re: Full body cancer scans

Ackually, I thought the OP and the poster above me were the same, so my comment was targeted to the person concerned about bile duct/pancreatic.

The point does remain to the OP: Talk to oncology specialists in the fields where you have family history of cancer. Whole body scans using PET or similar tech are not very sensitive except for subsets of cancers.

Perhaps it makes sense for some folks with certain histories, but not for the general population; therefore, establishing relationships with oncology specialists and discussing your family history along with your current lifestyle and health should be your first step for prevention or early detection.

Hell, for some people surgery to remove organs before cancer develops could be a better choice than whole body scans. For instance and regardless of the presence of cancer on imaging, females with BRCA mutations who no longer want children could have their fallopian tubes removed (not their ovaries) to almost completely eliminate their high chances of developing ovarian cancer.
