IUDs may protect against cervical cancer

CANCER DIGEST – Nov. 17, 2017 – Use of intrauterine devices or IUDs to prevent pregnancy may also prevent cervical cancer, a new study from the University of Southern California Keck School of Medicine shows.

An analysis of data from 16 observational studies involving more than 12,000 women worldwide showed that women using an IUD, experienced cervical cancer one-third less often compared to those who didn’t use the devices.

Few people recognize alcohol as a cancer risk

CANCER DIGEST – Nov. 10, 2017 – Alcohol use increases the risk of breast, colon, esophageal and oral cancers according to the American Society of Clinical Oncology (ASCO) the largest organization of cancer doctors in the world.

More worrisome to the doctors were results of its National Cancer Opinion Survey they conducted earlier this year that showed 70 percent of Americans do not recognize drinking alcohol as a risk factor for cancer.

Strength exercise lowers cancer death risk

CANCER DIGEST – Nov. 6, 2017 – People who do push-ups and sit-ups, or other weight-based training have a 23 percent overall lower risk of dying prematurely and a 31 percent lower risk of dying from cancer, according to a new Australian study.
In the largest study to compare the mortality outcomes of different types of exercise researchers found the link between strength-based exercise and death due to different causes.

Study shows beta blockers may treat prostate cancer

Sympathetic-nerve fibers (green) are closely intertwined 
with blood vessels (white) release norepinephrine that 
stimulates vessel proliferation that fuels tumor growth.
CANCER DIGEST – Oct. 20, 2017 – Tracking down how certain nerves promote prostate cancer, researchers at the Albert Einstein College of Medicine have revealed a possible new strategy for halting prostate cancer growth.

In a 2013 Science study the researchers led by Paul Frenette, professor of medicine and cell biology at Einstein, showed that nerves of the sympathetic nervous system, the flight or fight response nerves, promote tumor growth by producing norepinephrine, a chemical that gives a sudden boost to skeletal muscle contractions and rate and force of heart muscle contractions. The researchers found that norepinephrine binds to and stimulates receptors on tumor connective-tissue cells, helping the tumor to spread.

CANCER DIGEST – Oct. 14, 2017 – Researchers have found that a recently approved breast cancer drug may block the action of a trio of cancer-causing genes, known as Ras, which are implicated in a number of other cancers, including non-small cell lung cancer.

The drug neratinib was designed to inhibit enzymes produced by two other genes, EGFR and HER2, which make enzymes that regulate cancer cell growth and resistance to chemotherapy.
