Is necrosis fatal?

Necrosis is the death of cells in living tissue caused by external factors such as infection, trauma, or toxins. As opposed to apoptosis, which is naturally occurring and often beneficial planned cell death, necrosis is almost always detrimental to the health of the patient and can be fatal.

Is necrosis curable?

Necrotic tissue is dead or devitalized tissue. This tissue cannot be salvaged and must be removed to allow wound healing to take place.

Is tumor necrosis painful?

Doctors link it with many inflammatory conditions, including forms of arthritis. In a healthy person, tumor necrosis factor (TNF) helps the body to fight off infections.

Cancer can slow down your body’s ability to make red blood cells or interfere with your body’s ability to used stored iron. The cancer you have may make you more prone to becoming anemic.

What happens to dead cancer cells after chemotherapy?

Researchers from Harvard Medical School, Boston, and the Institute for Systems Biology, Seattle, have discovered that the remains of tumor cells killed by chemotherapy or other cancer treatments can actually stimulate tumor growth by inducing an inflammatory reaction.
