This article covers the following topics :
Why does immunotherapy cause side effects?
Immunotherapy causes side effects because of its mechanism of action, which involves activating the body’s immune system to attack cancer cells. While immunotherapy is a valuable and innovative cancer treatment, it can also affect normal cells and tissues in the body, leading to side effects. The immune system is a complex network of cells, tissues, and organs designed to defend the body against harmful invaders, such as viruses, bacteria, and cancer cells. When it is activated through immunotherapy, it may inadvertently attack healthy cells as well as cancer cells, resulting in side effects.
There are different types of immunotherapy, each with its specific mechanism of action, but the common goal is to enhance the immune response against cancer. Some of the key reasons why immunotherapy causes side effects include:
1-Non-Specific Targeting: Immunotherapy may activate the immune system in a generalized way, leading to the immune response affecting not only cancer cells but also normal healthy cells. This non-specific targeting can cause side effects.
2-Inflammatory Response: Immune cells release various chemicals (cytokines) when activated, leading to inflammation. Excessive inflammation can cause side effects such as flu-like symptoms, skin rashes, and organ-specific toxicities.
3-Overactivation or Misdirected Immune Response: Sometimes, the immune response may become overactive or misdirected, leading to attacks on healthy tissues or organs. This can result in autoimmune-like side effects.
4-Individual Variation: Each patient’s immune system may respond differently to immunotherapy, leading to varying degrees of side effects.
5-Combination Therapies: In some cases, immunotherapy is used in combination with other cancer treatments like chemotherapy or targeted therapies. These combinations can lead to additive or synergistic side effects.
It’s important to note that not all patients will experience side effects from immunotherapy, and the severity and types of side effects can vary widely among individuals. Many side effects are manageable with appropriate medical intervention, and healthcare providers closely monitor patients undergoing immunotherapy to detect and address any side effects promptly.
While immunotherapy can cause side effects, it has also shown remarkable success in treating certain cancers and has led to long-term remission or even cure in some cases. As with any cancer treatment, the benefits and risks of immunotherapy are carefully considered, and the treatment plan is tailored to each patient’s specific needs and medical condition. Patients are encouraged to discuss potential side effects and treatment options with their healthcare providers to make informed decisions about their cancer care.

Do side effects mean that treatment is working?
Experiencing side effects from immunotherapy does not necessarily mean that the treatment is working or not working. Side effects are primarily a result of the body’s immune response to immunotherapy, rather than a direct indicator of treatment effectiveness against cancer.
Immunotherapy works by activating the immune system to recognize and attack cancer cells more effectively. However, this immune activation can also affect normal healthy cells, leading to side effects. The presence or absence of side effects is not directly related to how well the treatment is targeting cancer cells.
Conversely, the lack of side effects does not imply that the treatment is ineffective. Some patients may have a robust response to immunotherapy without experiencing significant side effects, while others may have a strong immune response accompanied by notable side effects. Each individual’s response to immunotherapy is unique, and the occurrence (or absence) of side effects does not determine the treatment’s efficacy.
The effectiveness of immunotherapy is typically assessed through other means, such as imaging studies (e.g., CT scans, MRIs) to monitor tumor size and response, blood tests to measure specific cancer markers, and overall clinical evaluation by the healthcare team. These assessments help determine if the immunotherapy is having the desired effect on the cancer and whether any adjustments to the treatment plan are necessary.
If you have concerns about the effectiveness of your immunotherapy treatment or are experiencing side effects, it’s essential to communicate openly with your healthcare provider. They can provide you with information about your treatment progress, address any concerns, and ensure that you receive the necessary support and care throughout your treatment journey. Remember that the goal of immunotherapy is to improve cancer outcomes, and your healthcare team is there to guide you through the process and monitor your health closely.
