Question

Distinguish between Benign tumor and malignant tumor.

Answer 1

Hint: Tumor is the abnormal growth of cells in the particular area that may be normal cells or the cancerous cells.
These tumors are classified into two types as benign tumor and the malignant tumor. Benign tumors are normal and malignant tumors are cancerous in nature.

Complete Answer:

Nature	Benign tumor	Malignant tumor
Meaning	The benign tumor is a non cancerous tumor and is normal.	Malignant tumor is a cancerous tumor.
Spreading	These cells don’t spread to other tissues or organs and don't invade other areas of the body.	Malignant cells are dangerous and can spread to other organs and tissues.
Dangerousness	It should be cared only at the time when it damages other cells, unless it doesn’t cause any harm to the body.	These are dangerous and the tumors move to the bloodstream and invade other tissues. This process is called metastasis.
Growth	They grow slowly when compared to the malignant.	They grow uncontrollably and fast to other tissues.
Characteristics of cell	They appear as normal cells and these tissues have the definite and clear boundaries.	They are toxic cells and have no such boundaries.
Treatment	They can be removed by the treatment of radiation and chemotherapy.	It may require surgery, radiation, immunotherapy, etc. for its medication.
Re occurrence	They do not occur after they are removed from the particular area.	May occur in the areas even after the removal of the tumor cells.
Symptoms	These cells do not secrete hormones or other substance that induce changes in the body	After the growth, body shows fatigue and weight loss as the symptoms
Example:	Lipoma, fibroids of the uterus etc.	They occur in blood, skin, lungs, intestine, breast and reproductive organs.

Note: The cells can be found as the benign or malignant by the testing of its biopsy by the doctors. Some of the benign tumors are pre-cancerous and convert into the malignant tumors in the future. They must be removed before they convert into cancerous tissues. Examples for this tissue are found in the intestine.
