Making substances in a lab that are just like immune system components and using them to help restore or improve how your immune system works to find and attack cancer cells. In the last few decades immunotherapy has become an important part of treating some types of cancer.
What happens when the immune system doesn't recognize a new substance?
Any new substance that the immune system doesn’t recognize raises an alarm, causing the immune system to attack it. For example, germs contain substances such as certain proteins that are not normally found in the human body. The immune system sees these as “foreign” and attacks them.
Why does the immune system have a tough time targeting cancer cells?
This is because cancer starts when normal, healthy cells become changed or altered and start to grow out of control. Because cancer cells actually start in normal cells, the immune system doesn’t always recognize them as foreign. Clearly there are limits on ...
What does the immune system do?
Your immune system is a collection of organs, special cells, and substances that help protect you from infections and some other diseases. Immune cells and the substances they make travel through your body to protect it from germs that cause infections. They also help protect you from cancer in some ways.
How does the immune system fight cancer?
Clearly there are limits on the immune system’s ability to fight cancer on its own, because many people with healthy immune systems still develop cancer: 1 Sometimes the immune system doesn’t see the cancer cells as foreign because the cells aren’t different enough from normal cells. 2 Sometimes the immune system recognizes the cancer cells, but the response might not be strong enough to destroy the cancer. 3 Cancer cells themselves can also give off substances that keep the immune system from finding and attacking them.
Does the immune system recognize cancer cells?
Sometimes the immune system recognizes the cancer cells, but the response might not be strong enough to destroy the cancer. Cancer cells themselves can also give off substances that keep the immune system from finding and attacking them.

The immune system normally eliminates damaged or abnormal cells. trick the immune system into helping cancer cells stay alive and grow.
How many types of cancer are there?
There are more than 100 types of cancer. Types of cancer are usually named for the organs or tissues where the cancers form. For example, lung cancer starts in the lung, and brain cancer starts in the brain. Cancers also may be described by the type of cell that formed them, such as an epithelial cell or a squamous cell.
Why do genetics cause cancer?
Genetic changes can also happen because of errors that occur as cells divide. Most often, cancer-causing genetic changes accumulate slowly as a person ages, leading to a higher risk of cancer later in life.
How do cancer cells affect the microenvironment?
Cancer cells can change the microenvironment, which in turn can affect how cancer grows and spreads. Immune system cells can detect and attack cancer cells. But some cancer cells can avoid detection or thwart an attack. Some cancer treatments can help the immune system better detect and kill cancer cells.
What is the term for cancer that occurs when cells divide uncontrollably and spread into surrounding tissues?
This is called metastasis. Cancer is a disease caused when cells divide uncontrollably and spread into surrounding tissues. Cancer is caused by changes to DNA. Most cancer-causing DNA changes occur in sections of DNA called genes.
What is cancer in the body?
The Definition of Cancer. Cancer is a disease in which some of the body’s cells grow uncontrollably and spread to other parts of the body. Cancer can start almost anywhere in the human body, which is made up of trillions of cells. Normally, human cells grow and multiply (through a process called cell division) to form new cells as ...
What are the causes of cancer?
Genetic changes that cause cancer can happen because: 1 of errors that occur as cells divide. 2 of damage to DNA caused by harmful substances in the environment, such as the chemicals in tobacco smoke and ultraviolet rays from the sun. (Our Cancer Causes and Prevention section has more information.) 3 they were inherited from our parents.
What is the difference between a medical oncologist and a surgical oncologist?

The future of cancer treatment lies in providing patients with an even greater level of personalization. Doctors are beginning to offer treatment options based on the genetic changes occurring in a specific tumor.
What is radiation therapy?
Radiation therapy: using X-rays to kill cancer cells. The same cancer type in one individual is very different from that cancer in another individual. Within a single type of cancer, such as breast cancer, researchers are discovering subtypes that each requires a different treatment approach.
What is cancer in the body?
What is cancer? Cancer is the uncontrolled growth of abnormal cells in the body. Cancer develops when the body’s normal control mechanism stops working. Old cells do not die and instead grow out of control, forming new, abnormal cells. These extra cells may form a mass of tissue, called a tumor. Some cancers, such as leukemia, do not form tumors.
Cancer is more than just one disease
There are many types of cancer. Cancer can develop anywhere in the body and is named for the part of the body where it started. For instance, breast cancer that starts in the breast is still called breast cancer even if it spreads (metastasizes) to other parts of the body.
What causes cancer?
Cancer cells develop because of multiple changes in their genes. These changes can have many possible causes. Lifestyle habits, genes you get from your parents, and being exposed to cancer-causing agents in the environment can all play a role. Many times, there is no obvious cause.
What is the cancer stage?
When a cancer is found, tests are done to see how big the cancer is and whether it has spread from where it started. This is called the cancer's stage.
How does cancer spread?
Cancer can spread from where it started (the primary site) to other parts of the body.
