Zinc Oxide can Cause Cancer: Study

image Zinc oxide, chemical present in consumer products may cause cancer, suggests study. According to a study led by a group of researchers from the Nanyang Technological University (NTU), Zinc Oxide is used to absorb harmful ultra violet light, but when it is turned into nano-sized particles, they are able to enter human cells and may damage the user's DNA. This in turn activates a protein called p53, whose duty is to prevent damaged cells from multiplying and becoming ...

Biopsy of Recurrent Breast Cancer Could Modify Treatment

image Breast cancer specialists at Princess Margaret Hospital (PMH) led breast cancer clinical research, which is a second larger study, once again proves comparison of a new biopsy of progressing or recurring cancer with that of the original cancer can order an alteration in treatment. The results are published online today ahead of print in the IJournal of Clinical Oncology/I. Principal investigator Dr. Eitan Amir, medical oncologist in the PMH Cancer Program, University Health Netw...

Study Sheds Light on Risk of Second Cancer in Cancer Survivors

image A study published in ICMAJ/I (ICanadian Medical Association Journal/I) says that cancer survivors have more than double the risk of a second primary cancer of the same type. However the risk of a second primary cancer of another type was only slightly elevated. Danish researchers looked at data for the entire population of Denmark (7 493 705 people) from 1980 to 2007 to determine whether the risk of secondary cancer is linked to the type of cancer found in the first instance...

Researchers Identify New Potential Therapeutic Target for Lymphoma

image A new potential therapeutic target for Diffuse Large B-Cell Lymphoma (DLBCL) has been discovered by researchers from the NYU Cancer Institute, an NCI-designated cancer center at NYU Langone Medical Center. The former is the most aggressive and common type of lymphoma in adults. The new study, published in the November 23 issue of iNature/i, reveals the underlying molecular mechanism contributing to the development of lymphomagenesis. "We have discovered that the prot...

Genetic Predisposition to Bone Cancer

image Genes may increase the risk of developing bone marrow cancer by 30%, according to researchers at UK's Institute of Cancer Research (ICR). Previously it was known that relatives of people with multiple myeloma have a twofold to fourfold increased risk of suffering the disease themselves, but until now, no responsible gene had been identified. Scientists scanned the DNA of 1,675 patients with multiple myeloma and compared them to the genes of around 5,900 healthy people. They found two gene...

Drug Based on Poisonous Flowers Could Halt Breast Cancer Spread

image 'Foxgloves', one of Britain's most popular flowers, could soon be used as treatment to stop spread of breast cancer, suggests a new study. Scientists in the U.S. have revealed that digoxin, a long-established drug based on chemicals found in foxglove, can block the production of a protein called HIF-1, which has been held responsible for the spread of breast cancer. Digoxin has been used for decades to treat conditions like congestive heart failure and irregular heartbeat...

Depression and Anxiety Not Connected to Delayed Resolution of Abnormal Mammograms

image Depression and anxiety may not be connected to delayed resolution of abnormal mammograms./i. Delays in care after abnormal cancer screenings contribute to disparities in cancer out-comes. Women with psychiatric disorders are less likely to receive cancer screening and may also have delays in diagnostic resolution after an abnormal screening test. Vulnerable populations of women, as defined by low income or with racial/ethnic minority status, are less likely to receive standard prev...

Psychiatric Disorders in Women may Not Affect Cancer Diagnosis

image It is believed that Psychiatric disorders could be a hindrance to timely medical care among vulnerable populations. Earlier studies had shown that women victims of psychiatric disorders were less likely to receive cancer screening and may also experience delays in diagnostic resolution following an abnormal mammogram and/or pap test. A new investigation looked into whether pre-existing depression may actually make a difference to the time taken to diagnostically resolve an abnor...

Many People Not Given Cancer Diagnosis Within First Two Visits to Doctor

image Nearly a quarter of people have to wait for at least a month and visit their doctors for four or five times before their cancer is diagnosed, a new study by the Royal College of General Practitioners reveals. According to the study, more than 75 percent of patients who have been diagnosed with cancer were given the diagnosis within the first two visits to the doctors. However a substantial percentage of the patients have to visit at least four or five times before the doctors can correc...

Prevalence of BRAF Mutations in Thyroid Cancers Makes Them a Therapeutic Target

image The most common form of thyroid cancer is known as papillary carcinoma. Research has shown that approximately one quarter of these carcinomas have mutations in the BRAF gene. The prevalence of such mutations is even greater in high-grade carcinomas, particularly those that are refractory to standard treatment, which is radioactive iodine (RAI). A team of researchers led by James Fagin, at Memorial Sloan-Kettering Cancer Center, New York, has now identified a way to potentially exploi...
