A study published in June of this year looked for evidence of increased hormone levels in women who take birth control pills. It was motivated by evidence that increased hormone levels are linked with breast cancer. The study examined variation in hormone levels in women taking seven different oral… more
CRISPR is a tool that can be used to edit DNA.  New research shows that the method is also very good at detecting diseases and disease-causing microbes (viruses, and bacteria). CRISPR may also be a potent weapon to detect antibiotic resistance and cancer.  CRISPR is able to detect the cancer-… more
One of the most common drugs used to treat breast cancer is tamoxifen. It works by blocking the activity of estrogen, reducing the growth of cancer cells.  Despite the success of tamoxifen, many cancers eventually become resistant to its effects. The resistance has been shown to be linked to… more
Apart from the possible appearance of genital warts, infection with the Human Papillomavirus (HPV) does not usually cause symptoms and the immune system usually rids the infected person of the virus within two-years. When the infection is not cleared, HPV can cause cervical cancer, oral cancer,… more
Glioblastoma is an aggressive brain cancer, and new treatments are needed. A team of researchers from China Pharmaceutical University has developed a new approach. The researchers loaded immune cells called neutrophils with a chemotherapy drug (paclitaxel), and injected the cells into mice that had… more
Not all cancer cells are equal.  In many cancer types, a small percentage of cancer cells are thought to be the main force behind the growth and spread of tumors. These are called cancer stem cells (CSC).  CSC don't respond well to many treatments, and are likely responsible for many treatment… more
Although all e-cigarettes do not contain nicotine, researchers at the University of Connecticut have found that they may be as dangerous, in some ways,  as unfiltered cigarettes. Through developments in 3D printing, the research team was able to see that e-cigarettes can cause just as much DNA… more
Onions contain quercetin, a type of plant chemical called a flavonoid. Some flavonoids have antiproliferative properties—that is, the ability to block the growth of cells. Recognizing the importance of this kind of molecule, researchers at the University of Guelph conducted a study with five types… more
Cancer cells are broken in many ways. One of those changes controls the way the cancer cells get the energy they need to live and reproduce.  Cancer cells tend to use up sugar much more quickly than healthy cells. Research at the University of Texas has now shown that two different kinds of lung… more
Enriched environments prolonged the lifespan of mice with colon cancer. In a recent study led by Angus-Hill at the University of Utah, male and female mice with tumors in their colons, were exposed to environments that stimulated mental, social and physical activity. Interestingly, the enriched… more
A team of researchers at the Roswell Park Cancer Institute has found that an inactive lifestyle is associated with an increased risk for bladder and kidney cancer. The study was conducted on 1,134 people—of which 208 had bladder cancer, 160 had kidney cancer and 766 did not. By analyzing the… more
Tea, the world's most popular beverage (not counting water), has been shown to cause changes to the genomes of women.  The changes are subtle, slight modifications, called 'epigenetic' changes. Changes were seen in genes known to be involved in controlling the activity of the hormone estrogen.  The… more
For the first time, a cancer drug has been approved based on a genetic defect instead of a specific type of cancer. The drug, pembrolizumab (Keytruda®), works by preventing cancer cells from stopping the immune system. The end result is immune activity against cancer. Up until now cancer drugs were… more
Immunotherapy can lead to long-lasting remission, but most people don’t benefit from this type of therapy and it does not always work. One way this type of therapy works is by stimulating the immune system to create T cells that go into tumors to kill the diseased cells. However, the environment… more
Immunotherapy is a tremendous breakthrough in cancer treatment, but it does not always work.  Researchers at Emory University have developed a test to quickly tell if a specific immunotherapy drug will work for lung cancer patients.  The test will let doctors change treatments if necessary,
  Many people believe that the occurrence of cancer is solely due to things that the patient can control (i.e. diet, exercise, smoking).  However, according to researchers at Johns Hopkins University, cancer frequently occurs due to random errors made by dividing cells. It just happens by chance!… more
Using the best technology is extremely important in cancer.  The introduction of new technologies can provide better diagnosis, treatment and overall results.  That is why the a new PET scanner could be an important innovation.  The new PET scanner can quickly scan the entire body, while using much… more
A 12 year old in Georgia has made discoveries about the cancer-fighting properties of green tea.  For Georgia’s Science and Engineering Fair, Stephen Litt divided 100 worms into 4 groups. From his reading, he thought that a chemical called EGCG, found in green tea, could prevent tumor formation in… more
At the University of Adelaide, researchers have discovered a new pathway that regulates the way prostate cancer spreads around the body.  This is important because, prostate cancer, like many other cancers, is most dangerous when the cancer has spread (metastasized). The research team showed that… more
Everyone gets stressed sometimes. It seems that cancer cells get stressed too. In the case of the cells, the stress is 'real' and is caused the friction or pressure that cells encounter when they move through the body.  Researchers at the University of Rochester want to know how stress affects… more
