What is the first line of treatment?
First line therapy is the treatment regimen or regimens that are generally accepted by the medical establishment for initial treatment of a given type and stage of cancer. It is also called primary treatment or therapy. The intent of first-line therapy is to cure the cancer if possible. Also called induction therapy, this primary therapy is the first assault of chemotherapy drugs on the malignancy.
What happens if older drugs don't work?
The idea is that if the older drugs and regimens used don’t work, there is less to lose by using the new drug. After years of experience and many patients treated with the new drug, the manufacturer may ask the FDA to expand the labeling to include first-line treatment and/or treatment on other forms of cancer.

What is the first line of treatment for lung cancer?
First-line treatment is usually the standard treatment (the "gold standard") given when someone is diagnosed with a particular disease or condition , such as lung cancer. In other words, it is likely the treatment most oncologists would first choose in treating someone. That said, there are no general "rules" stating which treatment has to absolutely come first, and in addition to that, it's important to work with your oncologist to choose the treatment that is best for you as an individual. Only you can be your own advocate and select the treatments which offer you the best outcome while minimizing the side effects you are willing to tolerate.
What is first line treatment?

In contrast to first-line treatment, second-line treatment is usually a treatment which is chosen after first-line treatment has failed to achieve the goal (either it doesn't work or all, or it works for a period of time and then stops working), or has side effects requiring you to stop using that treatment. Second-line treatments are often inferior to first-line treatments but not always. For example, with metastatic breast cancer, second-line therapy tends not to control the cancer for as long a period of time as first-line therapy.

What are the two types of T cells?
There are two types of T-cells, helper T-cells and cytotoxic T-cells. When either T-cell is a match to the antigen presented by the dendritic cell, it divides rapidly in a process called clonal expansion. Helper T-cells, like the name sounds, go on to help activate the rest of the immune system.
Why do antibodies stick to pathogens?
When the antibodies come in contact with an antigen on a pathogen, they stick to it like glue. The 'glue' slows down the pathogen and allows macrophages to engulf it more easily. Since the outside of the bacteria is covered in antibodies, this process also prevents the pathogen from infecting other cells.
What is the immune system?
Lesson Summary. The immune system is a collection of cells and tissues that protects your body from pathogens. These are three lines of defense, the first being outer barriers like skin, the second being non-specific immune cells like macrophages and dendritic cells, and the third line of defense being the specific immune system made ...
Why do cells activate when the same pathogen is encountered again?
When the same pathogen is encountered again, these cells are immediately activated because they are a match for the antigens. This is what causes immunity. Vaccines actually inject small antigens or inactive pathogens into the body to create this exact response. Lesson Summary.
What is the third line of defense?
If pathogens do get through, your body activates the third line of defense, which is your specific immune system. Your specific immune system is made of white blood cells called lymphocytes: B-cells and T-cells. These cells recognize the pathogen invading specifically, compared to the second line of defense, which is activated by any pathogen.
What are the functions of helper T cells?
Helper T-cells, like the name sounds, go on to help activate the rest of the immune system. The helper T-cell secretes chemical messages called cytokines, which recruit other cells, like macrophages, B-cells, and T-cells to mount an attack. Cytotoxic T-cells, on the other hand, play a more active role in the fight.
Which lymphocytes make antibodies?
B-cells are recruited by helper T-cells and are also activated by dendritic cells. When they are activated, these cells go through clonal expansion and change into plasma cells , which create antibodies.
