Does colon cancer screening contribute to reduced cancer mortality? – Medical News Bulletin

A new study investigated the association between pre-diagnostic colonoscopy and colorectal cancer deaths, to demonstrate the effectiveness of colon cancer screening. The development of colorectal cancer is a process that involves multiple steps that take place over a long period of time. This long development process allows screening and detection of early-stage, pre-cancerous polyps before…

Promising new urine test for cancer developed by engineers – Medical News Bulletin

A recent mouse study demonstrates the potential for a new urine test for cancer developed by Imperial and MIT engineers. Early cancer screening is often recommended in at-risk population groups. Early detection of cancer has been proven to improve patient quality of life and survival. Despite the benefits of cancer screening, it can often be…

Is there an association between antibiotics and colon cancer? – Medical News Bulletin

Researchers examine if there is an association between antibiotics and colon cancer. They looked into specific colon regions. The use of antibiotics continues to rise every year, recently estimated at 70 billion individual antibiotic prescriptions in 2010.  While sometimes necessary in treating bacterial infections, antibiotics have been associated with a negative impact on gut health….

Can an electromagnetic field be used to prevent spread of breast cancer cells? – Medical News Bulletin

A new study from Ohio State University examined whether electromagnetic fields could be used to prevent the spread of breast cancer cells to other parts of the body. Metastasis, or the spread of cancer cells to new areas of the body by way of the lymph system is responsible for almost 90 percent of cancer-related…

Is there a link between women’s sleep apnea and cancer risk? – Medical News Bulletin

Are women with sleep apnea more likely to get cancer? Researchers recently investigated the relationship between sleep apnea and cancer. An estimated 50-70 million US adults suffer from sleep apnea. There are three primary types of sleep apnea: obstructive, central, and complex. Obstructive sleep apnea (OSA) is the most common form. It occurs when a…

Targeting cancer stem cells: New anti-cancer molecules may prevent metastasis and tumour relapse – Medical News Bulletin

Researchers have uncovered a new class of therapeutic molecules that target the cancer stem cells responsible for metastasis and tumour relapse. Not all cancer cells are the same and various types of cancer cells may exist within the same tumour. Research suggests that a subpopulation of cancer cells, known as cancer stem cells, are responsible…

Exercise linked to decreased colon cancer risk – Medical News Bulletin

The Journal of Physiology published research that highlights the link between exercise and decreased tumour growth in colon cancer.   As time passes by, the baby-boomer generation increases in age and consequently, the global population’s median age also increases. With older age, comes a higher risk of chronic diseases. Cancer, specifically colon cancer, is the…

Breakthrough research could yield new treatments for leukemia in children – Medical News Bulletin

Medical scientists in the United States have discovered the key protein responsible for childhood leukemia. They discussed their findings in Genes & Development. Childhood leukemia, the most common cancer of children in Canada, is a cancer of the white blood cells. Leukemia develops when abnormal white blood cells form in the bone marrow. These abnormal…

How does breast cancer therapy lead to mental health side effects?  – Medical News Bulletin

A recent study described a possible molecular mechanism for how a class of drugs leads to mental health side effects in breast cancer patients. Breast cancer is the most common type of cancer that affects Canadian women and is considered to be the second leading cause of cancer-related death in this gender. Estrogen-positive breast cancer…

Can we selectively block cancer cell growth without affecting normal cells? – Medical News Bulletin

A recent study in the journal Nature Letters has reported a set of chemical inhibitors that can block cancer cell growth but leave normal cells unaffected. One of the biggest hallmarks of cancer is abnormalities in the cell cycle – a process which regulates the timing and the frequency of cell division. The cell cycle…
