The immune system

Questioning Chemotherapy, A Critique of Toxic Drugs in the Treatment of Cancer

Taking Care of Your Immune System
You must do it, like writing this article. There is a bewildering choice of immune enhancing natural supplements available. Liver cancer may not cause any symptoms.

The mechanisms used to evade the adaptive immune system are more complicated. Recognition of this MHC:

Women are more likely to have autoimmune diseases


Some parts of the immune system look for unhealthy cells or something foreign to the body, some send messages to other cells in the body about an attack and others work to attack and destroy micro-organisms that cause infections — like bacteria, viruses, fungi, parasites — or unhealthy cells, like cancer cells. When the immune system is defending the body against infection and disease, it is called the immune response.

The immune system is made up of cells and organs that work together to protect the body and respond to infection and disease. Lymphocytes are white blood cells found in the blood and lymphatic system. They attack viruses, bacteria and other foreign invaders. There are different types of white blood cells but lymphocytes have the most important role in the immune response.

Lymphocytes are also called immune cells. T cells also called T lymphocytes destroy damaged and infected cells in the body and tell B cells to make antibodies. B cells also called B lymphocytes can turn into plasma cells that make antibodies that help fight infection and disease.

B cells can also remember the types of infection and disease the body has fought against in the past. Antibodies also called immunoglobulins are proteins made by B cells that have turned into plasma cells.

Antibodies travel around in the blood. They fight infection and defend the body against harmful foreign substances by recognizing and binding to a substance like a germ that is causing the body to have an immune response.

The foreign substances or germs that antibodies bind to are called antigens. A specific antibody is made by plasma cells to fight a specific antigen. An antibody binds to an antigen like a lock and key. So only an antibody made against a specific antigen can bind to it, much like a key can only open a specific lock. When this happens, white blood cells can find and destroy the substance that is causing an infection or disease.

The bone marrow is the soft, spongy area inside of most bones, where blood cells are made. Many of the blood cells in the bone marrow are not fully developed are immature and are called stem cells. Stem cells change and grow into different types of cells, including blood cells.

Most blood cells grow and mature in the bone marrow. Most blood cells leave the bone marrow and move into the circulating blood and other areas of the body, like the lymph nodes and tonsils, once they are mature. Your immune system has inhibitory pathways for a reason.

These pathways prevent your immune system from indiscriminately attacking healthy cells in the body. When you remove this inhibition they are much more likely to attack the wrong cells and this can cause substantial damage in some patients. There are often gastrointestinal toxicities and use of these drugs significantly increases the incidence of autoimmune diseases 2. Although these drugs show great promise, we are still in the early phases of understanding how to use them more effectively to treat cancer.

More patients need to recognize that there are also natural options that can be used to support your immune system while on conventional cancer therapies. These natural approaches are safe when used properly but you need professional guidance from a licensed Naturopathic Doctor to know what is appropriate for you.

Integrative oncology excels at supporting the immune system during chemotherapy and radiation. These supports should be used during chemotherapy and radiation, not just after the therapy is complete.

There are many effective natural immune supports that are well supported in the scientific literature. One of these supports is a herb known as Astragalus membranaceus. Astragalus is an herb that is commonly given to help fight respiratory infections. It is well established in the scientific literature as an immune-boosting supplement that has applications with cancer 3,4. Oral chemotherapy and chemotherapy by infusion have the same symptoms and side effects.

Along with chemotherapy, patients sometimes receive monoclonal antibodies, a relatively new type of cancer treatment. Made in the laboratory, monoclonal antibodies bind to proteins on the surface of cancer cells called antigens.

Examples of monoclonal antibodies are Herceptin, for treating certain breast cancers, and Rituxan, a therapy for lymphoma. One of the best-known and earliest targeted drugs is Gleevec, which is a major advance in treating chronic myeloid leukemia and GIST — gastrointestinal stromal tumors.

Other targeted therapies are Tarceva and Iressa, both used to treat certain lung cancers. Immunotherapy is one of the hottest and most promising strategies for cancer treatment. These drugs, such as Yervoy ipilimumab and the newly approved Keytruda pembrolizumab have mainly been used to treat melanoma but are being tested against other forms of cancer. Appointments and Second Opinions In a compelling video, Joanna, a Dana-Farber breast cancer patient, describes her initial fears about starting chemotherapy, and talks about what the actual experience was like.

Cancer treatment increasingly takes place at home, as patients receive oral chemotherapy or other types of anti-cancer drugs through pills, tablets, and liquids. Are you taking chemotherapy in pill form?

These printable diaries can help you keep track of your doses and side effects to share with your doctor. You may be taking one or more medications to treat your cancer, blood disorder, or related disease. Learn more about the medications prescribed by your doctor.
