What is a malignant Tumour?

Malignant tumors have cells that grow uncontrollably and spread locally and/or to distant sites. Malignant tumors are cancerous (ie, they invade other sites). They spread to distant sites via the bloodstream or the lymphatic system. This spread is called metastasis.

Is a malignant tumor always cancer?

A tumor can be cancerous or benign. A cancerous tumor is malignant, meaning it can grow and spread to other parts of the body. A benign tumor means the tumor can grow but will not spread. Some types of cancer do not form a tumor.

Is a malignant tumor bad?

A malignant primary tumor is more dangerous because it can grow quickly. It may grow into or spread to other parts of the brain or to the spinal cord. Malignant tumors are also sometimes called brain cancer.

What is an example of a malignant tumor?

Can malignant tumors be removed?

In most cancer cases, the treatment goal is malignant tumor removal. Often two or more treatment methods are applied and selected from surgery, chemotherapy, and radiation.

Is malignant tumor curable?

However, malignant tumours will often eventually return after treatment. If this happens, or if you have a secondary tumour, a cure isn’t usually possible and treatment can instead be used to improve symptoms and prolong life. Read more about treating malignant brain tumours.

Can you remove a malignant tumor?
