Short answer
Malignant means cancerous. A malignant growth can grow into nearby tissue and may spread to other parts of the body.
What it means
Malignant is the word doctors use for cancer. Malignant cells grow in an uncontrolled way and can invade nearby tissue. Some can spread to other parts of the body.
A pathology report is usually where a malignancy is confirmed, because it is based on looking at cells or tissue under a microscope. Scan reports may say something "looks suspicious for malignancy", which is an opinion that usually needs a biopsy to confirm.
"Malignant" covers many different cancers. The type, grade and stage all affect what it means for each person, and treatment options vary widely.
