Dental X-Rays Linked to Common Brain Tumor

Kevin Anderson - Thursday, April 12, 2012

Researchers, who have published their investigation in the American Cancer Society's journal Cancer, have found a correlation between people who have bitewing exams (an exam that holds a piece of x-ray film held by a tab in between the teeth) on a yearly or more frequent basis are 1.4 to 1.9 times as likely to develop meningioma, the most commonly diagnosed brain tumor in the US. There is also an increased risk with panorex exams (an exam taken outside of the mouth that show all of the teeth on one film). Those who received those exams when they were younger than ten years old had a 4.9 times increased risk of developing cancer, and those who received them on a yearly or more basis had a three times as likely chance of developing meningioma.

Scientists Use Antibody To Shrink Tumors of Different Cancers

Kevin Anderson - Wednesday, March 28, 2012

Researchers at the Stanford University School of Medicine have found that an antibody blocks a protein known as CD 47. This protein sends off signals to the body's immune system telling it to pass it by when the macrophages and other cells that eat invaders come by. CD 47 is found in cancer cells, which is why the body's immune system does not fight cancer cells itself. In mice, this treatment significantly reduced the tumors ability to spread and made the tumors shrink and in some cases disappear within weeks of starting treatment.

Aspirin Reduces Cancer Risk

Kevin Anderson - Thursday, March 22, 2012

In three new studies published in The Lancet, researchers have found that people in their middle age who take low doses of daily aspirin have a reduced risk of dying from cancer. They also found that benefits start to show in two to three years, rather than the ten years than previously thought. Researchers also found that it can treat cancer, showing that it reduces the risk of spreading to other parts of the body by 40% - 50%. However, there are risks associated with taking low doses of aspirin every day. There is an increased chance of internal bleeding, especially in the stomach. Also, if you stop taking daily doses of aspirin you have an increased risk of having a stroke. Researchers recommend consulting with your doctor before starting low doses of aspirin every day.

Colorectal Cancer on the Rise for People Under 50

Kevin Anderson - Tuesday, March 20, 2012

Even though colorectal cancer cases have dropped significantly in the U.S. over the last decade, the cases for people under 50 have gone on the rise. Every year since 1992, the number of people under 50 diagnosed with the disease has increased by 2%, according to the Thomas Jefferson University Hospital. They cite the case of Jessica Nixon, who was diagnosed with rectal cancer at age 25. According to Scott D Goldstein, M.D., of the Thomas Jefferson University Hospital, screening isn't recommended until age 50, so the younger the person, the more likely they are to ignore the symptoms, and so the cases aren't caught early.

Women At Risk For Breast Cancer Could Also Be At Higher Risk for Heart Disease

Kevin Anderson - Thursday, December 22, 2011
Researchers have discovered that women who are at risk for breast cancer could also be at a higher risk for heart disease. Researchers have found that the genes BRCA1 and BRCA2, which mutated forms are found in women with breast and cervical cancer, also regulate heart functions. They discovered in mice that had the mutated gene also were at three to five times the risk of heart failure than in mice that did not have the mutated gene. Researchers believe that the mutated BRCA1 and BRCA2 prevent DNA repair after a heart attack, which is essential to recovery. To view the full article, please click here.

Well-Done Red Meat Can Increase Risk for Prostate Cancer

Kevin Anderson - Thursday, December 15, 2011
In a study led by the University of California, San Francisco, researchers found that men who ate higher amounts of well done red meat had an increased risk for aggressive prostate cancer. The study was conducted between 2001 and 2004, with 470 men with aggressive prostate cancer, and 512 men who were controls that did not have prostate cancer. The men were asked to fill out questionnaires about the amount of meat they had consumed in the past 12 months, as well as the "doneness level". Researchers found that higher consumption of ground beef or processed meats increased the risk for aggressive prostate cancer, as well as that grilled or barbecued meat held an increased risk as well. Researchers also found that men who ate high levels of well done ground beef had twice the risk of developing aggressive prostate cancer as those who ate none.

Gene Discovery Which Prevents Common Form Of Skin Cancer

Kevin Anderson - Thursday, November 17, 2011
Researchers have discovered a gene which prevents a common form of skin cancer known as squamos cell cancer of the skin. They have discovered that when this gene is not present in the cells, it stops the signal telling the cell to stop growing. Without the stop signal, the cells keep growing and eventually forms a cancer. Identifying this gene can lead to therapies which could prevent skin cancer from growing.

Researchers Discover Cancer Feeds on Recycled Cell Waste

Kevin Anderson - Thursday, November 17, 2011
Researchers at the Albert Einstein College of Medicine of Yeshiva University have discovered that cancer cells feed on recycled cell waste. Cancer cells use a process known as "autophagy", which turns spent cell material into reusable energy. Researchers have previously known that cancer cells use large amounts of energy, but what they didn't know was how they acquired it, that is until this discovery. Using this knowledge, treatments can be developed which shrink tumor growth and limit it from spreading to other parts of the body.
