Question: Thankyou for answering me before, but i have one more question, is either of the mutations in cancer more deadly then the other? or does it maybe have different questions? thanks

  1. Good question Drew. Different mutations do cause cancers to behave differently. But we are starting to understand this better and use it to our advantage. For example, there is a mutation that drives breast and ovarian cancer (BRCA gene). It turns out that these are very aggressive cancers, because cells with these mutations have no control over how the cell grows, which is quite dangerous. But some people have developed a drug that targets a factor in this pathway, such that the drug actually works BETTER when the BRCA gene is mutated. So if you have this mutation, the bad news is that your cancer may be “worse” but the good news is that the treatment may work better. Make sense?
