Low-intensity, specific-frequency ultrasound selectively damages cancer cells
(Whitney J. Palmer/ DiagnosticImaging) — A new low-intensity ultrasound approach can destroy cancer cells while leaving healthy cells unharmed. Investigators from the California Institute of Technology and City of Hope Beckman Research Institute have developed a safer, more targeted approach to ultrasound-based cancer therapies. This approach targets a tumor cell’s unique physical and structural properties, […]

Old drug, new tricks: existing medicines show promise in fighting cancer
(Jim Daley/ Scientific American) — Drugs originally developed to treat diseases ranging from diabetes to alcoholism may have applications in cancer treatment, according to a new study. Researchers tested thousands of existing medications, many of which have already been approved by the U.S. Food and Drug Administration for treating diseases other than cancer, against hundreds […]

Many cancer survivors use alcohol to excess, study reports
(Shari Roan/ Everyday Health) — Almost 35 percent of cancer survivors say they exceed the recommendations for moderate drinking levels, and 21 percent say they have engaged in binge drinking. The statistics emerged from a new study published January 8, 2020, in the Journal of the National Comprehensive Cancer Network. The large number of people […]

Targeted ultrasound kills cancer cells while sparing healthy ones
(Chloe Kent/ MedicalDevice-Network) — Ultrasound waves of scaled intensity and frequency have shown promise in breaking apart different types of cancer cells without harming healthy blood cells. The waves are able to exploit the physical and structural properties of tumour cells, and could eventually offer a safer treatment option for cancer patients. The research, which […]

Cancer death rate in U.S. shows large one-year drop
(Thompson Reuters) — Cancer deaths in the United States fell 2.2 percent from 2016 to 2017 — the largest single-year drop ever recorded —fuelled in large part by progress against lung cancer, the leading cause of cancer death, the American Cancer Society (ACS) reported Wednesday. Overall, cancer death rates in the United States fell 29 […]

Largest study yet offers no clear talc link to ovarian cancer
(Thomson Reuters) — U.S. researchers who conducted the largest study yet into whether applying powder to the genitals increases a woman’s risk of ovarian cancer were unable to definitively put to rest the issue that has prompted thousands of lawsuits against Johnson & Johnson and other companies. Overall, the study did not find a significantly […]

Google AI tool can pinpoint breast cancer better than clinicians
(Erin Brodwin/ Scientific American) — Researchers at Google (GOOGL), working alongside experts at Northwestern University and three British medical institutions, have created an AI model that appears capable of more accurately spotting breast cancer in mammograms than human experts, according to a new study. The AI model both detected cases of breast cancer at higher […]

Acupuncture may ease a common side effect of cancer treatment
(Steven Reinberg/ HealthDay News) — Dry mouth can be a troubling side effect of radiation therapy, but acupuncture may ease its symptoms, a new study suggests. Of 339 patients getting radiation for head and neck cancer in the United States and China, those who had acupuncture had fewer symptoms of dry mouth (xerostomia) than those […]

Breast cancer cells use unexpected mechanism to suck up fats
(Genengnews.com) — The link between high-fat diets, obesity, and cancer has grown stronger over the past several years. Yet, the underlying molecular mechanisms have been slow to surface. Now, investigators from Dartmouth College and the Dartmouth-Hitchcock Norris Cotton Cancer Center set out to understand how fat from the diet might influence breast cancer (BC) cells. […]

Getting the recommended amount of physical activity is tied to lower risk of cancer, study says
(CNN) — A new study sheds light on one potential health benefit of exercise: a lower risk of certain cancers. The study, published Thursday in the Journal of Clinical Oncology, analyzed data from more than 750,000 adults in the United States, Europe and Australia, and found that recommended amounts of physical activity correlated with lower […]
