Colorectal Cancer

In recent years, researchers have considered a potential link between beta-blockers and a decreased risk of cancer. This theory stems from the fact that beta-blockers inhibit the actions of the stress hormone norepinephrine. This, along with studies that found norepinephrine can promote the growth and spread of cancer cells, led researchers to reason that the beta-blockers could have anticancer properties.

However, a recent study published early online in Cancer revealed that the use of beta-blockers showed no reduction of colorectal cancer risk.

For patients with a past history or family history of colorectal cancer, annual fecal immunochemical tests (FITs) detect neoplasias sooner than scheduled 10-year colonoscopies, according to a new study published in the December issue of Gastroenterology. For patients with FIT-positive results, diagnosis was made sooner by 25 months for cancer and by 24 months for advanced adenomas.
