In simple words, it means doctors take special cells (T-cells) from a patient’s blood, change them in the lab to find and attack cancer cells, and then put them back into the patient’s body. Many patients who had no other treatment options have found hope through CAR-T cell therapy. In some cases, it has helped people go into complete remission, meaning their cancer disappears for a long time or even permanently. This therapy is very effective, especially for those whose cancer has come back after other treatments. However, the success of CAR-T therapy can vary. Some patients respond very well, while others may not have the same results. The chances of success depend on factors like the type of cancer, the stage of the disease, and the patient’s overall health. That's why it is ve...

Red blood cells (RBCs) play a very important role in keeping us alive and healthy. They are the most common type of blood cells and are responsible for carrying oxygen from the lungs to every part of the body. Without enough red blood cells, our body wouldn’t get the oxygen it needs to function properly. What Do Red Blood Cells Do? Red blood cells contain a special protein called hemoglobin. Hemoglobin picks up oxygen from the lungs and transports it through the bloodstream to tissues and organs. Once the oxygen is delivered, hemoglobin carries carbon dioxide (a waste product) back to the lungs, where it is breathed out. This process happens continuously and keeps our body working smoothly. The Shape and Structure Healthy red blood cells are round, flat, and slightly indented in the middle—like a doughnut without a hole. This shape helps them move easily through blood vessels, even the tiniest ones, so they can deliver oxygen efficiently. These cells are flexible and live for abo...
