The Immune System and Cancer: What is Cancer? Video Series

Summary

Cancer arises when cells grow uncontrollably, often evading detection by the immune system, which normally identifies and attacks abnormal cells. Some cancer cells can block immune responses, making them harder to eliminate. Immunotherapy treatments aim to enhance the ability of immune cells to recognize and destroy cancer cells, offering new hope in the fight against cancer. The National Cancer Institute provides extensive information on cancer and its treatments, highlighting the importance of understanding both cancer biology and innovative therapeutic strategies.

Q & A

What is cancer?

Cancer is a disease characterized by the uncontrolled growth of abnormal cells in the body.

How does the immune system normally respond to cancer cells?

The immune system detects and attacks cancer cells to eliminate them from the body.

Why are some cancer cells able to evade the immune system?

Some cancer cells can develop mechanisms that allow them to avoid detection or block the immune system's attacks.

What are immunotherapies?

Immunotherapies are cancer treatments that help immune cells better detect and kill cancer cells.

How do immunotherapies enhance the immune response against cancer?

They improve the ability of immune cells to recognize and respond to cancer cells, thereby increasing their effectiveness.

What is the role of immune cells in cancer treatment?

Immune cells play a critical role in identifying and destroying cancer cells, which is the basis for immunotherapy approaches.

Can immunotherapy work for all types of cancer?

No, the effectiveness of immunotherapy can vary depending on the type of cancer and the individual patient's condition.

What are the potential benefits of using immunotherapy?

Immunotherapy can lead to prolonged remissions and, in some cases, complete responses in patients with certain cancers.

Are there any risks associated with immunotherapy?

Yes, like all treatments, immunotherapy can have side effects, including immune-related adverse effects, which can affect healthy tissues.

Where can one find more information about cancer and treatments?

The National Cancer Institute is a reliable resource for information on cancer, its biology, and available treatments.
