Now, picture metformin as a diligent traffic cop, ensuring the smooth flow of glucose into the city’s power plants… Read More, a medicationMedicine is the field of science and practice that deals with the prevention, diagnosis, treatment, and cure of disease. Think of it like this: • Your body is a complex machine. • Medicine is like a toolbox, and knowledge is… Read More commonly used to treat type 2 diabetesDiabetes is a chronic condition where your body struggles to regulate blood sugar (glucose) levels. Glucose is like fuel for your cells, and it comes from the food you eat. Insulin, a hormone made by your pancreas, acts like a… Read More, is increasingly being investigated for its potential role in cancerImagine your body as a well-organized society, where each cell plays a specific role. Cancer disrupts this harmony, as a group of cells goes rogue, breaking the rules of normal growth and function. These renegade cells multiply uncontrollably, forming tumors… Read More treatment and prevention.

Metformin’s Anti-Cancer Mechanisms
- AMPK Activation: Metformin activates an enzymeEnzymes are special proteins that speed up chemical reactions in your body. They’re like tiny helpers that get important jobs done quickly and efficiently. Examples: • Digestive enzymes: These break down food into smaller parts your body can absorb. (Example: Amylase… Read More called AMP-activated proteinImagine your body as a bustling construction site, where every structure is meticulously built and maintained.

- mTOR Inhibition: Metformin can suppress the mammalian target of rapamycin (mTOR) pathway, a signaling pathway involved in cell growth and survival. Inhibiting mTOR can slow down cancer progression.
- InsulinYour pancreas produces the super hormone insulin, which is essential to your body’s metabolism. Here’s a breakdown to make it clear: Definition: Insulin acts like a master key that unlocks the door for sugar (glucose) to enter your cells. Glucose… Read More Sensitization: By improving insulin sensitivityInsulin sensitivity refers to how effectively your body’s cells respond to the hormone insulin. Imagine insulin as a key that unlocks the door to your cells, allowing sugar (glucose) from your bloodstream to enter and be used for energy. Here’s… Read More, metformin can indirectly reduce cancer risk. High insulin levels can promote cancer cell growth, and metformin helps mitigate this effect.
- Anti-Inflammatory Effects: Metformin has anti-inflammatory properties, which may contribute to its anti-cancer effects. Chronic inflammationChronic inflammation is like a fire smoldering in your body for a long time. It’s different from the acute inflammation you experience with a cut or a bruise, which is a short-term response to heal an injury. Chronic inflammation, however,… Read More can play a role in cancer development.
