Tumours are groups of abnormal cells that form lumps or growths. Tumours grow and behave differently, depending on whether they are cancerous (malignant), non-cancerous (benign) or precancerous. Cancer is a group of abnormal cells that usually starts as a tumour and spreads to other parts of the body.
Support groups, associations, and foundations provide information and support to those living with cancer or tumours and their families/caregivers.
