Pertuzumab is a targeted therapy medication that is used in the treatment of certain types of cancer, specifically HER2-positive breast cancer. It works by blocking the HER2 protein, which is overexpressed in some cancer cells, from sending signals that promote the growth of cancer cells. By inhibiting this protein, pertuzumab can help slow down or stop the growth of cancer cells, ultimately leading to better outcomes for patients.

This medication is typically used in combination with other cancer treatments, such as chemotherapy and trastuzumab, to provide a comprehensive approach to fighting cancer. Pertuzumab has been shown to be effective in both early-stage and metastatic HER2-positive breast cancer, and has been approved by the FDA for use in these settings.

As with any medication, pertuzumab does come with potential side effects. These can include diarrhea, nausea, fatigue, and a decreased white blood cell count. It is important for patients to discuss these potential side effects with their healthcare provider before starting treatment, and to report any new or worsening symptoms while taking pertuzumab.

Overall, pertuzumab is an important tool in the fight against HER2-positive breast cancer, and has been shown to improve outcomes for many patients. If you have been diagnosed with this type of cancer, talk to your healthcare provider about whether pertuzumab may be a good treatment option for you. They can help you weigh the potential benefits and risks of this medication, and develop a treatment plan that is tailored to your individual needs.
