Sex, age and sun exposure linked to frequency of sunburns

In Danish volunteers, sunburn was typically associated with female sex, younger age, high risk behaviors like sunbathing, and long hours exposed to the sun, according to an article in the April issue of Archives of Dermatology.

Dermatologists use patterns to recognize melanoma

Dermatologists depend on overall pattern recognition and comparison rather than specific analytic criteria to distinguish melanoma lesions (malignant skin cancer) from harmless skin moles, according to an article in the April issue of Archives of Dermatology.

Statins help cut risk for advanced prostate cancer

In a 10-year study of more than 30,000 health professionals, researchers at Johns Hopkins and Harvard found that the longer men take cholesterol-lowering drugs such as statins, the far less likely they are to develop advanced prostate cancer.

Gene expression pattern predicts multiple drug resistance

St. Jude Children's Research Hospital discovery of genetic links to multi-drug resistance gives clinicians new insight into the cause of treatment failure and suggests targets for novel anti-leukemic drugs

Researchers determine structure of binding site of colon-cancer drug Erbitux and its protein target

Researchers at the University of Pennsylvania School of Medicine have determined the precise molecular details of how Erbitux, a recently approved colorectal cancer drug, binds to its target on cancer cells. Knowing this chemical configuration will lead to better drug design for this family of cancer medications.

More pressure to lift 13 year near-ban on silicone-gel breast implants

Hot on the heels of the FDA's rejection of Inamed's attempt to have its Silicone-gel breast implants re-instated, a second manufacturer Mentor has also tried to convince sceptical federal health advisers to the Food and Drug Administration to lift a 13-year near-ban on silicone-gel breast implants.

New approach to fighting cancer, based on nanoscale particles

Researchers at Rice University in Texas have developed a new approach to fighting cancer, based on nanoscale particles that can both detect and destroy cancerous cells. The report appears in the April 13 issue of the American Chemical Society's journal Nano Letters.

Researchers show why mutations in a certain few genes, such as the p53 tumor suppressor gene, are found in different cancers

Scientists have identified some of the first genetic triggers for cancer as mutations in specific oncogenes or tumor suppressor genes. Full-blown tumors and metastatic cancers, however, often exhibit many genetic mutations, sometimes dozens in a given tumor. An important scientific question, and one with significant clinical implications, has been what happens after the initial mutation that leads to dangerous later-stage cancers with multiple damaged genes.

Scientists have discovered the mechanism that enables some CD4 T cells - the main target of HIV - to thwart the virus

The discovery, reported on April 13 in the online version of Nature, could open the door to an entirely new strategy for preventing the spread of HIV infection in the body's cells, according to the senior author of the study, Gladstone Institute of Virology and Immunology Director Warner C. Greene, MD, PhD.

Rates of cervical cancer could jump fourfold to a million a year by 2050

Deaths from cervical cancer could jump fourfold to a million a year by 2050, mainly in developing countries. This could be prevented by soon-to-be-approved vaccines against the virus that causes most cases of cervical cancer- but there are signs that opposition to the vaccines might lead to many preventable deaths. The trouble is that the human papilloma virus (HPV) is sexually transmitted.

Scientists identifiy protein that seems to control the malignant features of brain tumor cells

Scientists from Wake Forest University School of Medicine have identified a protein that seems to control the malignant features of brain tumor cells, suggesting a new treatment target for anti-cancer drugs. The research is reported in the current issue of Molecular Cancer Research.

Black women in the US less likely to access preventative cancer treatments

A report from the University of Pennsylvania School of Medicine in Philadelphia says that black women in the US with a family history of breast or ovarian cancer, are far less likely to seek genetic counselling and possible testing than their white counterparts, and although the reasons for the disparity are not clear, it is suspected that mistrust of both the medical system and advice from primary physicians may be factors.

New invention can easily spot whether cancer has spread

German researchers have come up with a test that measures how stretchy cells are, which could revolutionise the way doctors spot whether cancers have spread, Inventors at the University of Leipzig have produced a laptop-sized gadget which can give a diagnosis using as few as 50 cells and avoids the need to cut out tissue and say it is 1,000 times more accurate than traditional tests.

Technology helps Stanford shed new light on coronary bypass surgery

On March 31, Joel Dyels celebrated his 72nd birthday by having coronary bypass surgery at Stanford Hospital. He also became the third patient at Stanford - and in the United States - to benefit from a new imaging system that lets doctors see the blood pathways they have created while the patient's chest is still open.

Canadian cancer crisis due to aging population

According to a report by the Canadian Cancer Society, Canada's aging baby-boomers and the growing population are creating a cancer crisis, and while survival rates for many major cancers continue to improve, the Society projects that there will be 149,000 new cases of cancer diagnosed this year and 69,500 people will die of the disease, 3,500 more new cases and 1,200 deaths over last year.

Obesity linked to diabetes

A research team headed by Professor Helena Edlund at Umeå University has achieved a breakthrough in our understanding of how obesity causes increased levels of insulin, sugar, and blood fats leading to diseases like type-2 diabetes and liver degeneration. The findings also indicate a direct way to prevent these diseases.
