The additive effects of smoking, diabetes, and poor diet are the biggest risk factors for developing pancreatic cancer.

Diabetes has downstream effects on the heart, eyes, kidneys, and more

High blood sugar levels in untreated diabetes roughen artery walls, increasing plaque buildup, heart disease, and high blood pressure risk. High levels also cause acid to build up in the bloodstream, potentially making the brain swell, the lungs fill with fluid, and the heart to beat arrhythmically—all fatal complications.

People with schizophrenia have triple the risk of developing diabetes

It remains contentious if something inherent about the disease or antipsychotics' side effects (weight gain) are mostly to blame. Some newly diagnosed schizophrenia patients already have insulin resistance, raising questions about if patients' brains are getting enough energy from glucose, and if dietary changes—like a high-fat, low-carbohydrate, moderate-protein diet—may help alleviate symptoms.

Cigarette smoke exposure boosts MS risk by up to 55%, though smokeless tobacco doesn't

The components of the smoke itself are associated with these significantly increased risks, so it's something beyond nicotine itself that drives that risk. What's more, smoking also increases the risk of developing antibodies to MS-treating drugs.

About 40% of cancer cases are linked to preventable risk factors

Maintaining a healthy weight, engaging in regular physical activity, and consuming a balanced diet can lower cancer risk. Research indicates that about 40% of US cancer cases are linked to preventable factors, including poor diet and inactivity. Understanding these mechanisms empowers individuals to adopt healthier lifestyles for cancer prevention.

Explore global maps of cancer prevalence, with incidences that reflect various risk factors, including smoking rates, HPV infections, sunscreen use, and alcohol consumption.

Type 2 diabetes is a chronic disease that develops over time

Almost 90 to 95% of people with diabetes have Type 2 diabetes, occuring when the pancreas doesn't make enough insulin or the insulin fails to work correctly. Insulin malfunction causes the pancreas to crank out increasingly high amounts of the blood sugar-regulating hormone, leading to overwork and reductions in production.

The pancreas releases digestive enzymes and regulates blood sugar

The pancreas weighs about the same as a deck of cards and is smaller than the average adult human hand. This lopsided glandular organ controls blood sugar levels through insulin production and helps the body digest food by creating a neutralizing tonic filled with digestive enzymes.

Diabetes is a chronic disease linked to insulin production and high blood sugar

Diabetes is a chronic, progressive disease caused by a lack of, or problems processing, the hormone insulin, leading to persistently high blood sugar. Around 90 to 95% of cases are Type 2 (chronic and caused by factors like diet and environment). The remainder are Type 1 diabetes (an autoimmune disorder).

Type 1 diabetes, affecting about 5%-10% of people with diabetes, is an autoimmune disorder inhibiting insulin production.

Gestational diabetes occurs when the body can't produce insulin during pregnancy

Globally, pregnant people are increasingly at risk to develop gestational diabetes due to rising maternal ages and obesity rates. The condition is associated with heavier fetal weight, congenital abnormalities, and perinatal mortality, which includes stillbirths and deaths of babies younger than 7 days old.

Many cancers arise from genetic mutations inherited from your parents

These mutations may happen in response to environmental or lifestyle factors, or may be passed down through family members. Genetic testing can be important in catching certain family cancers early and ensuring patients receive the right treatment for their disease.

Diabetes is a hormonal disorder that occurs when the pancreas does not produce enough of a hormone that regulates blood glucose, called insulin, or when the body cannot effectively use the insulin it produces.

At a 2026 cancer conference, news that a novel pancreatic cancer drug doubled survival times in clinical trials led to a standing ovation.

How meal timing factors into health outcomes

The world is trending toward weight gain, a development that comes with a corresponding rise in risk for health conditions, including diabetes and heart disease. This article explores how meal timing has become a factor in nutrition and weight maintenance.

Blood Pressure and Diabetes

New meta-analysis shows blood pressure reductions with ACE inhibitors and ARBs are associated with a lower diabetes risk, but other types of antihypertensive agents have the opposite effect.

Alcohol may be responsible for about 5% of cancer cases and 4% of cancer deaths in the US.

Continual sitting harms your health in a variety of ways

Prolonged inactivity, like sitting for long periods, slows metabolism, weakens muscles and bones, and impairs insulin function. When these negative changes persist over time, the cumulative result is an increased risk of cardiovascular disease, diabetes, and many cancers.

Learn how colorectal cancer is linked to the American diet and chronic inflammation

A University of South Carolina colon cancer researcher offers insights from his own research and notes that more exercise, social support, and eating fruits, vegetables, legumes, and foods like fish and olive oil—often called the Mediterranean diet—are associated with better health—and could improve our colons.

Diabetes 101: Insulin deficiency leads to high glucose levels in the blood

Glucose, the brain's preferred energy source, enters the bloodstream when the body breaks down consumed carbohydrates. To manage this increase in readily available energy, the body releases the hormone insulin, which allows glucose to enter and fuel our cells. Without insulin, glucose remains in the blood, causing health issues.

Stroke risk doubles each decade after age 55

While age is the greatest risk factor, genetics, diet, and overall health play a prominent role in determining individual stroke risk. Prevention focuses heavily on modifiable risk factors. High blood pressure is the single most important controllable risk factor, contributing to both types of stroke.

Ultraprocessed foods are linked with a 58% elevated risk of developing dementia. (Paywall may apply.)

Cancer rates are on the rise among GenXers and Millennials

Cancer rates are rising among Gen X and Millennials, with more cancer diagnoses being made in their 30s and 40s than previous generations. Factors such as prenatal exposures, environmental toxins, and lifestyle choices may contribute to this trend. Memorial Sloan Kettering Cancer Center's experts discuss these issues, exploring how these insights could reshape cancer risk understanding.

People with blue eyes appear to be at elevated risk of developing macular degeneration, perhaps because more light can penetrate their eyes.

One in 10 adults worldwide has diabetes.

Diabetes drug GLP-1 is a peptide (that's what the 'P' is for).

Explore this interactive tool from the National Cancer Institute to calculate your risk of dying from various causes, including cancer.

Lack of Vitamin D seems to be one major factor fueling MS risk

Researchers believe that a combination of factors can elevate MS risk, including a lack of vitamin D exposure in different locales, genetic history, cigarette smoke exposure, and Epstein-Barr virus infection.

This 2022 study is one of the findings that prompted WHO to label aspartame as 'possibly carcinogenic'

This French study analyzed online periodic self-reported food journals from more than 100,000 people for a median of almost eight years and linked aspartame consumption to a roughly 15% increased cancer risk. It found that the people who consumed higher levels of aspartame had elevated cancer numbers—particularly breast and obesity-related cancers.

Overmedication has put type 2 diabetics at risk of low blood sugar

Type 2 diabetics in the US risk dying from low blood sugar, an epidemic traced to a decades-old, multi-million-dollar drug industry campaign encouraging an average blood sugar level below 7%. Contemporary research correlated such levels with reduced risk of eye, nerve, and kidney damage and increased hypoglycemia risk.

An overview of 200 years of diabetes treatment

Diabetes treatment became truly effective after the advent of insulin injections in the early 1900s. Diabetes is becoming increasingly common. Current trends estimate one in three Americans will have diabetes by 2050. This overview explores two centuries of diabetes treatment—starting in 1812—and outline potential challenges to treatment and prevention.

Specific gut microbiome 'fingerprints' are associated with cancer recurrence, with up to 94% accuracy.

Breast, prostate, and lung cancer are the most common forms of cancer.

Black patients are losing their limbs at a rate triple that of other groups due in large part to inequities in diabetes care and management.

Insulin is a hormone that controls blood sugar by helping absorb it into cells

Blood sugar levels increase after a meal when the body starts turning food into usable fuel—sugars, proteins, and more—which are absorbed into the bloodstream through the intestines. Blood sugar levels rise, releasing insulin, and letting sugar in the blood be absorbed into hungry cells, thereby dropping blood sugar levels.

Lung cancer advances are making a big difference

Lung cancer deaths are declining faster than new cases due to advances in treatment. The progress illustrates what is possible, even for a cancer that has long had a poor prognosis.

Addressing lifestyle factors, which influence inflammation, can cure some chronic diseases

In this video, a physician claims that he reversed a patient's Type 2 diabetes in six weeks by addressing inflammation drivers such as diet. More broadly, he argues that society needs to better consider and address numerous disease factors that are modulated by inflammation, such as stress, sleep, diet, and movement.

Every 3.5 minutes in the US, a limb is amputated due to diabetes.
