Cancer research has changed a lot over the years, moving from general treatments to more targeted ones. In the past, chemotherapy and radiation were the main options, but they affected both healthy and cancerous cells. Now, scientists can study a tumor’s specific genes and create treatments that work better for each person. Immunotherapy, which helps the body’s immune system fight cancer, has also made a big difference, giving hope to people with hard-to-treat cancers.

Better technology has also helped doctors find cancer earlier, which improves survival rates. Artificial intelligence can now look at medical scans and spot cancer sooner. Liquid biopsies, which are simple blood tests, can detect cancer-related DNA without the need for surgery. Researchers are also working on ways to prevent cancer, like vaccines and new medicines. As research continues, cancer treatments are becoming more effective and less harmful, helping people live longer and healthier lives.
