Immunotherapy is an anti-cancer therapy that uses the body\u2019s own immune system to fight a life-threatening disease like cancer.<\/p>\n
The immune system can identify cancer cells as abnormal cells and tries to against a tumor. It is a network of cells and organs which is formed to protect the body from infections, harmful chemicals, and abnormal cell development. The immune system or the body\u2019s natural defense system recognizes the foreign substance such as a germ enters the body and attacks it to stop it from causing any harm to the body. White blood cells or lymphocytes are an important part of the immune system, and there are two types namely:<\/p>\n

In some cases, the body\u2019s own defense system is incapable of fighting the abnormal cell growth; it may not be strong enough to prevent the growth of cancer cells.<\/p>\n Working of immunotherapy<\/b><\/strong><\/p>\n There are different types of immunotherapy, and all have a different mode of action. Immunotherapy is considered to boost the immune system to work better against cancer cells or remove the barriers to the immune system that stops it to attack the cancer cells.<\/p>\n Immunotherapy and its type<\/b><\/strong><\/p>\n Checkpoint inhibitors- There are checkpoints or complex signals that stop the immune cells from attacking and destroying normal tissue. Cancer cells utilize these checkpoints to slow down the immune response. The discovery in the field of cancer treatment<\/a> is checkpoint inhibitors that block this ability of abnormal cells to use the checkpoints to escape from the immune system and reactivate T cells, which helps in fighting against these abnormal cells.<\/p>\n Ipilimumab is a checkpoint point inhibitors that have been found beneficial in treating kidney cancer, advanced melanoma. \u00a0Pembrolizumab and Nivolumab are also in the same group; these are approved to treat people with melanoma who failed to respond to other treatments. Furthermore, Nivolumab has been shown to be effective in treating patients with metastatic squamous non-small cell lung cancer who failed to respond to chemotherapy.<\/p>\n Immune stimulants- These helps stimulate the immune system to take a more active role in killing cancer cells.<\/p>\n When to use Immunotherapy?<\/b><\/strong><\/p>\n Chemotherapy, radiotherapy, and surgery are still the primary use therapies for cancer treatment, but checkpoint immunotherapy is likely to benefit people with certain types of cancer:<\/p>\n About Immunotherapy treatment<\/p>\n The length of the treatment depends upon:<\/p>\n Checkpoint inhibitors are given intravenously via injections. \u00a0In some cases, more than one type of immunotherapy drug is recommended for ill cancer cells.<\/p>\n\n
