There are hundreds of cancer types affecting various parts of the body. Prostate cancer is the most common one, as reported by the National Cancer Institute (NCI). Over 240,000 new prostate cancer occurrence is expected by the NCI to take place in the US in 2012. The least encountered type is pancreatic cancer with 43,920 new incidence expected in 2012. Recently, the Telegraph reports about a type of cancer resulting from metal-on-metal hip devices .
The NCI listed the most common cancer types that have the greatest frequency in the US. In no particular order, these include:
• Bladder cancer
• Breast cancer
• Colon and rectal cancer
• Endometrial cancer
• Kidney or renal cancer
• Lung cancer
• Non-Hodgkin Lymphoma
• Pancreatic Cancer
• Prostate Cancer
• Thyroid Cancer
Hip Product May Cause Cancer
Results from a British study of 72 hip patients reveal genetic damage to the bladders in 17 patients, says the Telegraph. Of the 17 patients injured by the metal-on-metal hip replacements, three developed “full-blown cancer.”
Design problems with metal-on-metal hip implants, particularly the DePuy ASR hip devices, may cause the metal components to rub against each other and shed microscopic metal particles into the body. The metal particles shed from metal-on-metal hip replacement implants may increase the amount of some metals in the blood, such as chromium and cobalt. This may cause metallosis (blood poisoning) and genotoxicity (genetic damage). Furthermore, tumors and cancer may also arise because of cobalt and chromium in the patient's blood.
The Agency for Toxic Substances and Disease Registry says that when cobalt was put directly into the muscle or under the skin, cancer develops. Based on this research, the World Health Organization's (WHO) International Agency for Research on Cancer says cobalt found in hard metals as a potential carcinogen for humans.
Flawed Hip Device Recalled
There are around 93,000 recipients of the ASR XL Acetabular System and the ASR Hip Resurfacing System worldwide. After the release of data presenting defectiveness in one out of eight patients to whom they were implanted, the two devices were pulled back.
“It is a complete untruth that DePuy did not have reason to withdraw the ASR before now; we have been telling them since 2007, but they allowed it to be used on thousands of people,” says Dr. Stephen Graves, the director of the National Joint Replacement Registry in Australia.
The press statement released by a legislative panel in Australia says that “many people could have avoided considerable pain, suffering and diminished quality of life if the company had acted in a responsible manner to known problems with these devices.” Affected patients have been filing a hip replacement lawsuit against Johnson & Johnson.
