78 percent of living right liver donors experienced post-operative complications

More than 78 percent of living right liver donors experienced post-operative complications, according to a new study that uses a replicable complication classification system. Most of the complications were minor, though some were more serious.

MRI detects cancers missed by mammography in breast cancer patients

A unique examination of one treatment center's use of magnetic resonance imaging (MRI) in new breast cancer patients has found MRI to be superior to mammography in finding additional tumors in a breast in which cancer has already been diagnosed, and in detecting new tumors in a patient's supposedly healthy breast.

Percutaneous ethanol injection helps manage bone metastasis in thyroid cancer patients

Percutaneous ethanol injection (PEI), an injection of ethanol (alcohol) through the skin directly into a bone tumor to kill cancer cells, may be a valuable ancillary treatment for thyroid cancer patients whose cancer has spread to the bone.
