Breast cancer is the most common type of cancer in women and the most common cause of cancer-related death in women between the ages of 45 and 55.

Deciding on the best treatment is a patient’s first and most critical step toward overcoming the cancer. Chemotherapy is a well-known and common type of treatment. However, there are many difficulties with enduring the side effects of chemotherapy, some of which include hair loss, nausea, vomiting, and loss of appetite. In spite of the many side effects, many people choose to undergo chemotherapy treatment because it has proven to be very effective. There is a select group of patients who do not benefit from chemotherapy.

Researchers are currently studying genes of cancer cells to see if pre-treatment tests can help patients determine if chemotherapy would be beneficial before they begin the painful and at times ineffective process.

One of the genetic tests that can patients can use is called Oncotype DX. This test screens the genes of certain types of cancer to see if it will reappear. This test measures the levels of the abnormal cancer cells and calculates a recurrence score. The higher the test score, the higher chance of recurrence. The cost of the testing is so high that they do not want to perform the tests for as long as they need to in order to get the correct results. There is also the specific combination of chemotherapy drug treatment that the studies use to predict whether or not the patient will be...
