How personalized medication is aiding cancer treatment

There is no doubt that personalized medicine is the future. Being able to understand how your body works and reacts to certain drugs allows for a more efficient treatment. However, did you know that certain genetic variations can affect how your body metabolizes certain cancer prevention drugs such as Tamoxifen, too?

Tamoxifen is a drug that is used to treat metastatic breast cancer by stopping the estrogen hormone from reaching a cancerous tumor. In other words, if estrogen is food for the cancer, Tamoxifen cuts off the cancer’s food supply which can stop the tumor from progressing. In cases where breast cancer runs in the family, an individual may take the drug as a precautionary measure, under the guidance of a doctor or specialist.

A report outlining the CYP2D6 genotype and the connection to the drug Tamoxifen has been written to assisting doctors in understanding how to best implement Tamoxifen therapy for breast cancer patients. The focus of the report was to understand the CYP2D6 genotype and how it functions. Depending on the activity level of this genotype, your body may metabolize the drug differently. “In theory, the drug should work like a charm,” said Dr Danny Meyersfeld, CEO of DNAlysis Biotechnology. “However, research shows that if an individual has a low activity level of a gene called CYP2D6, the drug may not work as effectively as it should in the body.”

This information is something that can be found out through DNA testing. “DNA testing does not only help one plan a healthy lifestyle, it helps to understand how to take medication that can help save your life,” Dr Meyersfeld said.

DNA testing can be done through DNAlysis Biotechnology’s Medcheck test under the guidance of Dr. Danny Meyersfeld and his team. The test is noninvasive and can be completed in the comfort of your own home. The test consists of a simple cheek swap, after being purchased through
