 Imagine, cancer cells navigating through your body, but instead of spreading randomly, they have a favorite destination, your spine. Why this vital structure? A groundbreaking new study has unlocked a surprising answer, and it may change the way we fight cancer. Cancer can spread to any bone, but for several types, the spine takes the brunt of the attack. Breast, lung, and prostate cancers often make this their second home, causing debilitating pain, fractures, and nerve damage. Until recently, the reason for this preference remained a mystery. But then, researchers at Cornell University made a startling discovery, a unique type of stem cell found only in the spine called the vertebral stem cell. These cells, it turns out, produce a special protein called MFGE8. And guess what? This protein acts like a siren song for cancer cells beckoning them towards the spine.
