Question

Cancerous tumors are harmful because they __________. Would it be A or B? A) invade and destroy the surrounding healthy tissues. B) Turn existing healthy tissue into cancerous cells

Answer 1

" A cancerous tumor is a tumor which is considered malignant, meaning that it has the potential to spread to neighboring organs"




"Tumors are masses caused by uncontrolled cell growth. They are also called neoplasms. Tumors occur when cells start to duplicate with no checks in place, causing a proliferation of cells. Normally, the body carefully regulates cell production, ensuring that cells are duplicated as needed, but not allowed to grow uncontrollably. When a cell mutates, however, it duplicates itself rapidly, cloning copies of the damaged cell and creating a neoplasm."
