Question

what is malignant tumor?​

Answer 1

Answer:

Malignant tumors are cancerous. They develop when cells grow uncontrollably. If the cells continue to grow and spread, the disease can become life threatening. Malignant tumors can grow quickly and spread to other parts of the body in a process called metastasis.

Answer 2

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.
