FAQs

  • What role genetic alterations play in cancer?
    • Cancer is caused by alterations (mutations) in specific genes that cause the abnormal growth of cells, causing tumors that can expand to other organs of the body. The genetic alterations may be acquired during the life of the person and be caused by damages in the cells as consequence of factors like tabaquism, sun exposure, etc. The identification of these alterations allows to know the biology of the tumor to figure out how to attack it.
  • How can BioSequence help me with the treatment of my disease?
    • Your oncologist has recommended a genomic study of BioSequence to characterize your tumor and therefore be able to choose the best treatment based on your molecular profile. Thanks to the genomic study your oncologist will have all the information to choose not only the best approved treatment but also promising treatments that still are on clinical trials. In addition to expanding treatment options, the genes analyzed are of great diagnostic and prognostic value.
  • What is the probability that BioSequence find a treatable genetic alteration in my tumor?
    • BioSequence always selects along with the oncologist the most useful genomic study for each patient. This approach is allowing to detect results in the 86% of analyzed cases and in the 88% of them clinically actionable alterations are found (informatives at diagnostic, prognostic and therapeutic level). Because of the experience and the follow-up that BioSequence make of their patients, the 67% of them have had new treatment options, which confirms the big utility of the studies.
  • How are BioSequence genetic tests carried out?
    • To carry out any of the genetic tests that BioSequence offers, a small amount of tumor DNA is required. This DNA is obtained from the tumor tissue during a routine biopsy. When the patient’s oncologist requests the test, the hospital sends a small amount of this tumor tissue to the BioSequence laboratories where the analysis is done.
  • Do I need a new biopsy to fulfill a genomic test?
    • To carry out a genomic test, BioSequence needs to analyze the most recent tumor sample that has been extracted from the patient and that the hospital stores routinely. In case you cannot access to a recent sample that reflects the actual status of the tumor, there already exist options that allow to analyze these alterations in a blood sample. BioSequence will inform you in detail if this is your case.
  • In which moment of my disease should I carry out the study?
    • The specialists recommend carry out these studies to deepen in the knowledge of the tumor, when it doesn’t respond to the first treatments. The studies can be carried out in all types of tumor and in any phase of the disease, although it is recommended to perform the tests as soon as possible to personalize the therapeutic options sooner, avoiding unnecessary side effects.
  • In my family there is a history of cancer, how can I know if I’m going to develop it?
    • Biosequence also offers genetic tests that assess the individual possibility of developing hereditary cancer. We study the familiar cancer history and recommend the most appropriate genetic test to measure the degree of susceptibility through a blood sample.
  • How can I apply for BioSequence services?
    • Your oncologist, you or your relatives can get in touch with BioSequence to organize the sample collection and the results delivery. The BioSequence’s team knows what it takes to manage the disease so we simplify the process as much as possible to make it easy for the patient. The results are delivered within 7-15 days, which enables the oncologist to act quickly.
