Lynch syndrome is an inherited susceptibility to certain types of cancers. It is due to inherited mutations in genes that are important for stopping the replication of cancerous cells.

Colon cancer risk factors include environmental exposure (diet, toxicants, etc.) as well as genetic variants that increase or decrease your susceptibility. Studies show that taking aspirin regularly decreases the risk of colon cancer. Personalization is the key here, though, because that protection from aspirin may only be for people with certain genetic variants.

The World Health Organization listed ‘light at night’ as a possible carcinogen in 2007. Let’s let that sink in for a minute… On the same list of possible carcinogens that includes formaldehyde, aflatoxin, and the HPV virus is something as innocent as artificial light at night.

Have you ever wondered, though, how your cells can survive for a few minutes without oxygen — or how your body manages when oxygen levels are lower than normal? It turns out that we have an innate system that detects when oxygen levels are low and turns on other genes that can help cells survive when precious O₂ is not readily available. This impacts athleticism as well as cancer growth. 

Two good studies on vitamin D levels and SARS-CoV-2 have been published recently in major journals.  Both studies back up all the previous research on vitamin D and immune function.

This isn't really new news...  Having adequate vitamin D levels is vital for good immune function - whether for COVID-19, the flu, other respiratory viruses, Dengue fever, etc. 

A new study puts some statistical evidence to something that we all pretty much know...  a healthy lifestyle is good for longevity. 

The study used data from about a half million people (avg. age 58) and followed them over the course of a decade. The research showed that someone with a healthy or very healthy lifestyle score lived 3.5 to 7.6 years longer. Lifestyle factors included physical activity, diet, smoking, and alcohol consumption.

Importantly, this extension was true both for people with multiple comorbidities (20% of the population group) and for those without. Thus, even if you have something going on - diabetes, high blood pressure, etc - a healthy lifestyle will still reap the rewards.
