Final answer:
In most instances, a cancerous area should be excised before embalming to ensure the removal of potentially harmful tissue and to prevent the spread of cancer cells.
Step-by-step explanation:
A cancerous area should be excised in most instances before embalming.
Excision refers to the surgical removal of the cancerous tissue or area. This is typically done prior to the embalming process to ensure the removal of any potentially harmful or diseased tissue.
By removing the cancerous area before embalming, it helps to prevent the potential spread of cancer cells and allows for a safer and more effective embalming process. Furthermore, excising the cancer post-embalming could be more difficult due to the firmer tissue consistency that results from the embalming fluids.
