The NIH predicts **2 million Americans will be diagnosed with cancer in 2025**, with **breast, lung, prostate, and colorectal cancers making up nearly 50% of new cases**. These same types—along with pancreatic cancer—cause almost **half of all cancer deaths**.

Dr. Paulien Moyaert explains that cancer often kills **not just through tumors**, but through **severe side effects** in the body. In a **viral 3D video**, she shows how **metastatic cancer**, where a single cell spreads and invades organs, can fatally disrupt vital functions.

“If the cancer is in the digestive system, it can block food processing and bowel movements, even causing fatal internal perforation,” she warns. **Pancreatic cancer** is especially deadly, as it can make the **pancreas digest itself**.

In **lung cancer**, patients may die from **asphyxiation** due to oxygen loss. Another major killer is **infection**: “Cancer impairs immunity, and chemotherapy further weakens the bone marrow,” she says. This leads to **anemia**, **immune failure**, and **bleeding problems**.

Around **50% of patients** develop **cachexia**, causing muscle-wasting and weakness. Thankfully, the video stresses that **pain relief is available**: “No one with cancer should die in pain,” Moyaert says.
