If both benign and malignant tumours are formed by abnormal cell division, what makes malignant tumours cancerous and benign tumours non-cancerous?

If both benign and malignant tumours are formed by abnormal cell division, what makes malignant tumours cancerous and benign tumours non-cancerous?

Power to invade: Tumors are in fact caused by the accumulation of a series of genetic mutations. If something is going to be cancer, the mutations destabilize the genome and eventually mutations give the ability of the cells to invade and spread as they do early after conception. The idea that tumors are "cells dividing too rapidly" is fundamentally wrong and confusing -- it's the loss of controls. ...Read more

Can benign thyroid nodule become malignant?

Can benign thyroid nodule become malignant?

Well...: A thyroid nodule is technically not "benign" unless it's surgically removed and the pathologist found no cancer in the specimen. A nodule that is still in your neck could still be cancerous despite a "benign" biopsy because not all of the nodule is cancerous. Sometime it's just a speck that is cancerous and was missed during the biopsy. That's why it's important to continue to follow the nodule. ...Read more

Can a benign tumor metastasize?

Can a benign tumor metastasize?

No.: By definition, a benign tumor does not metastasize (spread to other sites by invading the blood stream or lymphatic system).
