How to beat cancer naturally?
Chimeric antigen receptor (CAR) T-cell therapy is a way to get immune cells called T cells (a type of white blood cell) to fight cancer by changing them in the lab so they can find and destroy cancer cells. CAR T-cell therapy is also sometimes talked about as a type of cell-based gene therapy , because it involves altering the genes inside T cells to help them attack the cancer.

The most common side effect of CAR T-cell therapy is called cytokine release syndrome, or CRS. It’s also known as a “cytokine storm.” About 70-90% of patients experience it, but it’s very short-term and only lasts about five to seven days. Most patients describe it as having a severe case of the flu, with high fever, fatigue and body aches. It usually starts around the second or third day after the infusion. It happens because the T cells have been multiplying and attacking the cancer, causing an immune response in the body.

This takes two to three weeks. 3 CAR-T cells are put back into your bloodstream, through a drip. This takes a few hours. 4 CAR-T cells attack and kill cancer cells in the body. You will be closely monitored after having CAR-T therapy.
How does car T work?
CAR-T therapy works by taking some T cells (blood cells that help to protect you from infection and disease) out of your blood, genetically modifying them in a lab so they are much better at finding and killing cancer cells, and then putting them back into your blood to fight the cancer. Research has shown that CAR-T cells can remain in ...
