 FIGHTING CANCER WITH A 30-MINUTE WORKOUT





Recent research from Edith Cowan University highlights the powerful impact that just one session of vigorous exercise can have on the body’s fight against cancer. According to the findings, a single round of resistance training or high-intensity interval training (HIIT) can prompt your muscles to release myokines—proteins shown to reduce cancer cell growth by as much as 20 to 30 percent.

Francesco Bettariga, the PhD student who led the study, found that both resistance and HIIT workouts boosted myokine levels in breast cancer survivors. This matters because myokines are thought to play a key role in slowing cancer proliferation. The research measured these proteins before, right after, and 30 minutes following a single workout, and the results were precise: exercise triggered a surge in anti-cancer proteins even in those who had undergone cancer treatment.

Exercise isn’t just about fighting cancer in the moment. The study also explored how ongoing physical activity changes body composition—by increasing lean muscle and decreasing fat mass—which in turn helps reduce inflammation. That’s important, since persistent inflammation is known to drive cancer progression and recurrence, and can even weaken the immune system.

Bettariga emphasizes that quick-fix weight loss methods can’t deliver the same benefits. Simply losing weight through dieting may shrink fat, but it doesn’t help you build or maintain muscle—the source of those crucial myokines. “You need exercise to preserve muscle and stimulate these protective chemicals,” he says.

If you’re a cancer survivor or simply looking to lower your risk, incorporating regular, vigorous exercise into your routine could make a real difference. The evidence is mounting: movement is medicine.

DIABETES: CAUSES, SYMPTOMS, MANAGEMENT, AND PREVENTION    Diabetes is a complex, chronic condition that comes in several forms, each with its own causes, risks, and best ways to manage it.  Diabetes alters how your body uses insulin, a substance produced in the pancreas, required by cells to absorb sugar in the form of glycogen. When glycogen is unavailable to your cells, they lack an energy source. The two most common types of diabetes are Type 1 and Type 2 diabetes. Type 1 is primarily an autoimmune issue—your own immune system mistakenly destroys the insulin-producing cells in your pancreas (Nature Reviews Disease Primers) There are rare, less-understood forms as well, often linked to genetics. Type 2 diabetes, which accounts for over 90% of all cases, develops when your body becomes resistant to insulin or doesn’t make enough of it (Nature Reviews Disease Primers; NY.gov). Symptoms can be similar to Type 1, but often develop more gradually and can also include blurred...

Diabetes drugs may reduce the risk of Alzheimer’s.

    Diabetes drugs may reduce the risk of Alzheimer’s. The study finds people taking the drugs have fewer biomarkers, slower cognitive decline. People taking certain drugs to lower blood sugar for type 2 diabetes had less amyloid in the brain, a biomarker of Alzheimer's disease compared to people with type 2 diabetes who are not taking the drugs and those without diabetes. The new study, published in the August 11, 2021, online issue of  Neurology , the medical journal of the American Academy of Neurology, also found people taking these drugs, called dipeptidyl peptidase-4 inhibitors, showed slower cognitive decline than people in the other two groups. In people with type 2 diabetes, the body no longer efficiently uses insulin to control blood sugar. Dipeptidyl peptidase-4 inhibitors, also known as gliptins, can be prescribed when other diabetes drugs do not work. They help control blood sugar when combined with diet and exercise. "People with diabetes have been shown to ...

COLONOSCOPY: WHAT YOU NEED TO KNOW A colonoscopy remains one of the most effective ways to detect and prevent colorectal cancer before it becomes a serious threat. During the procedure, doctors can find and remove precancerous polyps, significantly lowering your chances of developing colorectal cancer later on. Studies consistently show that getting a colonoscopy every 10 years—recommended for most adults at average risk—not only saves lives but also costs less over time compared to other screening methods like yearly fecal occult blood tests (FOBT) (Annals of Internal Medicine). Medical experts generally advise starting regular colonoscopy screenings around age 45 or 50, depending on your health history, and repeating them every decade if no issues are found. This timeline is supported by substantial evidence showing colorectal cancer rates stay very low within ten years of a clean colonoscopy (BMJ). If colorectal cancer or certain polyps run in your family, your doctor might suggest ...
