Development of precancerous colon polyps may be linked to long-term antibiotic use

Women ages 20-59 who used antibiotics for two weeks or longer were more likely to have precancerous colon polyps in their 60s than women who did not use antibiotics for an extended period of time in their younger years, suggests a new study published in the medical journal Gut. The study involved 16,600 women 60 years of age and older who took part in the Nurses Health Study in which they provided a history of antibiotic use between the ages of 20 and 59. They had also had at least one colonoscopy between 2004 and 2010. During that time, nearly ... Read More

Selenium nutritional supplement linked to increased type 2 diabetes risk

Selenium is touted for preventing and fighting colorectal cancer. But a 12-year study conducted by researchers with the University of Arizona (UA) Cancer Center found that the nutritional supplements can significantly increase the risk for type 2 diabetes. Selenium has been a popular dietary supplement for decades. It is thought to have antioxidant properties and to play a role in stopping free radicals from damaging cells and DNA. For this reason, it was thought to offer protection against cancer. But a new study questions whether the risks associated with selenium outweigh the perceived benefits. A randomized clinical trial involving 1,824 ... Read More

Testosterone increases colon cancer incidence in lab rats

The male hormone testosterone may cause cancerous tumor growth in the colon, according to new research. Researchers at the University of Missouri College of Veterinary Medicine observed normal levels of naturally occurring colon cancer in a group of male rats. When the testosterone was removed from those rats, colon cancer rates decreased dramatically. When the testosterone was reintroduced, the colon cancer rates returned to normal. It was previously thought that female hormones may have offered some protection against tumor susceptibility. “However, by showing that removing testosterone from rats leads to a dramatic decrease in colon cancer susceptibility, it appears that ...

Diabetics more likely to develop cancer and die from the disease

People with type 2 diabetes are more likely to develop cancer and to die from it than non-diabetics, a new study suggests. Researchers presented their analysis of 20 scientific studies consisting of nearly 2 million people between 2007 and 2012 at the 2013 European Cancer Congress. They found that diabetics had a 23 percent higher risk of developing breast cancer and a 38 percent greater risk of dying from it. They also found diabetics to have a 26 percent higher risk of colon cancer and a 30 percent greater chance of dying from it compared to non-diabetics. “The evidence is ... Read More

More counterfeit vials of cancer drug Avastin found in US

More counterfeit versions of Roche’s best-selling cancer drug Avastin are being distributed to medical facilities in the United States, the Food and Drug Administration (FDA) warned. This is the third time in a year that federal regulators have discovered counterfeit versions of the widely used drug to treat cancers of the colon, kidneys, lungs and brain. The latest batch of counterfeit Avastin does not contain the active ingredient found in the authentic version. The latest batch of counterfeit Avastin was distributed by Medical Device King and is packaged as Altuzan, the Turkish version of Avastin, which is not approved in the ... Read More

Metformin may increase survival in women with ovarian cancer

The diabetes drug Metformin may help women with ovarian cancer live longer, according to a new study published in the journal Cancer. The study showed that women who had ovarian cancer who took Metformin for diabetes treatment had a 20 percent better survival rate from their cancer than women who did not take Metformin. The study compared the survival of 61 patients with ovarian cancer who were also taking Metformin and 178 ovarian cancer patients who were not taking metformin. Sixty-seven percent of the patients who took Metformin were still surviving after five years compared to 47 percent of those ... Read More

Pfizer to remove breast, colon health claims from Centrum vitamins

Pfizer Inc., has agreed to remove the “breast health” and “colon health” claims from the label of its widely used Centrum multivitamins following allegations of deceptive advertising from a consumer watchdog group. The nonprofit Center for Science in the Public Interest (CSPI) threatened to sue Pfizer if it did not remove deceptive claims on its label, such as the vitamins supporting “energy and immunity,” “heart health,” “eye health,” “breast health,” “bone health,” and “colon health.” “Those claims of breast and colon health implied that the supplements would prevent breast and colon cancer – disease prevention claims that supplement manufacturers can’t ...

Counterfeit cancer drug traced back to distributors in Egypt

Counterfeit vials of the cancer drug Avastin that were found circulating in Europe and the United States earlier this month contain salt, starch and a variety of chemicals, but none of the active ingredient bevacizumab that fights cancer. Avastin is an injectable medicine made by Swiss drug maker Roche. It is administered to patients at clinics, hospitals and doctors’ offices. It is used to treat various forms of cancer including colon, kidney, brain and lung cancers. Avastin made headlines recently when the Food and Drug Administration (FDA) pulled the drug’s breast cancer indication because it was not proven safe or ... Read More

FDA removes breast cancer indication from Avastin

After months of debate, the Food and Drug Administration (FDA) has ordered that the breast cancer indication for the drug Avastin be removed because it is not proven safe and effective to treat the disease. Breast cancer survivors petitioned an FDA advisory panel earlier this year to keep the drug as a breast cancer treatment. “I never thought that in the United States I would have to beg for a drug that is keeping me and many others alive,” a breast cancer survivor told the panel during a hearing last summer. But the pleas of breast cancer victims fell on deaf ... Read More

Breast cancer indication for Avastin still a ‘no’

Breast cancer survivors pleaded to a Food and Drug Administration (FDA) panel of experts earlier this week to keep the breast cancer indication for the drug Avastin (bevacizumab). Avastin is used for the treatment of colon, kidney, brain and lung cancers. Late last year, the FDA voted to remove the breast cancer indication from the drug because it did not prove safe and effective in studies among patients with breast cancer. The FDA’s recommendation is based on the results of four clinical studies of Avastin in women with breast cancer. The FDA found that the data from those studies indicated ... Read More
