Most Cancer Types Boil Down to Bad Luck

Study: Heredity and lifestyle play a role in only 1 in 3 cancer types

(Newser) - Roughly two-thirds of cancer types researchers recently studied largely appear to be the result of random mutations and not inherited genes or environmental and lifestyle factors. Reporting in the journal Science , researchers at the Johns Hopkins University School of Medicine investigated 31 common cancer types and found that 22 of... More »

Smart Knife Helps Doctors Find Cancer

It can instantly detect whether tissue is healthy or not in surgery

(Newser) - A nifty new knife that can sniff out cancer might soon be in operating rooms, reports Bloomberg . In its first major test, the "intelligent knife," or iKnife, did spectacularly well—as in, 100% accuracy in 91 cases. Here's how it works: When a surgeon cuts into a... More »

Docs Corral Immune System to Battle Cancer

(Newser) - After decades of false starts, doctors are tapping the immune system to help stave off cancer, USA Today reports. Using proteins from patients' tumors, American researchers have created a vaccine that can put off lymphoma relapses by 14 months. In one study, a cocktail of the vaccine and two other... More »

Glowing Cancer Cells Signal Surgical Leap

New technique takes much of the guesswork out of tumor removal

(Newser) - Surgery to remove tumors has always been a delicate undertaking. Surgeons must try to remove all of the cancerous cells while minimizing the loss of surrounding tissue, a task made harder by the fact that it’s difficult to tell the difference just by looking. No longer: Scientists have found... More »

Robot Worms Offer Cancer Hope

Tiny machines could identify, kill tumors early

(Newser) - Little mechanical “worms” offer the latest hope for early detection—and eradication—of cancer. Researchers have created tiny machines that travel through the body, find tumors that are too small to see in normal scans, and then deliver drugs to kill them. The method has worked to spot tumors... More »

New Cancer Scan Promising, But Much Testing Remains

Dramatic decrease in mortality rate is contested by scientists

(Newser) - A study claiming to dramatically reduce the risk of lung-cancer death is the object of intense scientific debate, Philip Boffey writes in the New York Times. Researchers screened asymptomatic smokers with spiral CT scans, which are more sensitive than the traditional chest X-ray. They estimate 92% of those found to... More »

Skin Cancer of Scalp, Neck Deadlier

Tumors' location indicates survival chances

(Newser) - Melanoma is the rarest, deadliest form of skin cancer, but new research shows that a tumor's location is an indicator of survival chances. An analysis of 50,000 cases over a decade shows patients with lesions on the scalp and neck died twice as quickly as patients with lesions elsewhere,... More »

FDA Clears Avastin for Breast Cancer

Ruling rejects own panel's advice; drug now used for lung, colon treatment

(Newser) - The FDA has approved a drug currently prescribed to treat lung and colon cancer for use on breast cancer patients, the AP reports. The decision defies the advice of the FDA's own advisory panel, which recommended that Avastin not be used to treat breast cancer on the grounds that it... More »

Cancer Pioneer Folkman Dead

Revolutionized treatment by cutting off blood supply to tumors

(Newser) - Cancer researcher Judah Folkman, whose insights and tenacity spawned a whole new branch of oncology, died Monday at age 74, the Boston Globe reports. Folkman pioneered the notion that cancer tumors could be halted if their blood supply was cut off; he persevered despite decades of skepticism in the field... More »

Sun Exposure May Reduce Risk of Lung Cancer

Residents of darker locales have higher rates of disease, new research shows

(Newser) - Lack of exposure to sunlight may increase the risk of lung cancer, a study of 111 countries shows. Smoking is the risk factor most closely associated with the disease, accounting for as many as 85% of cases, but limited access to UV rays is second, the Telegraph reports. Vitamin D,... More »

Researchers Find New Breast Cancer Marker

Discovery predicts which early tumors will become cancerous

(Newser) - Tens of thousands of women may avoid unnecessary treatment for breast cancer in the future, thanks to the discovery of a means to predict which precancerous breast tumors will become cancerous, the Chicago Tribune reports. Researchers found molecular markers that can be used to identify—out of 50,000 women... More »

New Key to Breast Cancer Discovered

Understanding BRCA1 mutation may lead to new treatments

(Newser) - Scientists believe they've made a breakthrough discovery in why a certain genetic mutation can cause a particularly deadly form of breast cancer. Mutations in the BRCA1 gene are apparently linked to the loss of an important protein, PTEN, that checks cell growth, according to a new study in the journal... More »

Lab-Created Mice Resist Cancer

Enhanced activity of a certain gene produces selective cancer cell elimination

(Newser) - A mouse seemingly invulnerable to cancerous tumors has been engineered, Science Daily reports. Researchers at the University of Kentucky introduced a more active version of the Par-4 gene—which appears able to differentiate cancer cells from healthy ones, then kills them—into mouse embryos. They found that the enhanced mice... More »

Blood Test Predicts Alzheimer's

Breakthrough diagnosis could aid treatment

(Newser) - A new blood test not only diagnoses Alzheimer's, but it can predict with 91% accuracy who will suffer from the disease in the future, reports the San Jose Mercury News.
