syöpärajat

Syöpärajat refers to the concept of cancer margins, particularly in surgical oncology. When a tumor is surgically removed, pathologists examine the excised tissue to determine if any cancerous cells remain at the edges of the removed tissue. These edges are known as the surgical margins.

The presence or absence of cancer cells at the margins is a critical factor in determining the success of the surgery and the likelihood of cancer recurrence. If the margins are "clear" or "negative," it means that no cancer cells were found at the very edge of the tissue removed. This indicates that the entire tumor, as far as could be seen microscopically, was successfully excised.

Conversely, if the margins are "involved" or "positive," it signifies that cancerous cells are present at the surgical edge. This suggests that some tumor cells may have been left behind in the patient's body, increasing the risk of the cancer returning. In such cases, further treatment, such as additional surgery, radiation therapy, or chemotherapy, may be recommended to address the residual cancer. The accurate assessment of syöpärajat is therefore essential for guiding subsequent patient management and improving outcomes.
