Scientists witness immune cells devouring live cancer in real time

Australian scientists have made a groundbreaking discovery in cancer research by observing the body’s immune response to tumours in real time. Their findings reveal that immune cells can actively attack and consume live cancer cells—a process previously unseen. This development offers fresh hope for melanoma patients, particularly in a country with one of the highest rates of the disease worldwide. The research centred on macrophages, a type of immune cell, which were seen ingesting and destroying live melanoma cells. Scientists had not expected these cells to behave this way, marking a significant shift in understanding how the body fights cancer.

For 60-year-old Anne Gately, a mother of two, the discovery comes as life-changing news. Her melanoma was first removed 16 years ago but returned aggressively in 2018, spreading throughout her body. Doctors gave her just 12 to 24 months to live. However, after starting an experimental immunotherapy treatment, she entered remission within 97 days. Australia has the highest melanoma rate globally, with nearly 20,000 diagnoses and 1,300 deaths each year. Researchers now aim to enhance immunotherapy by strengthening these immune cells, potentially improving survival rates. Gately herself hopes the treatment could one day extend to other forms of cancer.

The findings provide a clearer picture of how the immune system targets tumours naturally. By harnessing this knowledge, scientists may develop more effective treatments for melanoma patients. For those like Anne Gately, the breakthrough represents a tangible step toward longer, healthier lives.
