The difference between a malignant and benign tumor is that malignant tumors (cancer) can invade adjacent tissues and your cells can disseminate through the body, through the blood or lymphatic circulation, and grow in places far from its origin, giving rise to another malignant tumor. This process is called metastasis.
The benign tumors, although they may be quite large, present no risk of metastasis and do not invade nearby tissues.
In general, your cells grow slowly, similar to what occurs in normal tissue. When removed, usually do not grow back and the patient is cured, while the malignant sometimes reappear.
Benign tumors are usually restricted to a single tumor mass, circumscribed by capsule or adjacent compressed tissues. They manifest themselves through space occupancy and compression.
O malignant tumor characterizes cancer properly speaking, which means "crab" in Latin, perhaps because of the stubborn way the crab attaches itself to the host or because of the visual similarity of the tumor to the animal.
THE cure of a malignant tumor mainly depends on an early diagnosis and treatment adopted by the oncologist.
