Plastic surgery facilitates the surgical removal of tumours,
some of which might otherwise be inoperable. The objective of
plastic surgery is to preserve and restore function and appearance
while still allowing adequate treatment of a tumour. Because living
with scarring is a huge social burden, plastic surgeons are
concerned to leave an area looking as normal as possible. Skin
cancers are the most common form of cancer and plastic surgeons are
often involved in cutting these out. The increasing incidence is
primarily due to a combination of over-exposure to the sun and an
ageing population. Head and neck cancers, cancer in the pelvic area
and the removal of large tumours from other parts of the body, may
all involve reconstructive surgery and/or grafts to fill the hole
left by the removal of tumours. When radiotherapy is used in
conjunction with surgery, to kill any remaining rapidly-growing
cancer cells, it may interfere with the blood supply, leaving areas
of necrosis. Radionecrosis can be as big a problem for plastic
surgeons to deal with as the removal of the tumours, requiring
reconstruction and grafting in areas where tissue or bone has
died.
