Can cancer always be diagnosed by FNAC or biopsy?

No. At times cancer can be missed by FNAC or biopsy. This is called “false negative” report. It means that the patient has cancer but the report has failed to pick up the correct diagnosis. It happens when biopsy material is taken from a wrong site and thereby producing incorrect result. This is called “sampling error”. Hence, it is of utmost importance that biopsy be taken from the correct site. In the event of a negative biopsy in a suspected cancer case, a re-biopsy should be done, as a false negative report can harm the patient immensely.

Does cancer spread after operation?

No, it does not, provided it is done following certain oncological principles. A cancer should be removed with some healthy tissue around it. This is called negative surgical margin. This is most important in cancer surgery. It means a surgeon’s knife should never go through the cancer but beyond it through healthy tissue. If knife goes through the cancer then there will be spillage of cancer cells and it will spread. Hence cancer must be removed with some healthy tissue around it.
