In summary, lymphocytes were removed from a patient's tumor and injected back into her body after being multiplied. This resulted in the patient being cancer free for two years. According to a Science News article, different T-cells are primed to attack different types of diseases based on their recognition of specific foreign proteins. Immune cells do not normally attack healthy cells, but can recognize mutated cancer proteins as non-self and help fight cancer. These cells are crucial for immunotherapy.

lymphocytes from her tumor were taken out.
Those reacting to her tumor were multiplied an injected back into her.
She has been cancer free for two years.

Interesting. It says they removed T-cells from her body and then used the ones primed to attack the tumor cells. Are different T-cells primed to attack different types of diseases?

Each immune cell recognizes a specific part of a specific foreign protein. So, an immune cell that recognizes a protein from a specific virus is primed to attack that virus (and only that virus). Immune cells normally will not recognize "self" proteins made by the body. This prevents immune cells from attacking healthy cells (though sometimes this goes wrong in autoimmune diseases). Cancer, however, is caused by mutations to various proteins, and sometimes these mutant proteins can be recognized as non-self by immune cells. Immune cells that recognize these mutated cancer genes can help fight cancer and are the ones that are useful for immunotherapy.

1. What is immunotherapy?

Immunotherapy is a type of cancer treatment that uses the body's own immune system to fight cancer cells. It works by boosting the immune system or by teaching the immune system to recognize and attack cancer cells.

2. How does immunotherapy cure breast cancer?

Immunotherapy can cure breast cancer by targeting and killing cancer cells, preventing them from growing and spreading. It also helps the immune system to better recognize and destroy any remaining cancer cells.

3. What are the different types of immunotherapy used for breast cancer?

There are several types of immunotherapy used for breast cancer, including immune checkpoint inhibitors, tumor-infiltrating lymphocytes (TILs), and monoclonal antibodies. These treatments work in different ways to boost the immune system's ability to fight cancer cells.

4. Is immunotherapy a new treatment for breast cancer?

Immunotherapy has been used for several decades to treat different types of cancer, but it has recently gained more attention and success in treating breast cancer. Ongoing research and clinical trials are continuously improving and expanding the use of immunotherapy for breast cancer treatment.

5. What are the potential side effects of immunotherapy for breast cancer?

Like any other cancer treatment, immunotherapy can have side effects. Some common side effects include fatigue, flu-like symptoms, skin reactions, and changes in blood pressure. However, these side effects are usually mild and can be managed with proper medical care.
