What is biological treatment for breast cancer and how does it differ from other treatment options?

Breast cancer is one of the most common types of cancer that affects women worldwide. Over the years, various treatment options have been developed to combat this disease. One of the newer and more advanced treatment approaches is biological treatment for breast cancer. In this article, we will explore what biological treatment is and how it differs from other treatment options.

Biological treatment, also known as targeted therapy, is a form of treatment that specifically targets cancer cells and their molecular pathways. It works by interfering with specific molecules involved in the growth and spread of cancer cells. This approach is different from traditional treatment options like chemotherapy and radiation therapy, which target all rapidly dividing cells in the body, including healthy cells.

Unlike chemotherapy, which is a systemic treatment that affects the entire body, biological treatment is more precise and targeted. This means that it can potentially result in fewer side effects for patients.

There are several different types of biological treatments for breast cancer, including monoclonal antibodies and small molecule inhibitors. Monoclonal antibodies are laboratory-made proteins that can recognize and bind to specific target molecules on cancer cells. By binding to these molecules, they can block the signals that promote the growth and survival of cancer cells.

On the other hand, small molecule inhibitors are drugs that can block specific enzymes or proteins involved in the growth and spread of cancer cells. These inhibitors can be taken orally and work by interfering with the signaling pathways that cancer cells use to multiply.

One of the most well-known biological treatments for breast cancer is trastuzumab (Herceptin®). This monoclonal antibody specifically targets and blocks the HER2 protein, which is overexpressed in about 20% of breast cancer cases. By blocking the HER2 protein, trastuzumab can slow down or stop the growth of HER2-positive breast cancer cells.

Other examples of biological treatments for breast cancer include pertuzumab and ado-trastuzumab emtansine (T-DM1). Pertuzumab is another monoclonal antibody that targets the HER2 protein but works in a different way than trastuzumab. T-DM1, on the other hand, is an antibody-drug conjugate that combines the HER2-targeting properties of trastuzumab with the chemotherapy drug DM1.

Overall, biological treatment for breast cancer offers a more personalized and targeted approach to treatment. By specifically targeting the molecular pathways involved in cancer growth and spread, these treatments can be more effective and have fewer side effects than traditional treatment options. However, it is important to note that biological treatments may not be suitable for all breast cancer patients, and the decision to use them should be made in consultation with a healthcare professional.
