<\/span>Introduction<\/strong><\/span><\/h2>\n\n\n\nAfter a cancer diagnosis, hearing that immunotherapy for cancer is an option may leave you wondering how it is different from chemotherapy and what the treatment will involve. Immunotherapy is a cancer treatment that helps the body\u2019s immune system recognise and fight cancer cells 1<\/a><\/sup>.<\/p>\n\n\n\n
Understanding how it works, which cancers it may treat, and the different types of immunotherapies can make the treatment easier to understand. Knowing how immunotherapy is given, along with its benefits, possible side effects, and when to consult a doctor, can also help patients and families make informed decisions about cancer care.<\/p>\n\n\n\n

<\/span>What Is Immunotherapy for Cancer?<\/strong><\/span><\/h2>\n\n\n\nImmunotherapy is a type of cancer treatment that supports the body\u2019s immune system in finding and fighting cancer cells. The immune system normally protects the body from infections and other harmful substances. However, cancer cells can sometimes avoid or weaken the immune response, allowing them to continue growing. Immunotherapy aims to improve the body\u2019s ability to respond to these abnormal cells 1<\/a><\/sup>.<\/p>\n\n\n\n

Did You Know?<\/strong><\/p>\n\n\n\n
\n
Immunotherapy is not a single treatment; it includes several approaches. Examples: Immune checkpoint inhibitors, T-cell therapies, cancer treatment vaccines, and some monoclonal antibodies 1<\/a><\/sup>.<\/li>\n\n\n\n
Immunotherapy is not meant for all types of cancer 2<\/a><\/sup>.<\/li>\n\n\n\n
Depending on the cancer, doctors may combine immunotherapy with treatments such as chemotherapy, radiation therapy or surgery 3<\/a><\/sup>.<\/li>\n<\/ul>\n<\/div><\/div>\n<\/div><\/div>\n\n\n\n
<\/span>How Does Immunotherapy Work?<\/strong><\/span><\/h2>\n\n\n\n
Immunotherapy helps the immune system respond to cancer more effectively. It acts by modifying, enhancing, or redirecting immune responses against cancer.<\/p>\n\n\n\n
The main ways immunotherapy may work include:<\/p>\n\n\n\n
\n
Removing the Immune System\u2019s \u201cBrakes\u201d:<\/strong> Some cancer cells use certain signals to stop immune cells from attacking them. Certain immunotherapies block these signals, allowing immune cells to stay active against cancer.<\/li>\n\n\n\n
Helping the Immune System Recognise Cancer:<\/strong> Some treatments make cancer cells easier for the immune system to identify and target.<\/li>\n\n\n\n
Strengthening Immune Activity:<\/strong> Certain immunotherapies boost the activity of immune cells or provide immune-related substances that help the body fight cancer.<\/li>\n\n\n\n
Bringing Immune Cells Closer to Cancer Cells:<\/strong> Some immunotherapies act as a bridge between immune cells and cancer cells, bringing them together so that the immune cells can attack the cancer more directly.<\/li>\n\n\n\n
Using Modified Viruses to Trigger an Immune Response:<\/strong> Some treatments use specially modified viruses that can infect and destroy certain cancer cells. This can also release signals that help the immune system recognise and attack other cancer cells3<\/a><\/sup>.<\/li>\n<\/ul>\n\n\n\n
<\/span>Which Cancers Can Immunotherapy Treat?<\/strong><\/span><\/h2>\n\n\n\n
Immunotherapy is used for several types of cancer, but its use depends on the specific cancer, its stage and characteristics, and the treatment being considered. It may be used for cancers such as:<\/p>\n\n\n\n
\n
Bladder Cancer:<\/strong> This type is commonly treated with immunotherapy.<\/li>\n\n\n\n
Breast Cancer<\/a>:<\/strong> Used for certain types, such as triple-negative cancer (a type without oestrogen, progesterone, or HER2 receptors).<\/li>\n\n\n\n
Cervical Cancer<\/a>:<\/strong> Used when the cancer is recurrent, persistent or has spread to other body parts or organs (metastatic).<\/li>\n\n\n\n
Colorectal Cancer<\/a>:<\/strong> Used for certain tumours with certain DNA-repair changes.<\/li>\n\n\n\n
Oesophageal Cancer:<\/strong> Used during the advanced stage or before or after surgery.<\/li>\n\n\n\n
Head and Neck Cancers:<\/strong> Used along with surgery\/radiation for certain advanced tumours, and for recurrent or metastatic tumours, specifically those positive for the biomarker PD-L1.<\/li>\n\n\n\n
Kidney Cancer:<\/strong> Given alone or alongside targeted therapy.<\/li>\n\n\n\n
Liver Cancer: <\/strong>Used especially during advanced stages in combination with targeted therapy.<\/li>\n\n\n\n
Lung Cancer:<\/strong> Used for some specific types, including non-small cell lung cancer.<\/li>\n\n\n\n
Blood Cancer<\/a>:<\/strong> Used for certain types such as leukaemia, lymphoma, and multiple myeloma.<\/li>\n\n\n\n
Skin Cancer<\/a>:<\/strong> Used for both pigment-producing (melanoma) and non-pigment-producing (non-melanoma) types 4<\/a><\/sup>.<\/li>\n\n\n\n
Ovarian Cancer<\/a>:<\/strong> May be useful in selected cases, such as recurrent cancer or when the tumour has certain biomarkers, such as MSI-H\/dMMR or TMB-H 4<\/a>,5<\/a><\/sup>.<\/li>\n\n\n\n
Pancreatic Cancer: <\/strong>May be useful for uncommon tumours\/cancers that have DNA-repair biomarkers such as MSI-H, dMMR or TMB-H.<\/li>\n\n\n\n
Prostate Cancer<\/a>:<\/strong> Particularly useful during advanced stages and for cancers with DNA-repair biomarkers or cancer cells that have a large number of DNA changes.<\/li>\n\n\n\n
Stomach<\/a>\/Gastroesophageal Cancer:<\/strong> Useful during advanced stages, especially when tumours have DNA-repair-related biomarkers or PD-L1 proteins on their surface.<\/li>\n\n\n\n
Uterine\/Endometrial Cancer:<\/strong> Used for recurrent cancers or during advanced stages, especially if they have DNA-repair-related markers4<\/a><\/sup>.<\/li>\n<\/ul>
