Herceptin used in the treatment of HER2-positive breast cancer

Herceptin, known generically as trastuzumab, is a medication primarily used in the treatment of HER2-positive breast cancer. Here are its functions and considerations when using it:

Functions:

1. Targeted Therapy: Herceptin is a targeted therapy that works against cancer cells that have an overexpression of the HER2 protein. This protein promotes the growth of cancer cells. Herceptin attaches to these cells, helping to slow down or stop their growth and promoting their destruction by the immune system.
   
   
2. Adjuvant Treatment: It's commonly used in both early and advanced stages of HER2-positive breast cancer. In the early stages, it might be used after surgery to reduce the risk of cancer recurrence. In advanced stages, it's often part of the treatment regimen to control cancer spread.
   

Considerations when using Herceptin:

1. Cardiac Monitoring: Herceptin can affect the heart, leading to potential heart-related side effects. Regular cardiac monitoring is crucial during treatment to detect any cardiac issues early.
   
   
2. Infusion Reactions: Some people might experience infusion reactions, such as fever, chills, or allergic-type reactions during the administration of Herceptin. Healthcare providers often monitor patients closely during infusions to manage these reactions.
   
   
3. Risk of Infection: Herceptin might lower the body's ability to fight infections. Patients on Herceptin need to be cautious about exposure to infections and should promptly report any signs of infection to their healthcare providers.
   
   
4. Pregnancy and Breastfeeding: It's important to discuss pregnancy plans or breastfeeding while undergoing Herceptin treatment as it can have implications for both.
   

Always remember, the usage and specific considerations regarding Herceptin should be discussed thoroughly with a healthcare professional. They can provide personalized guidance based on an individual's health condition and medical history.
