About 7 months ago my mother in law was diagnosed with a lung tumor. After 2 biopsies, it was determined that they were noncancerous. The doctor she is seeing, after doing a biopsy on her lymph node that was swollen and benign, told her that the belief is that the tumor in her lung is in fact cancer. All the tests have come back negative, but in his words, if it looks like a cat, acts like a cat then it must be a cat. So they are now going to start radiation treatment in a way to shrink the tumor. My question for everyone out there is, how can a tumor test negative but in fact be cancer? Why would we go for the painful biopsy if the test, after being taken 2 times, still can be wrong? Thank you. Jenn SmithView Thread
