New research suggests cancer may do something utterly unexpected: send molecular signals that help the brain defend itself against Alzheimer’s disease. For decades, scientists have noticed a strange pattern. People diagnosed with cancer are statistically less likely to develop Alzheimer’s and people with Alzheimer’s are less likely to get cancer. It looked like a coincidence. Now, a mouse study offers a biological explanation. Researchers implanted human lung, prostate, and colon tumors into mic

Why are brain metastases so critical to detect early? Explore in 3D with VOKA Brain metastases are the most common malignant brain tumors in older adults, often arising when cancer from another part of the body spreads to the brain. They frequently occur in patients with lung, breast, kidney, or colorectal cancer, as well as melanoma. These secondary tumors can lead to a wide range of neurological symptoms — headaches, seizures, cognitive decline, and focal deficits — and in some cases, they may
