostate cancer was the primary cancer in almost all cases (97 percent) and in tissue cores where the cancer had metastasized around 85 percent of the time.
It recognized even androgen-independent cancer cells, present when prostate cancer is incurable, the study by researchers at the University of Pennsylvania showed.
F77 "initiated direct cell death of prostate cancer cells... and effectively prevented tumor outgrowth," it said.
But it did not target normal tissue, or tumor tissues in other parts of the body including the colon, kidney, cervix, pancreas, lung, skin or bladder, the study showed.
The antibody "shows promising potential for diagnosis and treatment of prostate cancer, especially for androgen-independent metastatic prostate cancer," which often spreads to the bones and is difficult to treat, the researchers wrote in PNAS.
Currently, the five-year survival rate for metastatic prostate cancer is just 34 percent, according to the study.
Prostate cancer is the second most common cancer among men, claiming half a million lives each year worldwide, according to the World Health Organization.
Study Verifies Mammography Screenings Cause Cancer

A new study presented on December 1 at the annual meeting of the Radiological Society of North America (RSNA) verified that annual mammography screenings may be responsible for causing breast cancer in women who are predisposed to the disease. Epidemiologist Marijke C. Jansen-van der Weide from the University Medical Center Groningen in the Netherlands suggests that doctors should be very cautious when screening younger women, especially those under age 30.
There are many conflicting reports about the benefits of mammography screenings, particularly among younger women below the age of 40. Because there is a high risk among women with genetic or familial predispositions to breast cancer when getting mammograms, Dr. Jansen-van der Weide and her research team are suggesting that these women get an alternative screening. Ultrasounds, MRIs, and heat thermography screenings are some alternatives that do not expose patients to radiation.
The study evaluated women in the high-risk group and determined that low-dose mammography radiation increased these women's risk of developing breast cancer by 150 percent. Women under 20 who have had at least five mammograms are 2.5 times more likely to develop breast cancer than high-risk women who have never undergone low-dose mammography screenings.
Study authors emphasized the fact that doctors should be cautious in administering mammograms to younger women, especially those with a family history of breast cancer. Moderate- to low-risk women were not evaluated in the study. Alternative screening methods were encouraged in order to reduce the risk of women in high-risk groups from being harmed by radioactive exposure.
Comments by Mike Adams
What this study really reveals is that there is no reason for any women to ever receive a mammogram ever again. Ultrasound and thermography should now be the new standard for breast cancer detection screenings, as they do not subject women to excess radiation.
This study also reveals that mammograms are really "repeat business machines" for the cancer industry. When enough women are subjected to mammography, a windfall of future cancer patients is absolutely assured, and this translates into billions of dollars in profits for the businesses invested in cancer: Big Pharma, mammogram machine manufacturers, and so on.
In fact, mammograms represent the slickest marketing gimmick we've ever seen in modern medicine. It's a technology that recruits new patients by actually causing the disease is claims to "detect." No wonder all the cancer industry non-profit groups donate so much money to breast cancer screening -- it's the best way to keep their sponsors in business!
Just take a look at the Susan Komen for the Cure non-profit, and you'll see that a huge percentage of all the money they raise for "finding a cure" is really redirected to funding "free breast cancer screenings" that target poor women. The purpose of this whole scheme is to herd more women into extremely profitable (and extremely dangerous) cancer treatment cancers that generate billions for the cancer industry.
